Question

Quizplus · Accepted Answer

Since there is no mention of any process that involves the conversion of light energy into chemical energy, it is safe to assume that there is no photosynthesis taking place in this ecosystem.

Answer: B
 The statement "no energy is transferred between trophic levels" is not possible in any ecosystem. This choice can be eliminated.

Answer: C
 While temperature is an important abiotic factor, it cannot be the most important biotic factor as the question specifies.

Answer: D 
 This choice is not possible as the definition of producers and consumers is based on whether they produce or consume organic compounds directly or indirectly. So, producers cannot eat consumers.
