Row 1, Col 1

This describes how individuals in a population

are distributed. Clumped(humans),

uniform(trees in an orchard), or

random(trees in a forest).

What is dispersion?

An example of type II survivorship curves, which

describe organisms in which thelength of survivorship is at

random, that is, the likelihood of death is the same at any age.

A factor, which has made exponential growth possible,

includes advances in medicine, such as the discoveries of

antibiotics,vaccines, and proper hygiene.

What is reduction in disease?

By pursuing slightly different resources or securing their

resources in slightly differentways, individuals minimize

and maximize success.

What is resource partitioning?

A conspicuous pattern or coloration of animals that warnspredators that they sting, bite,

taste bad, or are otherwise to be avoided.
