What role do liana vines play in the Amazon rainforest?

• Absorbing water from the soil

• Blocking sunlight to the forest floor

• Providing shelter for predators

• Supporting trees and aiding herbivores

What happens when a species with a weakened gene pool disappears?

• The ecosystem becomes more resilient

• The climate of the area improves

• New species quickly evolve to fill the gap

• Parts of the ecosystem's net disintegrate

Why are coral reefs considered dependent on corals?

• Corals supply the majority of oxygen in the water

• Corals provide essential habitats and breeding grounds

• Corals control the water temperature

• Corals prevent ocean acidification
