Explain why the biosphere is the global ecosystem. Simple answer

Since the school course are all familiar with concepts such as biosphere and ecosystem. By themselves, concepts are different, but they are very interrelated. How? Our task is to explain why the biosphere is the global ecosystem. First let's remember what is ecosystem.

The concept of the ecosystem. The types of ecosystem

An Ecosystem is a system composed of a biocoenosis and a biotope. In other words, all living organisms with their habitat. It is already possible to explain why the biosphere is the global ecosystem. All living organisms within the ecosystem are closely linked by the fact that between them flows a continuous exchange of substances. There are two large groups: natural ecosystems and agroecosystems. The latter are characterized by the fact that was created by man. And she and the other group have a similar structure. Any system includes three units, namely: producers, consumers, decomposers.

First, create organic matter (green plants), the second consume organic matter. Among them are herbivores, carnivores and omnivores. To the omnivorous group is commonly attributed to humans. The decomposers also decided to include various bacteria and fungi. Decomposing substance they carry their dead from the remnants again in the inanimate environment. The ecosystem is only a small part of all life on earth. You should detail to explain why the biosphere is the global ecosystem.

Biosphere - the system of all life on Earth

What do we know about the biosphere? It is associated with the concepts "life" and "ball." In other words, biosphere – the shell of the globe, densely populated by different organisms, and in some degree modified them. The shell of the Earth was formed more than 3.5 billion years ago. At that time only began to appear the first organisms. To the biosphere include the hydrosphere (water shell), part of the lithosphere (the outer sphere) and the atmosphere (envelope of air). In other words, all this can be called the ecological world (ecosphere), that is, a system that includes living organisms, interrelated, and their habitat. In total, the biosphere lives of 3 million different organisms. People also, of course, is part of the biosphere.

So, the biosphere is primarily a system.

Any system is always made up of separate components. Different ecosystems have a relationship not only within themselves, but also closely linked with other ecosystems. Between them, as within even the smallest system, energy exchange occurs, as well as metabolism. United ecosystems form their cycle, which unite in a single global ecosystem. This global system called the biosphere. As it happens in reality?

Why the biosphere is the global ecosystem

This can be Explained by the following example. If we take any of the corners of our planet, we will find in it the sources of life. The oceans, the upper region of the atmosphere, the zone of eternal snow – everywhere there is water. Therefore, in any corner of the planet, we find life.

It was said by Charles Darwin. And, of course, was right. Inhabiting various places on the planet, these organisms form the ecosystem. Being in it, they are all interrelated, primarily with metabolism and energy. Some ecosystem nutrient cycle and energy is interconnected with other systems. Those in turn, too. So happens that many small ecosystems create one big ecosystem called the biosphere.

Biosphere - ecosystem also

If you explain briefly why the biosphere is the global ecosystem, the earthly shell – it is a living area that includes a huge number of life forms. Thus, composed of individual ecosystems, and thus is a global system, the violation of which threatens life on the planet.
