What is an abiotic limiting factor?
100
Growth of a population in which the rate becomes ever more rapid in proportion to the growing total number or size.
What is exponential growth?
100
How an organism might react to an extreme event such as major drought in order to survive another year (think of the finches we talked about).

A virus wipes out over 60% of the mouse population in an ecosystem which makes them much more difficult to hunt. What type of limiting factor is this?

What is a density dependent limiting factor?

300
The number of organisms a region can support without adverse effects on the environment.
What is carrying capacity?
300
The three specific patterns of dispersion we learned in class.
What is clumped, random and uniform?
300
Organisms like zebras run in herds to avoid predators, this is a pattern called:
What is clumped dispersion.
300
The type of population dispersion that most flowers and plants adhere to.
What is random disperson?
300
The movement of organisms into an environment or area.
What is a immigration?
400
The number of organisms per unit of area.
What is population density?
400
Type of growth where the growth rate decreases as the population reaches carrying capacity.
What is logistic growth?
400
An organism like an elephant which produces very few offspring in its lifetime, the gestation period is very long and live in a stable environment.
What is K strategists?
400
The type of population dispersion that penguins adhere to.
What is uniform dispersion?
