Question

According to Lindeman's 10% law, what amount of energy will be present at the level of primary consumers if the plants produce 4,000 kcal of energy?

• A. 40,000 kcal
• B. 4,000 kcal
• C. 400 kcal
• D. 40 kcal
• E. 4kcal

Answer 1

The correct option is C 400 kcal

In the ecosystem, energy flow, also called the calorific flow, refers to the flow of energy through a food chain and a unidirectional. Only 10% of the energy is passed on from one trophic level to successive trophic level and each time about 90% of the energy is lost as heat into the environment by metabolic activity. At the level of primary consumers, they will have 400 kcal of energy if the plants produce 4,000 kcal of energy.
