Community

100

These types of interactions between two different individuals within the same species.

Intraspecific

____ is the variety of life on Earth at all its levels, from genes to ecosystems, and can encompass the evolutionary, ecological, and cultural processes that sustain life.

Biodiversity

200

These types of interactions occur between two individuals from different species.

Interspecific

200

A member of one species, predator, eats all or part of the body of a member of another species, prey.

Predation

200

A(n) ____ is an organism that cannot produce its own food, and gets nutrition from consuming other organism.
