Humans and human impacts affect natural resources in various ways. Which of the following is a primary effect?

• Depletion of resources

• Increase in biodiversity

• Stabilization of ecosystems

• Reduction in pollution

One effect invasive species have on native environments is:

• They increase biodiversity.

• They often outcompete native species.

• They improve soil quality.

• They have no impact.

Define “carrying capacity”?

• The maximum population size of a species that an environment can sustain

• The minimum population size of a species that an environment can sustain

• The total population size of all species that an environment can sustain indefinitely

One effect of what happens to an ecosystem and/or environment when carrying capacity is reached is:

• Increased biodiversity

• Population decline

• Unlimited resources

• Stable population growth
