Question

Producers in an ecosystem are

• A. Organisms that can be used as manures
• B. Animals in the food chain which produce more energy than they consume
• C. Animals which cause an increase in biomass by rapid multiplication
• D. Green organisms which fix solar energy by photosynthesis

Answer 1

The correct option is D Green organisms which fix solar energy by photosynthesis

Producers, consumers, and decomposers are all interrelated in food chains and food webs and dependent on one another for survival. Producers make their own food. They do not have to obtain energy from other organisms. They obtain their energy from the sun and make food with that energy through the process of photosynthesis. They are also called autotrophs and are at the beginning of any simple food chain.

So the correct option is 'green organisms which fix solar energy by photosynthesis'.
