APES Unit 2 Review

Front

What is carrying capacity?

Back

The maximum population size of a species that an environment can sustain indefinitely without being degraded.

Front

What type of ecosystem service is provided by bees pollinating crops?

Back

Supporting ecosystem service.

Front

What is a population's zone of intolerance?

Back

The range where organisms will die due to unfavorable environmental conditions.

Front

How do you calculate Net Primary Productivity (NPP)?

Back

NPP = Gross Primary Productivity (GPP) - Respiration (R).

Front

What type of ecosystem service is obtaining lumber from a forest?

Back

Provisioning ecosystem service.

Front

Define Gross Primary Productivity (GPP).

Back

The total amount of carbon fixed by photosynthesis in a given area and time.

Front

What is Net Primary Productivity (NPP)?

Back

The rate at which all the plants in an ecosystem produce net useful chemical energy; NPP = GPP - R.

Front

What are ecosystem services?

Back

Benefits provided by ecosystems to humans, including provisioning, regulating, supporting, and cultural services.

Front

What is an example of a regulating ecosystem service?

Back

Climate regulation, such as carbon sequestration by forests.

Front

What is the difference between provisioning and supporting services?

Back

Provisioning services provide direct benefits (like food and water), while supporting services maintain the conditions for life (like nutrient cycling).
