Ecology is the study of how organisms interact with their environment, both biotic and abiotic. Abiotic refers to factors of the environment that are nonliving such as temperature, moisture, soil, etc. 2. Individuals that live together are a population. The location where organisms live is called their habitat. The limits or boundaries of a population's habitat is the range of the population.
Communities are associations of all the populations of different species that live together.
Community structure also depends on the rates at which member species arrive and disappear. Community structure further depends on the history of physical disturbances to the habitat. A community, together with the abiotic factors is called an ecosystem. The biosphere is the part of the earth where life exists or can be supported. The biosphere is a collection of complex ecosystems.
