उत्तर
CO2 in atmosphere → organic carbon in plants → organic carbon in animals → inorganic carbon in soil
Explanation:
Carbon is present as a combined state in the atmosphere in the form of carbon dioxide. This C02 from the atmosphere is incorporated into life forms through the basic process of photosynthesis. This process converts carbon dioxide into glucose molecules (organic carbon in plants). Animals feed on the plants and utilise the glucose molecules to release C02 and energy (organic carbon in animals). The dead plants and animals are then consumed by decomposers and made available as fossil fuel and humus (inorganic carbon in soil).

Name the following:
The layer of atmosphere which contains the ozone layer.
We often leave the lights switched on and fans running when we are not in the room. We switch on the air-conditioning even though we don’t really need it. We insist on being dropped to school in the car every day. Thus, we waste valuable energy which is generally produced by burning coal and petroleum. As you know, the burning of these fuels release gases that pollute the atmosphere.
Make a list of the similar things that we do without realizing that we are destroying the environment. Think of the ways that we can behave differently.
