Number of individuals of a species an ecosystem supports before resource limits reduce survival

Species are typically larger, grow more slowly, less offspring and spend more time parenting

Interaction where both species involved are harmed and pop. growth rates are reduced is termed

Organisms that are small, short-lived, opportunistic, and grow irregular boom &bust pop. cycles

Trophic level responsible for processing organic material&returning nutrients to the ecosystem.

A single kind of organism that occupy a vital ecological niche in a given location is called a

Broad geographic zones whose plants and animals are adapted to different climate patterns

These are the essential, and often limited mineral nutrients required for ecosystem health.

Interaction where one species benefits and the other is not affected is termed

What occurswhen predators in a food chain suppress the abundance of their prey?

Simultaneous evolution of two or more species of organisms that interact in significant ways is

Generally speaking, plant and animal biodiversity is uniformly distributed across the planet.

The most important biogeochemical cycles affecting ecosystem health are the
