Learning Target I will predict if population size will increase or decrease based upon

Learning Target I will predict if population size will increase or decrease based upon limiting factors and carrying capacity.

Carrying Capacity Key Point #1: An environment can only support as many organisms as

Carrying Capacity Key Point #1: An environment can only support as many organisms as there is available food, water, and free space Carrying capacity = maximum number of organisms that can live somewhere, based on the food, water, and free space. Every species has a different carrying capacity. Food, water, and free space are the LIMITING FACTORS that determine carrying capacity

Carrying Capacity Carrying capacity can also have a broader meaning. It can be defined as the number of living things (plants and animals) any area of land or water can support at any one time. Different organisms will have different carrying capacities in the same area. Thus, the carrying capacity of an ecosystem affects everything that lives in it.

Closing An environment can only support as many organisms as there is available food, water, and free space Carrying capacity = maximum number of organisms that can live somewhere based on these limiting factors We can read a carrying capacity graph to predict changes in population size Below carrying capacity = increase Above carrying capacity = decease Over time, population stabilizes at carrying
