Question
Which of the following are autotrophs in an
ecosystem?Solution
Autotrophs are organisms capable of producing their own food through photosynthesis (using light energy) or chemosynthesis (using chemical energy). Plants are primary autotrophs that convert sunlight, carbon dioxide, and water into glucose and oxygen through photosynthesis. As primary producers in food chains, they support all other organisms in the ecosystem. Fishes and earthworms are heterotrophs that consume other organisms for energy, while sunlight is not an organism but an energy source used by autotrophs.
