Question

question 1 - 2
how does the second law of thermodynamics apply to energy flow in a food web?
organisms at higher trophic levels receive the same amount of energy as those at lower levels due to energy recycling
as energy moves through the food web, a portion is always lost as heat, increasing the entropy of the system
energy is conserved and remains constant across all trophic levels in a food web
energy is destroyed as it moves through the food web, leading to a decrease in available energy at higher trophic levels

Explanation:

The second law of thermodynamics states that entropy (a measure of disorder) in an isolated system always increases over time. In a food - web, as energy moves from one trophic level to another, some energy is lost as heat, which increases the entropy of the system. Organisms at higher trophic levels receive less energy than those at lower levels (not the same amount), energy is not conserved in the sense that some is lost as heat (it's not constant across trophic levels), and energy is not destroyed but transformed with some loss as heat.

Answer:

As energy moves through the food web, a portion is always lost as heat, increasing the entropy of the system.
