What is Parasitism?
Use the following food chain:
Plant>Frog>Snake>Hawk

Plants will overgrow and snake population will go down
What is a population?

What are decomposers
Fighting over mates is an example of
What is competition?
Both species benefit
What is Mutualism?
Lightning from a thunderstorm strikes a tree down and it falls and dies. During the next few years which organisms are most likely to breakdown the tree?

Things that limit the growth or population of a system
What are limiting factors?
Organisms that get their energy by eating other organisms
What is a consumer?

What is lack of resources?
