A community is a level in organization that is....

• made of populations of different species that live in the same place and interact.

• a single individual species of organisms that are similar.

• all the individual organisms of the same species in the same place.

In determining population of a species you would have to use this type of observation and count all of the species in the ecosystem.

• mark and recapture

• indirect observation

• direct observation

• sampling

In determining population this type of observation would have you counting nests or signs of an organism.

• indirect

• direct

The largest population an area can support is called its...

• carrying capacity

• limited factor

• adaptation

• biotic factor

To measure population density, you must divide the number of individuals living in a defined space by the

• area of the space
• birth and death rates
• carrying capacity
• height of the space

Nesting birds often space themselves evenly from other nests. This pattern is called

• clumped dispersion.
• uniform dispersion.
• random dispersion
• scatter dispersion
