1.The recycling of papers contributes to forest preservation. Justify.
Explanation:
The papers are created from wood pulp, to be precise. We hacked down trees to get wood. We can stop harvesting forest trees for fresh raw materials needed to make paper if we recycle the existing stock of paper on the market and don't let it disintegrate.A tree takes years to grow, yet it just takes a few minutes to cut one down. Thus, we should think carefully before chopping down even one tree, and we should promote paper recycling all across the world.
2.The resources in forests are valuable. Explain.
2.The resources in forests are valuable. Explain.
Explanation:
The use of forest products is essential for socioeconomic growth. We receive food (cereals, pulses, fruits), firewood, fibre, building supplies, industrial goods (tannins, lubricants, dyes, resins, and perfumes), as well as goods of significant medical value. The ecology is maintained by the various animals that calls it home. As a result, forests are important resources.
3.The O2-CO2 cycle is maintained in part by plants. In light of photosynthesis and respiration, explain it.
3.The O2-CO2 cycle is maintained in part by plants. In light of photosynthesis and respiration, explain it.
Explanation:
The process by which plants utilise CO2 and release O2 as a byproduct is called photosynthesis. Animals use this O2 for respiration, while plants use the CO2 that is generated during this process for photosynthesis. Plants balance the O2-CO2 cycle in this way.
4.The producers of a food chain are referred to as plants. cite an example.
4.The producers of a food chain are referred to as plants. cite an example.
Explanation:
The producers of a food chain are referred to as plants. It is because all living things that inhabit the forest depend on green plants, or "autotrophs," which produce their own sustenance from carbon dioxide and water in the presence of sunshine and chlorophyll.
5.Without plants, life could not exist. Describe how.
5.Without plants, life could not exist. Describe how.
Explanation:
All green plants are producers, to be precise. Using water, CO2, and sunlight, they carry out the process of photosynthesis to produce food. Animals of all kinds rely on plants for nourishment. So, if there are no plants, there will be no food. In order for plants to produce oxygen during photosynthesis, there must be a plant present. We cannot imagine living without plants because of these two fundamental demands that plants fulfil for humans.
6.Creating a food chain without a producer is it possible? Provide a justification for your response.
6.Creating a food chain without a producer is it possible? Provide a justification for your response.
Explanation:
No, the producers are always at the top of any food chain. Every living thing has nourishment because of the producer. If a producer is not present in a food chain, energy will not flow. So, we might conclude that a food chain cannot be created without a producer.
7.How is it possible that a pipal sapling would have risen on the side wall of such antique structures?
7.How is it possible that a pipal sapling would have risen on the side wall of such antique structures?
Explanation:
Animals use their droppings to spread the seeds of some plants. Hence, a bird's dropping of pipal seed would have brought it to the wall. It would have developed into a pipal sapling if it had come into contact with water and an appropriate nutrient media.

Answer:
9.In a forest, nothing is wasted, so the saying goes. Please elaborate on how.
9.In a forest, nothing is wasted, so the saying goes. Please elaborate on how.
Explanation:
Because of the following factors, nothing in a forest is wasted. A dark-colored substance known as humus is created from dry leaves and animal remnants. The plants receive nutrients from this. Vultures, ravens, jackals, and insects eat dead animals. The locals who reside close to the forest burn broken tree branches as fuel.
10."Forest is a dynamic, vibrant, and alive organism." Justify short.
10."Forest is a dynamic, vibrant, and alive organism." Justify short.
Explanation:
The answer is that forests are home to a wide range of flora and animals. Herbivores get their nourishment from plants. A greater diversity of carnivores can eat more since there are more herbivores. Animal diversity promotes forest regeneration.
Cleaning agents include decomposers and scavengers. As a result, each and every organism in the forest contributes significantly to its energy and active life.
11.List the key measures we can take to preserve the forest.
11.List the key measures we can take to preserve the forest.
Explanation:
In nature, forests preserve harmony. Conservation is urgently needed there. To protect the forests, we should take the following actions.
Intended harvesting Cutting only a portion of the trees in an area is an effective approach to efficiently obtain wood from forests for our needs. Erosion is avoided by the uncut trees. These trees' fruits provide seeds that allow new trees to sprout. In this manner, the forest cover is preserved.
(ii) Forestry damage By putting down seedlings or young trees, a forest is being renewed in this manner. Planned afforestation is now carried out in our nation for economic gain by both the government and private organisations. In these plantations, selective tree cutting maintains the forest cover while simultaneously providing timber for construction and Protection against fire .
(iii) Every year, large portions of forests are devastated by fire. People's negligence, lightning during a storm, or friction between dry tree stems and dry branches are all potential causes of fire. Forest fires can be put out by using strong blowers to change the wind's direction or by spraying fire retardant chemicals from helicopters.

16.What transpires if an animal perishes in a forest?
16.What transpires if an animal perishes in a forest?
Explanation:
Scavengers like jackals, hyanas, and vultures consume the dead animal's body.
These creatures do cleaning duties in the woodland. Furthermore, it demonstrates that in the forests, nothing is wasted.
17.What makes woodlands known as "green lungs"?
17.What makes woodlands known as "green lungs"?
Explanation:
The photosynthetic mechanism used by forest plants to create oxygen. And plants give this oxygen to animals so they can breathe. They also regulate the oxygen to carbon dioxide ratio in the atmosphere. The woodlands are referred to as the "green lungs" because of this.
18.Why are woods thought of as living, dynamic things?
18.Why are woods thought of as living, dynamic things?
Explanation:
By supporting a greater variety of plants, the forest provides more chances for food and habitat for herbivores. Because there are more herbivores, a wider variety of carnivores can consume more food. The profusion of animals encourages the forest's expansion and renewal. Decomposers help to maintain the supply of nutrients to the growing plant life in the forest. The forest is thus a "dynamic living creature," or one that is brimming with life and vitality.
19.List the most important safeguards we can implement for the forest.
19.List the most important safeguards we can implement for the forest.
Explanation:
The balance of nature is maintained by forests. It is vital that they be conserved. We should take the following actions to protect the forests:
Alarming numbers of trees were being cut down for raw resources and other purposes as industrialization developed. Controlling this tree-felling can be done through selective cutting, clear-cutting, and cutting for shelterwood.
More trees should be planted in order to improve the forest cover. When selecting trees, one should take into account the local climate, and as they mature, one should use caution.
Preventing the exploitation of forestry and forest products is crucial for the preservation of the forest.
20.Why are woods worth protecting?
20.Why are woods worth protecting?
Explanation:
The answer is that forests give us oxygen. They shield the soil and give a variety of creatures a place to live. Good rainfall is a result of forests in the surrounding areas. They offer lumber, timber products, medicinal herbs, and many other valuable things. As a result, forests need to be safeguarded.
