Question

To characterise the habitat of an organism both biotic and abiotic components play an important role which includes

• A. physico-chemical factors as both abiotic and biotic components
• B. pathogens and parasites as biotic components and decomposers and competitors as abiotic components
• C. pathogens and parasites as biotic components and physico-chemical factors as abiotic components
• D. physico-chemical factors as biotic components and pathogens and parasites as abiotic components

Answer 1

The correct option is C pathogens and parasites as biotic components and physico-chemical factors as abiotic components

Habitat is a place where an organism lives. It is like a home for the organism where all the favourable environmental conditions are met for its survival.

For the survival of the organisms both biotic and abiotic components in a habitat are important.

Biotic (living) components: These include any living organism that is present in an ecosystem such as plants, fishes, animals, microbes, parasites, predators, pathogens and even competitors.

Abiotic (non-living) components: These include the physical (temperature, water, light) and chemical (levels of oxygen, nutrients) factors present in the environment of the organisms.

Therefore, parasites and predators are biotic components and physico-chemical factors are the abiotic components in a habitat. ‌
