How parasitism differs from a predator prey relationship.
What is parasitism one organisms lives off the other whereas in pred/prey one is killed and eaten?

100
5 major abiotic factors
What are air, sunlight, climate, precipitation and soil?
200
The difference between an ecosystem and a community.
What is an ecosystem has abiotic and biotic factors whereas a community only has biotic factors
200
food, space, shelter and water
What are limiting factors?
200
Both organisms benefit.
What is mutualism?
200
The base of the food chain or energy pyramid and why.
What are producers because they are only organisms that can take the energy of the sun and turn it into food?
200
percent of nitrogen in the air
What is 78%
300
The difference between a community and a population.
What is a community contains all the biotic factors whereas the population is only about one species.
300

What is a low biotic potential = moose and high = fish
