8th Grade Life Science

Ecology

1. Two types of organisms may interact with one another in several ways: They may be in a producer/consumer, predator/prey, or parasite/host relationship. Or one organism may scavenge or decompose another. Relationships may be competitive or mutually beneficial. Some species have become so adapted to each other that neither could survive without the other. (AKSci - A.9, A.13, A.14a)

Examples of What Students Should Be Able to Do:
