Answer 1

The correct option is B autotrophic component

Ecosystem is a functional unit of nature where living organisms interact among themselves and with their physical environment.

A pond ecosystem is an aquatic ecosystem. Water, soil deposited at the bottom of the pond, sunlight, etc. are the abiotic components of the pond ecosystem. The biotic components of the pond include the producers, consumers and decomposers. Phytoplanktons, some algae, floating plants, submerged plants, plants found at the edges of the pond are the autotrophic components i.e the producers. Zooplanktons, free swimming and the bottom dwelling animals represent consumers. Fungi and bacteria, which are abundant at the bottom of the pond, are the decomposers.
