Answer:
A. amount of food available
Explanation:
An experiment consists of two types of variables, independent and dependent. Value of independent variable is decided by the person doing the experiment and is independent of experimental conditions. Value of dependent variable is dependent on the independent variable. It can not be altered by the person doing experiment.
Here, it is given that mice receive variable amount of food each day and their lifespan is recorded. Since the amount of food is decided already it is the independent variable. The lifespan is expected to depend on the amount of food hence it is the dependent variable.
The question is assuming that the coyotes are the only predators (hence <em>eliminating</em> <em>all </em><em>predators of the rabbit</em>).
What would happen is that the rabbit population would continue to thrive throughout the years, until the producers cannot support the rabbits, leading to a mass extinction of the rabbits and the destruction of the ecosystem that used to be there.
The statements that are true of logistic growth are A) as the population becomes larger, it grows more slowly, and B) when the population reaches carrying capacity, it stops growing.
