Question

How are changes in populations related to the availability of an ecosystem's resources?
As populations grow, ecosystems produce more resources in order to support the larger population.

Population sizes are limited by the amount of resources that are available.

Changes in population are independent of the availability of an ecosystem's resources.

Large populations need the same amount of resources as small populations.
