Environmental Effects Of Agrochemicals
Ecosystem is a collection of communities of organisms and the environment in which they live. Ecosystems can vary greatly in size. Some examples of ecosystems of small tidal pools, home garden, or some cow stomach.
Large ecosystem may include lakes, farmland, forests or stands. Landscape scale ecosystems cover large areas, and may include a variety of terrestrial and aquatic communities.
Everything in life is the earth and its physical environment can be considered as represent the entire ecosystem, known as the biosphere. Ecologists often invent ecosystem boundaries, depending on the specific needs of their work.
For example, depending on the specific interests of ecologists, an ecosystem can be defined as the shoreline vegetation around the lake, or all of the lake or the lake, as well as all the land around it. Because all of these blocks are composed of organisms and their environment, they can be properly regarded as ecosystems.
All ecosystems have some basic common characteristics. They use the energy that is usually provided by sunlight to create complex chemicals from simple materials. At the level of plants, such as carbon dioxide and water vapor in conjunction with the energy of sunlight to produce complex carbohydrates such as starch. As plants are consumed by other organisms, more complex substances produced in their bodies, and the energy is transferred up the food chain.
