and its own kind. It's a study of all external condition and factors, both biotic ( living ) and

a-biotic ( nonliving ), that affect an organism. To carry out this study, scientists observe

different ecosystems: forests, deserts, grasslands, oceans, or any kind of interaction

between organisms and their surroundings, or with each other, which are called ecosystem

There are four components within an ecosystem. The a-biotic component, which

determines the types of organisms found there, the producers, the consumers, and the

decomposers. These components cause continual change within the system; the exchange

of materials between the living and nonliving. All organisms living within an ecosystem are

dependent on other living and nonliving organisms for survival and continued growth.

Two basic kinds of processes must occur in an ecosystem: a cycling of chemical

elements and a flow of energy. The flow of energy is from the external environment

through a series of organisms and back to the external environment. To preserve the

system, we must try to conserve the specie or manage the natural resources so that th

areas of the continental shelf where their roots can find soil and nutrients. Diatoms and

threats to ocean resources. Little is known about what happens to these chemicals when

The ocean has a huge impact in our lives, and it should continue being that way. But

Animals without backbones are called invertebrates. Lobsters and clams are probably
