100
Things such as light, water, nutrients, minerals and oxygen that can affect a populations ability to grow.
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).
What is stop reproduction for a season to save needed resources?
100
Populations of predators and prey experience this cycle.

What is changes in their numbers over periods of time?

100
Name 2 things of the 4 that affect population growth.
What is birth rate, death rate, immigration, emigration?
200
The movement of organisms out of an area or population.
What is a emigration?
200
The pattern of distribution of organisms within a habitat.
What is dispersion?
200
Two factors that might cause carrying capacity in an ecosystem to change.
What is food, water, ecological conditions, space, shelter?
200

Name 2 things that humans can do to consciously change their environment

What is combat disease, make medical advancements, provide clean water, develop methods for producing more food?

200
Things such as weather, natural disasters, pollution, sudden climate change that can affect populations.
What is a density independent 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?
400

The factors such as disease, competition, predators, parasites and food.

What is Density-dependent factors?

500

The study of human population size, density, distribution, movement, and birth and death rates.

What is demography?

500

The number of organisms tends to rise and fall around the carrying capacity due to limiting factors. 

What is fluctuations?

500
Organisms which live in unstable environments, reproduce many young in a short timespan evolved this type of strategy.
What are R strategists?
500

Calculation of population growth rate.

What is Birth rate minus death rate, then divided by 1000 and described as a percentage.

500

Age structure with the pre-reproductive age group with the smallest number of the population.

What is negative growth?
