Explanation:

To solve these questions, we analyze each based on ecological concepts (trophic levels, food pyramids, decomposers, energy transfer, etc.):

Question 1

The Everglades ecosystem’s key lesson from the video (likely about trophic balance) – Option c (importance of decomposers) or other options? Wait, the Everglades’ ecosystem dynamics: decomposers recycle nutrients. But let’s check:

• a) Plants’ dominance is not the main lesson.
• b) Alligators as top predators – but the question is “most important learning.”
• c) Decomposers’ role in food pyramid (recycling) is critical.
• d) Variety of habitats – not the core lesson.

Answer:

c) The importance of decomposers in the food pyramid

Question 2

Key moments/ideas in the video (trophic levels, decomposers, predator roles, etc.):

• a) Abundance of plants/herbivores – not the key.
• b) Predators maintaining ecosystem – possible, but let’s check others.
• c) Trophic levels in food pyramid – core concept.
• d) Decomposers recycling organic waste – also core. Wait, the video title is “Trophic Levels and Food Pyramids.” So Option c (trophic levels) or d? Let’s assume the video highlights trophic levels.
