Question

Show the relation between the biotic and abiotic components of the environment with the help of a diagram.

Answer 1

The relation between the biotic and abiotic components of the environment.

• The abiotic substances supply nutrients to the producers.
• The producers prepare food for the consumers.
• Both producers and the consumers, after death are broken down into simpler substances by the decomposers.
• The nutrients and the minerals are replenished in the soil (air, water also).
• The nutrients and the minerals are again used by the producers and the whole cycle is repeated continuously.
• This cycling of materials through biotic and abiotic components is called the mineral cycle.

Meanings of the words :-

Abiotic : The non living things like air, water, soil, light etc.

Biotic : The living things like plants, animals, humans etc.

Producers : The living things that used to produce their own food. Also called autotrophs. Examples - green plants

Consumers : The living things, who used to depend on the producers

• Primary consumers : eats only plants. Examples - cows, goats etc.
• Secondary consumers : eats the primary consumers. Examples - lions, tigers etc.
