Answer:

1. A population of 300 deer will remain at about 300

2. community

3. amount of sunlight

Explanation:

1. Carrying capacity is defined as the maximum population size of a biological species that can be sustained by that specific environment, given the food, habitat, water, and other resources available. Therefore if a population has reached its carrying capacity, it will most likely remain at that size.

2. A community is defined as all of the populations of different species that live in the same area and interact with one another. Clownfish, seahorses, and sea grass are all different species living in an area together and interacting with each other. This example does not show a population, nor a species, nor biome, since a population is a group of organisms of the same species, and a biome is a distinct biological community that has formed in reponse to a shared physical climate.

3. Abiotic factors are non-living factors which affect an ecosystem.
