Question

Triggerfish gain energy by eating crabs.

How much of this energy can be transferred up the food chain to sharks?

A) Only the energy used for cellular respiration
B) Only the energy stored in body tissues
C) Only the energy converted into heat

Answer 1

I think b is the correct option

Answer 2

A) Only the energy used for cellular respiration can be transferred up the food chain to sharks.

Explanation:

• Through the food chain, energy is exchanged between organisms. Producers are at the start of the food chain. Primary consumers consume them, which are then consumed by secondary consumers.
• They are then consumed by tertiary consumers and in the case of a long food day, quaternary consumers.
• When an organism breaks down food, the energy necessary to hold these molecules together is released. The energy is subsequently used by cells to accomplish tasks such as cellular respiration.
• Glucose is broken down in the presence of oxygen to produce carbon dioxide and water during cellular respiration. The energy-carrying molecule ATP (adenosine triphosphate) captures the energy generated during the process.
