Chapter-1 Environment

Explanation:

The system created by interactions between all living things and the physical and chemical components of their environment—all connected by the exchange of material and energy—is what is referred to as an ecosystem.

Explanation:

The natural environment is made up of the fundamental elements and living things that exist in the world on their own, without from human interference, such as the land, the water, the air, the plants, and the animals.

Explanation:

Natural Ingredients (Air, Water, Land and Living things)

Components developed by people (Components created by human beings)

Human Constituents (Human populations).

Explanation:

Structures, parks, businesses, and bridges are four examples of the human-made environment.

Explanation:

The solid crust, also known as the earth's hard outer layer, is referred to as the lithosphere. It is made of rocks and minerals, and a thin layer of dirt covers it. Its landscape is diverse, with mountains, plateaus, plains, and other formations.

Explanation:

The biotic environment is mostly composed of plants and animals.

Explanation:

The biosphere, often known as the living world, is the little area of the earth where air, water, and land interact to support life. The biosphere is made up of the kingdoms of plants and animals.

Out of all the given options, the correct answer is Aquarium. Even though an aquarium is a functioning ecosystem, it is not a natural ecosystem. It is an artificial ecosystem. This is because humans add all the components in the Aquarium like plants, fishes, rocks, water, and others, so it falls in the category of an artificial ecosystem. 

The remaining options, (1) Desert and (3) Forest, are examples of a natural ecosystem. There is no direct involvement of man in their creation. They are formed naturally over time. Their existence is entirely natural and self-dependent by all means.

Explanation:

 (a)

The land is the natural component whereas the other is the human environment. The basic components and organisms that are naturally present in the environment without any human involvement, like the land, water, air, plants and animals comprise the natural environment.

Components of environment

Components of the environment include:

Natural Components (Air, Water, Land & Living things)

Human Made Components (components created by human beings)

Human Components (human populations)

The land is not a part of the human environment. The social condition is the human environment, together with the external factors that physically and naturally influence a person. Where religion and community will directly impact a person. External factors involve biological, aesthetic, social, ecological, economic, cultural, historical factors, and so on., that would have a bigger impact on an individual’s lifestyle.

Explanation:

( b )

The surroundings is the conditions in which a person, animal, or plant lives or operates.

The environment can be man-made or natural

Man-made are those which have human efforts in their making.

Natural are those which don't have human effort in their making.

In the making of mountains and sea human effort is not involved.

In the making of roads, human efforts are involved.

The human population refers to the number of individuals in a particular area. Human population growth is the increase in the number of individuals in a particular area. Changes in public health and sanitation have led to a decrease in the death rate over the past 200 years.

As the rising population puts a lot of pressure on the planet and the climate, the growing population is a danger to the ecosystem.

Artificial and chemical methods are being used to produce more food farming in order to feed the growing population.

Establishment of industry that increases environmental pollution, unhealthy lives, due to the rising rate of garbage, several diseases prevail.

The rising population is contributing to global warming. Furthermore, global warming contributes to climate change, like growing temperatures, low rainfall levels, melting glaciers, and so on.
