1. Fill in the Blanks
a) A place where animals are protected in their natural habitat is called a _________.
b) Species found only in a particular area are known as _______.
c) Migratory birds fly to faraway places because of __________ changes
Explanation:
A place where animals are protected in their natural habitat is called a sanctuary.
Reason - A sanctuary is a secure location. A wildlife sanctuary is a location where untamed creatures can live in safety. A wildlife sanctuary is a piece of territory that has been set aside for the safety of wild creatures living in settings like forests.
Species found only in a particular area are known as endemic.
Reason - The plants and creatures known as endemic species are those that can only be found in a specific geographic location. A tiny island, a mountain range, an estuary, a lake, a nation, or any other specific physical area can contain endemic species.
Migratory birds fly to faraway places because of climatic changes.
Reason - Because of climatic shifts, migratory birds travel to far-off places every year during a specific period. Due to the extremely frigid and hostile weather in their native environment, they must soar to deposit their eggs. The term "migratory birds" refers to animals that travel great lengths to reach another continent.

3. Discuss the effects of deforestation on the following.
a) Wild animals
b) Environment
c) Villages (Rural areas)
d) Cities (Urban areas)
e) Earth
f) The next generation
Explanation:
(A) Deforestation's effects on wild animals
Deforestation is the removal of trees and other plant life from a specific region for the development of industries, farms, or other similar reasons. An ecosystem's plant life is an essential component, and different creatures use it as their native habitat. Endangering plant life will eventually put creatures in a certain ecosystem in danger and may result in their extinction.
(B) Deforestation's effects on environment
The process of photosynthesis in vegetation involves the uptake of CO2 from the environment. If the vegetation in a region is killed, the amount of CO2 in the atmosphere quickly rises. Global warming is a consequence of an increase in CO2 concentrations trapping too much heat energy inside the Earth's atmosphere. As a consequence, the Earth's temperature increases and the natural water flow is disturbed. As a result, shifts in rainfall patterns result in droughts and storms.
(C) Deforestation's effects on villages
The roots of the plants, trees, and other flora firmly anchor the soil granules in their current location. Since there are no plants to keep the soil particles in position in the event of water flow or a strong breeze blowing over the top layer of soil, the soil particles are readily removed. Deforestation operations have recently caused soil runoff to rise. Fertility and nutrients are lost in soil. As a result, territory that was once suitable for cultivation becomes a desert.
(D) Deforestation's effects on cities
Deforestation has raised the danger of natural disasters like floods and drought in metropolitan regions. Because of the elevated CO2 amounts in the atmosphere, it will also result in worldwide warming. Continuous industrial and automotive emissions is what causes global warming. The nearby water flow is also impacted.
(E) Deforestation's effects on Earth
Desertification, droughts, and storms are more likely to occur and are more likely to occur as a result of deforestation. Global warming is brought on by rising atmospheric levels of carbon dioxide. In addition to the disruption of the water cycle, environmental disasters are also more likely.
(F) Deforestation's effects on the next generation
Deforestation actions are steadily altering our ecosystem, both directly and indirectly. Deforestation is the sole source of soil loss, climate change, desertification, drought, the greenhouse effect, floods, and many other issues. In the end, the effects of destruction will be felt by future generations.
4. What will happen if
a) we go on cutting trees
b) the habitat of an animal is disturbed
c) the top layer of soil is exposed
Explanation:
If we go on cutting the trees
The animals will lose their native home if we keep cutting down forests because a crucial component of their ecosystem will be gone. The biodiversity of the impacted regions is decreased as a result. Additionally, the Earth's temperature is rising, which contributes to global warming. The hydrological cycle is then affected by global warming. As a result, shifts in rainfall patterns result in droughts and storms. Soil degradation, global warming, desertification, and greenhouse effect dangers all rise as a consequence.
the habitat of an animal is disturbed
The environment that an animal resides in provides all of its fundamental needs, including food, water, refuge, and safety. When an animal's habitat is disturbed, it is forced to migrate in quest of sustenance, water, shelter, and safety. In due time, other animals may attack the animals.
the top layer of soil is exposed
The deeper soil layers become progressively visible as the upper soil layer is removed. Lower dirt levels are less fruitful because they are rocky and hard in character. This is as a result of the decreased soil content. Continued soil loss will result in barren, infertile territory.
5. Answer in Brief
a) Why should we conserve biodiversity?
b) Protected forests are also not completely safe for wild animals. Why?
c) Some tribal depend on the jungle. How?
d) What are the causes and consequences of deforestation?
e) What is Red Data Book?
f) What do you understand by the term migration?
Explanation:
a. Biodiversity refers to the quantity and range of different living forms, such as plants, animals, and microbes, in a region. For their existence, both plants and creatures are reliant on one another. Because they are interconnected, if one is destroyed, the other will follow suit. Therefore, biodiversity needs to be protected in order to keep the equilibrium of environment.
b. For their daily requirements, people who reside close to forests rely on the resources of the forests. Animals residing in protected woodlands are therefore not secure. The existence of humans would pose a danger to the animals. As a consequence, wild creatures are killed and their products are sold for enormous amounts of money.
c. Forest products are heavily consumed by tribes that reside close or in forested regions. They chase creatures for sustenance, and they burn firewood for cooking. They use a variety of vegetation for sustenance, fibre, herbs, and medications. The jungle plays a significant role in tribal life, from food gathering to building homes and other buildings out of bamboo or wood. They have employment opportunities in tree harvesting, plantation development, collecting, and processing of forest goods. They collect fresh produce and clean water from the jungle.
d. Deforestation's Causes
Deforestation has many different reasons. We've enumerated a few of them below.
Forest areas are frequently cleared and turned into lands for different purposes in order to support the rapidly growing metropolitan population.
Forest areas are cleared for farming uses like grain planting and livestock grazing.
One of the primary justifications for widespread tree cutting is the production of firewood, a significant product from the woods.
Consequences of destruction
The destruction of forests has many deadly effects. We've enumerated a few of them below.
eroding soil
variety loss
Floods
Droughts
Climate change has caused global warming.
The Red Data Book is a reference work that contains a global inventory of all plant and animal species that are in peril of going extinct. By performing a thorough study, the International Union for Conservation of Nature and Natural Resources (IUCN) updates the books and adds/removes the names of the species.
Migration is the regular, predictable movement of an organism or a collection of organisms from one location to another at a specific period each and every year. The organisms take this action to escape unfavourable climatic circumstances or for the purpose of reproduction.
6. In order to meet the ever-increasing demand in factories and for shelter, trees are continually being cut. Is it justified to cut trees for such projects? Discuss and prepare a brief report.
Explanation:
No. It is not at all justified to cut down forests to satisfy the increasing needs of the human populace. The woods are home to a wide variety of creatures, including insects, birds, and wild animals. Animals, birds, people, and other living things can all breathe clean oxygen thanks to the forests. This is because plants breathe through a process called respiration, which allows them to take in toxic carbon dioxide and release high-quality oxygen. As a result, they control carbon emissions and global warming. Soil erosion can be stopped by the roots of the woodland vegetation. They could also help to avoid natural disasters like storms and droughts. They aid in boosting soil productivity and preserving the ecosystem's variety.
In order to meet the needs of the ever-growing human population, forests and their resources are overused by cutting a lot of trees, which causes many long-term issues like:
Soil erosion
Greenhouse effect
Global warming
Floods
Droughts
In addition to the issues mentioned above, widespread destruction will have an enduring impact on human civilization. The removal of forests upsets the harmony of the environment. Therefore, protecting woodlands should be a top concern.
7. How can you contribute to the maintenance of the green wealth of your locality? Make a list of actions to be taken by you
Explanation:
I can protect my community's natural resources by cultivating vegetation there. By raising consciousness of the value of plant life in an ecosystem, I will inspire the residents of my neighbourhood to grow more trees and care for the ones that already exist. I would start the process and plan weekly meetings on the subject to make this feasible. It would be of the utmost importance to raise consciousness among children and young people, as they will be better able to comprehend the problems we are confronting. As essential as maintaining current trees is planting new ones. So I would regularly water the vegetation and trees with the help of my helpers.
8. Explain how deforestation leads to reduced rainfall.
Explanation:
Deforestation is the removal of trees and other plant life from a specific region for the development of industries, farms, and other uses. The process of photosynthesis in plants involves the uptake of CO2 from the environment. When plants are killed, the amount of carbon dioxide in the atmosphere rises sharply, creating a heat emission trap that contributes to global warming. The water cycle will be impacted by this temperature increase. When the water cycle is disturbed, a series of things happen, and eventually the rhythm of rainfall alters and there are droughts.
9. Find out about national parks in your state. Identify and show their location on the outline map of India.
Explanation:
Pericarp National Park, located in the state of Kerala.
10. Why should the paper be saved? Prepare a list of ways by which you can save paper.
Explanation:
17 fully mature trees must be felled in order to create one ton of clean, white paper. The equilibrium of environment is greatly influenced by trees. Therefore, it is crucial to conserve paper in order to safeguard forests and lessen the effect that their loss will have on the living things that rely on them.
Methods for preserving paper
Paper waste collection and disposal.
Penmanship on a piece of paper's both surfaces.
Educating young people and schoolchildren about the value of paper.
Wise and appropriate use of paper.
