There are many advantages to high biodiversity. Which advantage do organisms depend on most to increase the chance of survival of their species?

• High biodiversity allows natural selection to occur

• High biodiversity increases the chances in survival of a species

• High biodiversity allows only a few species to survive

• High biodiversity maintains nutrient cycles and air and water quality

Which of the following is an example of a structural adaptation in plants?

• Thorns on a cactus

• Photosynthesis

• Pollination by bees

• Seed dispersal by wind

How does camouflage benefit an animal in its natural habitat?

• It helps the animal find food more easily
