what percentage of energy is lost between trophic levels in a food chain?
50%
10%
90%
80%

Explanation:

Question 2

• Option 1: Studies molecular interactions (chemistry - related, not ecology).
• Option 2: Ecology studies organisms' interactions with each other and environment.
• Option 3: Focuses on energy transfer (more like energetics, not ecology's core).
• Option 4: Study of living things is biology, not specific to ecology.

The 10% energy transfer rule (only ~10% energy moves to next trophic level, so ~90% is lost as heat, waste, etc.).

Answer:

B. The study of interactions of living organisms with one another and their environment.
