morrow to study Lesson 14 wolves and deer, is the ecological balance?
to comprehend what the ecological balance, we must first know the creatures in the ecosystem, along to the course they obtain energy tin be divided into producers,shanghai massage, consumers and decomposers: and often engaged in the ecosystem energy flow and stuff prevalence.
in the ecosystem, producers mainly refers to green plants, they use stems and leaves absorb carbon dioxide in air, soil at basis uptake of water and minerals, and a certain temperature in the sun Next, the inorganic substances into starch, protein, fat and vitamins and other alphabetical stuff. through photosynthesis into solar energy into chemical energy, not only for their own growth and evolution needs, and for other organisms and humans cater edible and energy.
consumers refers to animals such as horses, cattle, sheep, foxes, wolves, lions, tigers, etc., they can not directly use solar energy to organic matter into inorganic materials, only to plants and other animals for food. the consumer, notwithstanding not the aboriginal organic matter producers, but in the consumer body, but also the process of organic reproduction. Therefore, consumers in the ecosystem material and energy transition process, is also an major chapter.
decomposition is a decomposition of assorted micro-organisms . they are capable to break down vegetation and animal residues into simpler compounds and elements returned to nature, re-use for the plant. decomposition in the decomposition of plants and animals,shanghai escort, yet also derive the energy of their own needs.
biological metabolism , growth and reproduction necessitate energy. all biological needs are derived from solar energy. producers (mainly plants) to occupy the solar energy into chemical energy and stored in organic matter (such as glucose) molecules. this chemical can form by the food chain of ecosystems in all appearances of order flow. favor energy, like matter is through the producers (plants), consumers (animals),shenzhen escort, decomposers (microbes) in turn formed into the ecosystem, from organic inorganic mm, and finally returned to nature, constitute a material cycle. In nature, anybody of an ecosystem are constantly engaged in the energy flow and nutrient cycling.
the so-called ecological equilibrium,toronto escorts, that namely, a time of time, the producer, consumer and decomposition of those who have retained a balance among the state, that namely,even apt penetrate Shun Kouwen the sentence, the system vigor flow and nutrient cycling in a long time apt remain settled, this state is shrieked the ecological balance.
course, this balance is dynamic, not static. the interior components of the ecosystem alteration or the unreasonable interference of external elements, will be an shock on the ecosystem, causing changes in the system. However, the ecosystem has a self-regulating capacity, when this change is not meaningful, the energy of the system flow and material cycles can still be behind to natural, so the balance is comparative, short-lived, and not total. Once the interference of external factors over this to destruction. For example, deforestation and tending must be combined in mandate to maintain the balance of forest ecological surroundings; the additional hand, would demolish the ecological balance, not only the decline in forest quality, forest animals, the survival of microorganisms in taint types also changes will also affect the feature of forest ecosystems, resulting in bare ground, soil erosion, overflow and other calamity.
an eco-system producers, consumers and decomposers in maintaining the ecological balance of the process, has its special status and character. between the various components are interrelated, mutual restraint, interdependent, and if artificially so that the ecological system of a species evaporate, or the introduction of a species will affect the entire balance of the ecosystem. For example, Australian mainland in the long process of evolution, developed its own ecosystem, the British introduced European rabbits in the 40's, the results propagating disaster, very serious damage to grassland, when the Australians are often terrified almost rabbits.
When the eco-system is in balance, is most profitable to the flow of energy and material wheel. to maintain balance in the longer term, this system ambition be up to the species, biological volume is too the largest. a intricate ecological system is marred , it must be quite a long time to regain. For instance, when the discharge of sewage to the creeks and oceans because a little while, the water can be discharged into the consume microorganisms break down into simpler compounds or chemical elements, to make the water clean and restore. Once discharged into the sewage More than microbial decomposition, water quality ambition deteriorate smelly, fish and shrimp will grow well, serious alternatively even be poisoned. So always people activities must be conducted in agreement with ecological laws can no violate the objective law.
