|
Definition
|
|
Term
|
Definition
| Individuals are equally likely to be anywhere within the area. |
|
|
Term
|
Definition
| High-density clumps are separated by areas of low abundance. |
|
|
Term
|
Definition
| Individuals maximize space between them by being uniformly spaced. |
|
|
Term
|
Definition
| the population is growing at constant rate without ceasing. |

|
Definition
| It varies from the resources within a country. The more people we have the ore even the distribution of resources we will have. |

Term
|
Definition
| Larger amount of children (0-19) than the ages of childbearing. |
|
|
Term
|
Definition
| The amount of children is relative the same of the age group of childbearing. |
|
|
Term
|
Definition
| The amount of children is smaller than the amount of people within childbearing ages. |
|
|
Term
| Explain why an increase in prey population is followed by an increase in predator populations a few years later. |
|
Definition
| If there is high population within the the prey, they will start to decline because of lack resources. Then the the predator will grow because they hunt the prey which causes a decline in the prey, which increases the population of the predators. |
|
|
Term
| Explain how changes in carnivore population can affect the growth of nearby vegetation. |
|
Definition
| The carnivore hunt the herbivore which increases the growth of vegetation. When the carnivore population declines from lack of prey, the prey feeds on the vegetation. So the vegetation declines. |
|
|
Term
| Explain how changes in carnivore population can affect the growth of nearby vegetation. |
|
Definition
Urine- Tell the nutritional status of species
Scat- The food they eat and genetic profile
Bones- Tell how the animal die by being hunted or natural cause, such as disease. |
|
|
Term
| Explain why warming climate tends to decrease moose populations |
|
Definition
| Moose needs shade nor like to sweat. Moose rest so they aren't eat as often. Without eating they don't have enough fat to stay warm in the winter. |
|
|
Term
| Describe two methods by which ecologists determine population size. |
|
Definition
| Surveying an area by counting all the population or estimating a section and then multiplying. |
