Inter-species interactions: competition: interaction hurts the growth rate of both species. Answer: exploitation: interaction is good for one species but bad for the other.

Competition: competition occurs when two species both depend on the same re- source, or resources, each species ability to reproduce successfully is reduced by the presence of the other. Answer: survival, growth, producing o spring: species may be very similar, or very di erent. Answer: oaks and maples competing for light. Answer: ants and deer competing for leaves.
