What prediction is correct about island biogeography?

• Smaller islands have more resources, and will have more biodiversity

• Larger islands have more space for resources, but will have less biodiversity due to competition

• Animals Islands closer to mainland will migrate successfully and there will be more diversity

• Animals will fly to far away mainland and there will be more diversity

• Demographic bottleneck

• Island biogeography

Which is NOT a factor in the theory of island biogeography?

• Islands farther from the continent have more species due to increased speciation
• dispersing species are more likely to find a large habitat
• islands can also be isolated areas within a continent
• larger habitats contain a larger range of environmental conditions

Which of the following is true about island biodiversity?

• Small islands are more likely to have more immigrated species

• Small islands have higher biodiversity than large islands

• Small islands have more resources and as a result may have more species

• Small islands have fewer resources and as a result may have fewer species

Which of these ecosystems would be most likely to recover?

• a temperate forest with average biodiversity that loses many types of trees due to a fire

• a tropical rainforest with high biodiversity that loses a species of fig tree due to a type of fungus

• a desert that has low biodiversity and loses all of the saguaro cacti that are growing there

All of the following statements concerning characteristics of predator-prey relationship are correct EXCEPT:

• Camouflage is an adaptation that protects prey.
• A rise in the population of predators is followed by a decreased in the population of prey.
• A rise in the population of prey is often followed by a rise in the population of predators.
• The population of predators most often eliminates the population of prey
