A population is

• a group of similar species in different areas

• a group of the same species in the same geographic area.

• a group of several species in the same geographic area

Individuals gather in patches, influenced by resource availability and behavior.

• clumped dispersion

• random dispersion

• uniform dispersion

• isolated dispersion
