What effect does biodiversity have on a community?

• It makes destruction by insects impossible. 
• It makes primary succession more likely.   
•  It enables species to survive in a desert.
• It enables the community to withstand changes.

The ecological niches of three bird species are shown in the diagram. What is the advantage of each bird species having a different niche?

• As more birds feed higher in the tree, available energy increases.
• More abiotic resources are available for each bird.
• Predators are less likely to feed on birds in a variety of locations.
• There is less competition for food.

What is a keystone species?

• A species that helps to hold an ecosystem together
