Question

4 which combination is the main source of ecosystem disruption? a migration and adaptation b balance and imbalance c human and natural d predator and prey

Explanation:

To determine the main source of ecosystem disruption, we analyze each option:

• Option A: Migration and adaptation are natural processes that help species survive and usually don't disrupt ecosystems but rather help them adjust.
• Option B: Balance and imbalance are states, not sources of disruption. Imbalance is a result, not a source.
• Option C: Human activities (like deforestation, pollution) and natural events (like earthquakes, volcanic eruptions) are major sources of ecosystem disruption as they can alter habitats, food chains, and resource availability.
• Option D: Predator - prey relationships are a natural part of ecosystems and help maintain balance, not disrupt it.

Answer:

C. human and natural
