Multiple Choice

What is the difference between Trophic Levels and Niches?

• Niches only refer to the physical environment of an organism.
• Trophic levels indicate energy flow in food chains, while niches describe an organism's role in its ecosystem.
• Trophic levels are the same as niches.
• Trophic levels describe the habitat of an organism.
