A food web is a diagram that shows the interaction of organisms in an ecosystem.
Which statement best describes the transfer of energy in a food web?

(3) Energy from the sun is stored in green

plants and transferred to consumers.

Explanation:

(1) Energy is transferred to consumers, which

convert it to nitrogen and use it to make amino acids.

(2) Energy from producers is converted into oxygen and transferred to consumers.

(3) Energy from the sun is stored in green

plants and transferred to consumers.

(4) Energy is transferred to consumers, which use it to produce food.

The statement that best describes the transfer of energy in a food web would be that energy from the sun is stored in green plants and transferred to consumers.

There are three levels of organisms in food webs.

The producers directly produce their own foods through photosynthesis during which energy from the sun is used to produced foods and stored in green plants. The energy locked in this food is transferred to consumers that directly or indirectly feed on the green plants. Without the producers, the food web will cease to occur.

Hence, the correct option is (3). All the remaining options are deficient/untrue to a varying degree.
