Other animals eat animals that eat the plants. An organism's patterns of behavior are related to the nature of that organism's environment, including the kinds and numbers of other organisms present, the availability of food and resources, and the physical characteristics of the environment. When the environment changes, some plants and animals survive and reproduce, and others die or move to new locations. All organisms cause changes in the environment where they live. Some of these changes are detrimental to themselves or other organisms, whereas others are beneficial.
Humans depend on both their natural and their constructed environment.
The habitat is the environment in which particular organisms live. Resources include those things that we get from the living and nonliving environment to meet the needs and wants of a population. The supply of many resources is limited. If used, those materials can be extended through recycling and decreased use. Environments include the space, conditions, and factors that affect individual's and population's ability to survive and quality of life.
