What is :ecosystem?community?popu...

Answer 1

Ecosystems vary in size. They can be as small as a puddle or as large as the Earth itself. Any group of living and nonliving things interacting with each other can be considered as an ecosystem.Within each ecosystem, there are habitats which may also vary in size. A habitat is the place where a population lives. A population is a group of living organisms of the same kind living in the same place at the same time. All of the populations interact and form a community. The community of living things interacts with the non-living world around it to form the ecosystem. The habitat must supply the needs of organisms, such as food, water, temperature, oxygen, and minerals. If the population&#039;s needs are not met, it will move to a better habitat. Two different populations can not occupy the same niche at the same time, however. So the processes of competition, predation, cooperation, and symbiosis occur.

In biological terms, a community is a group of interacting organisms sharing an environment. The word community is derived from the Latin communitas (meaning the same), which is in turn derived from communis, which means &quot;common, public, shared by all or many&quot;[1]. Communis comes from a combination of the Latin prefix com- (which means &quot;together&quot;) and the word munis (which has to do with performing services).

In human communities, intent, belief, resources, preferences, needs, risks and a number of other conditions may be present and common, affecting the identity of the participants and their degree of cohesiveness. Traditionally in sociology, a &quot;community&quot; has been defined as a group of interacting people living in a common location. However, the definition of the word &quot;community&quot; has evolved to mean individuals who share characteristics, regardless of their location or degree of interaction.

In sociology and biology a population is the collection of people or individuals of a particular species. A population shares a particular characteristic of interest most often that of living in a given geographic area. In taxonomy population is a low-level taxonomic rank.

Human populations can be defined by many characteristics such as mortality, migration, family (marriage and divorce), public health, work and the labor force, and family planning. Various aspects of human behavior in populations are also studied in sociology, economics, and geography.

Study of populations is almost always governed by the laws of probability, and the conclusions of the studies may thus not always be applicable to some individuals. This odd factor may be reduced by statistical means, but such a generalization may be too vague to imply anything. Demography is used extensively in marketing, which relates to economic units, such as retailers, to potential customers. For example, a coffee shop that wants to sell to a younger audience looks at the demographics of an area to be able to appeal to this younger audience.
