Module 4

• The variety of life forms in a particular ecosystem.

  Biodiversity
• The maximum number of organisms that an environment can support.

  Carrying capacity
• A community of organisms that live, feed and interact with the environment.

  Ecosystem
• A constant increase in the number of population.

  Exponential growth
• Factors that control the growth of a population.

  Limiting factors
• A population growth in which the growth rate decreases with increasing number of organisms, until it becomes zero when the population reaches its carrying capacity.

  Logistic growth
• The measurement of population per unit area.

  Population density
• The ability of an ecosystem to be self-regulating, and again become steady after a disturbance.

  Stability
• The total number of organisms belonging to the same species in a particular environment.
