Question

Energy flow in an ecosystem begins with ______.

Options

• omnivores

• herbivores

• decomposers

• autotrophs

Answer 1

Energy flow in an ecosystem begins with autotrophs.

Explanation:

Energy flow in an ecosystem begins with autotrophs (producers), which capture solar energy through photosynthesis and convert it into chemical energy in the form of food. This energy is then transferred to other organisms in the food chain. Thus, autotrophs serve as the primary source of energy for all other organisms in the ecosystem, initiating the flow of energy.
