Flashcards in Overpopulation Deck (25):
0

The process used to determine a population of a group of organisms that are mobile and harder to track

Mark recapture

1

Limiting factors that affect populations that are used by affects created by increased population

Density dependent

2

The dramatic increase in a populations total over a short period of time

Exponential

3

The process used to determine the population of a group of organisms that are easily identified and located

Census

4

Another term for exponential growth

R selective

5

The amount of food energy available on the planet

Net primary productivity

6

Maximum number of organisms that an ecosystem can indefinitely support

Carrying capacity

7

The study of how organisms interact with their environment

Ecology

8

Things such as Illness lack of space competition lack of food and pollution that cause populations to be reduced

Limiting factors

9

The type of dispersion in which organisms are spread evenly through an ecosystem

Uniform

10

The limiting factors that are not caused by population increases

Density independent

11

The total number of one species in an area of an ecosystem

Population

12

The type of dispersion and which groups of organisms are grouped together closely

Clumped

13

The term used to describe the effect that organisms and people have on their ecosystem that is determined by how many resources they use

Ecological footprint

14

The birthrate minus the death rate of a group of organisms

Growth rate

15

The term for the rise in a population even though the growth rate is decreasing

Demographic momentum

16

The name for substances that cannot be re-created after they are used up

Nonrenewable resources

17

The process of birthrates gradually decreasing it to match Loring a death rates

Demographic transition

18

Another term for caring capacity with in a population

K selective

19

The type of dispersion in which there is no definite pattern or growth of organisms in an ecosystem

Random

20

Shows individuals that have a high probability of surviving through early and middle life but a rapid decline into surviving later life

Type one survivorship curve

21

Roughly constant mortality rate for the species through its entire life

Type to survivorship curve

22

Few individuals will live into adulthood and die as they get older

Type III survivorship curve

23

Three limiting factors in an ecosystem

Whether food source space

24

Three reasons why the net primary productivity production of 21 billion is not realistic

Humans are not the only organisms on earth our diet will not consist of vegetables only we cannot live without natural forces
