Community ecology is the study of interactions between different species of living things, and lets ecologists examine the effects of predator-prey relationships, parasites, and mutually beneficial interactions. In this episode of Crash...

From this video you should know the difference between interspecific and intraspecific, and that interactions can be positive, negative or neutral. Interspecific interactions are between different species (think international)....

Interactions occur in every habitat, some are between members of the same species - and are called intraspecific interactions. Whereas, some are between members of different species and are called interspecific interactions. Just think...
