Ecosystem Components and Food Chains Quiz

Nutrient recycling prevents energy loss in food chains.

Nutrient recycling ensures a constant supply of energy in the ecosystem.

Nutrient recycling is responsible for the unidirectional flow of energy in ecosystems.

Nutrient recycling involves the continuous reuse of nutrients by living organisms. (correct)

A food chain represents a single pathway of energy flow, while a food web consists of multiple interconnected food chains. (correct)

A food chain includes decomposers, while a food web does not.

A food chain is more complex than a food web.

A food web illustrates trophic levels better than a food chain.

Energy is lost as heat at each trophic level, preventing its reuse.

Energy is recycled by producers for their own use, leaving less for consumers.

Energy is constantly replenished by the sun, allowing it to flow unidirectionally through trophic levels. (correct)

Energy is stored within organisms and cannot be reused by others.
