What are Niche and Habitat? Habitat-place where an organism lives. Niche-role and position a species has in its environment. Organisms with the same niche compete if they are in the same habitat.

How do Stability & Disturbance work together? Disturbance-events that change a community by removing organisms or changing resource availability. Stability is the ability of a community to resist disturbance and not change.

What is Biodiversity? The variety of life in an area. Measured by species richness-the number of different species in an ecosystem. Extinction is when the last individual of a species disappears. Endangered species=species that are likely to become extinct. Threatened species=species that are close to becoming endangered. Biodiversity increases the stability of a community
