The carrying capacity of an ecosystem is the size of a population that can be supported indefinitely by the available resources of that ecosystem. The carrying capacity of an ecosystem is affected by interactions among organisms and available resources.

The limits of an ecosystem depends on three factors:
1. The amount of resources available in the ecosystem.
2. The size of the population.
3. The amount of resources each individual is consuming.

Describe how the carrying capacity of an ecosystem is affected by predator-prey and competition interaction among organism in terms of the three factors listed above.
