Document Summary
Competition can be direct or indirect, vary in its intensity, and occur between similar or dissimilar species. Here only showing 2 resources 2 axes. Bring this idea to the previous slide batwing crab is smaller and needs to hide in corals because there are large competitors that also want to eat the queen conchs.

Resources: components of the environment (e. g. , food, water, light, space) that are required by species. Palm trees sandy soil, fair amount of moisture in the air, can tolerate the salty breeze. They are competing below the surface of the sand for freshwater. Freshwater table is very thin, island gets very little rain. Indirect: exploitation competition: individuals reduce the supply of a resource as they use it. Shark taking away the resources of the crab.
