What creates an environment where organisms can survive?
Where does a k-selected species thrive?
What type of species has an unstable environment, high fecundity, small in size, early breeding, short generation time, low parental care and grows exponentially?
What type of interaction is predation?
What are rates of extinction like on islands far from mainlands?

What type of selection is density independent?
What type of species follow the survivorship 1 curve?

About how much energy is transferred from one trophic level to another through feeding interactions?
Webster (1994) discovered that rats infected with Toxoplasma gondii no longer fear the smell of cats. Cats are the final host for T. gondii. This is an example of a parasite altering host behavior to
Gross primary productivity is higher than net primary productivity. The difference between the two is
With the addition of resource limitation, what change do you expect in the number of births as population size increases? In the number of deaths?
A population of penguins has an annual per capita birth rate of 0.08 and an annual per capita death rate of 0.1. Estimate the net gain or loss of individuals from a population of 1,000 penguins in one year.
What happens in a community when two species directly compete for a limited resource?
Which interaction reduces fitness for both species involved?
You observe two female fish. One female lays 100 eggs and the other female lays 1000 eggs. Consider the concept of fitness trade-offs. Compared to the female laying 1000 eggs, the female laying 100 eggs should
