1. discuss and give examples of the following community interactions: predation, commensalism, symbiosis, parasitism, mutualism 2. compare/contrast the characteristics of biomes. 3. compare/contrast primary and secondary succession and be able to give examples of each

1. a) predation is when one organism is harmed and the other is benefited. An example of this is when a predator eats/hunts its prey - like a lion eating a lamb

b) commensalism  is when one organism benefits from the other and the second organism is not affected. An example of this are the barnicles on a whale

c) symbiosis is the long-term interaction between two different biological organisms

d) parasitism is when one organism is harmed while the other is benefited

Iwould say overuse ( but not 100% sure ) in the u.s. we tend to overuse water by leaving it running, throwing it away, taking long showers, etc.
