  2. Vocabulary for chapter 4

  3. 1. Carrying Capacity- The number of organisms of one species that an environment can support. Example: When the flood occurred last spring many animals could not find food and they died

  4. 2. Demongraphy- the study of human population growth characteristics. Much of the demographics gather on people come form the Census report taken by the government

  5. 3. Immigration- the movement of individuals into a population.

  6. 4.Emigration- the movement of individuals out of a population.

  8. 5. Biodiversity- refers to the variety of life in an area.

  9. 6. Extinction- the disappearance of a species when the last of its members dies. 7. Endangered species- when the number in a species becomes so low that it is in danger of extinction. 8. Acid precipitation- acid rain that can cause the death of trees and wildlife

  10. 9. Exotic species- are organisms that are not native to a particular region. 10. Captivity- organisms that are held by people. 11. Reintroduction programs- release organisms into areas where they once lived.

  11. 12. Conservation biology- the study of methods to preserve the Earth’s biodiversity 13. Legal protection of species- provides laws to make it illegal to hunt animals.

  12. 14. Habitat corridors are natural strips that allow migration of organisms Example: Areas that have protected life are connected to other areas with protected life. This linking allows migration.
