Predators eat other organisms.

Prey are eaten by predators.

200

200

Omnivore- BOTH plants and meat

Carnivore- ONLY meat

300

300

What are some positive things that can happen if an introduced species enters a new ecosystem?

1. They will no longer have predators or parasites from the old ecosystem

2. The introduced species effectively contributes to the ecosystem

What are all the levels of organization in the environment in order from smallest to largest? Define what belongs in each level.

500

Imagine that a predator population decreased. What would be the effect on the prey population? What about the food web as a whole?

Prey population would increase because no one is hunting them and the food web would become imbalanced and possibly disintegrate as a result.

500

What is commensalism? Give an example.

Commensalism is a symbiotic relationship where one organism benefits and the other is unaffected. Urchin and shrimp or the flower and trees.

500
