• runoff

• recharge

What does biodiversity mean?

• The different amount of species in an area

• All abiotic life

Scientists are concerned about overfishing of shark populations. Sharks feed on rays and rays feed on scallops. Without sharks, rays consume all the scallop beds. This situation demonstrates that:

• humans can improve an ecosystem by removing predators.

• humans can upset an ecosystem by removing species.

• reducing the shark population increases the quantity of scallops that can be taken.

Which of the following describes a negative consequence of commercial fishing?

• Removal of invasive species

• Ocean food webs become imbalanced

• Increased dissolved oxygen concentration

Fish in a small pond will most likely depend on which of the following biotic factors to meet their needs?

• Plants that exchange gasses with the pond water.

• Insects that feed on other insects in the pond.

• Water birds that prey on amphibians and small fish.

The gradual process by which ecosystems change and develop over time. Nothing remains the same and habitats are constantly changing.

• Ecological Succession

• Ecology Success
