• D. A - consumers, B - reducers, C - decomposers

Answer 1

The correct option is A A - producers, B - consumers, C - decomposers

An ecosystem is a self-sustained stable unit formed by the interactions between the biotic (living) and abiotic (non-living) factors that are comprised in it.

Components of the ecosystem

The biotic components include:

• Producers (autotrophs): They are able to synthesise organic matter from inorganic materials with the help of solar energy through the process of photosynthesis. Examples include green plants, cyanobacteria etc.
• Consumers (heterotrophs): These organisms depend on other organisms for food. Examples include herbivores (feed on plant matter), carnivores (feed on animal matter) etc.
• Decomposers (saprotrophs): Decomposers or reducers are saprophytic organisms which obtain their nourishment from the dead and decaying organic matter. Examples include bacteria, fungi etc.
