Which of the following resources can be in limited supply in an ecosystem?

Food, sunlight, water, oxygen and shelter :3

Explanation:

As a growing population reaches the limits of the available resources in an environment, its size levels off to "match" the amount of resources available. In doing so, the population reaches its carrying capacity.

Another factor that affects the carrying capacity of an ecosystem is the rate at which decomposers can break down the remains of dead organisms within the ecosystem. The faster an ecosystem can recycle the nutrients in dead organic matter, the larger the populations it sustains can become.
