In food chains can be stored energy and matter for considerable periods in animal populations, each chain flowing in a fraction of matter and energy of great importance to the biosphere and man.The increase in human population leads to a tendency to change the distribution of matter and energy in ecosystems and conducive to a fraction, which increases constantly, of the total energy stored in food chains is to their livelihood.
The changes that occur in ecosystems due to the phenomena of migration and development are biological, chemical and physical.The activities of man and alter affect ecosystems on Earth, so it is important to understand both the patterns of evolution as the structure and function of ecosystems and storage and flow of energy and matter. It is also important to know the degradation of food chains, which are initiated into the soil with organic matter from dead plants and animals that continues (in water) by bacteria, fungi and other small animals decomposers that release carbon dioxide, water and energy, which can be incorporated into other food chains more complex animals over. Under certain conditions agencies consume the available oxygen and decomposition of matter is incomplete when it formed products such as methane, alcohol, amines, hydrogen sulfide and decomposed organic matter that can cause serious and grave consequences in living systems. It is estimated that in terrestrial and marine ecosystems is fixed by photosynthesis only 1% of solar energy reaching the Earth. This represents an annual production, worldwide, between 150 000 and 200 000 million tons of dry organic matter, and includes both food for humans as energy that supports living systems of the biosphere, especially the main ecosystems such as forests, grasslands, oceans, wetlands, estuaries, lakes, rivers, tundra and deserts.Given the key role played by energy in living things, the balance of the setting and flow of energy through ecosystems to understand the functioning of ecosystems and environmental factors of the crisis. Absorption and emission of solar energy on Earth.
