Intrinsic and environmental factors affecting the population size.
Explanation:
Size of any population is determined by Intrinsic and environmental factors. Population size of any species is regulated by the factors such as death rate, birth rate, carrying capacity of the system, limiting factors and their availability, rate of migration etc. All these factors should considered to predict changes to a population of rabbits in in a meadow.
It should include the species of a rabbit. There are multiple types of rabbit and that would be considered the independent variable (where there are different things).
It should aloso include the environment; Are rabbits comfortable living in hot or cold weather areas?
