Multiple Choice

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

• clumped dispersion.

• uniform dispersion.

• random dispersion

• scatter dispersion

Multiple Choice

What are the three types of distribution patterns?

• uniform, clumped, random

• uneven, clumped, random

• uniform, uneven, random

• uniform, clumped, uneven

Multiple Choice

This is the most commonly seen distribution pattern. Example: wolves. This is usually because there are resources found in particular areas and the organisms need more space to survive.

• Random

• Uniform

• Clumped

• Uevenn

Multiple Choice

What is this type of dispersion

• uniform

• clumped

• random

• none of these
