DOK Level 2: Skill/Concept

Why is it important for an ecosystem to have a variety of different food chains and not just one?

• It ensures more energy is available at each trophic level

• It prevents any single species from becoming too dominant

• It provides multiple pathways for energy flow and increases ecosystem stability

• It makes the ecosystem less complex and easier to study
