What are abiotic factors?
Abiotic factors are elements of a living ecosystem that affect the viability of the system of growth or survival, but which in themselves are not biological in nature. These environmental factors include common conditions such as temperature, air flow, available light and inorganic components of the soil. The wide -based abiotic factors that can affect organisms include an increase in terrain, climate change and the level of precipitation that the region receives during the vegetation periods. For example, a climate with long rough winters, such as the tundra area, will reduce the growth of most plants, except for mosses and heaths, which are resistant in a cold environment where the Earth is frozen for most of the year. Animal species are also limited in such an environment to those that have strong insulating coats and live in low direct light conditions or where food sources are rare, such as polar bears, polar harars or reindeer.
cheMicko factors in the soil, atmosphere and water supply of ecosystems are often determined by abiotic factors that take place on geological timers. They may include elements that affect soil composition such as volcanic activity, and wind and water currents that are directed by lunar tidal cycles. The temperature ranges in the climate are also affected by increasing the soil and also by how the terrain affects precipitation patterns and air pressure systems that flow through it.
The effects of living organisms on the environment are often interconnected with abiotic factors to the extent that if a person changes drastically, the other. Human activities in the environment can also change natural abiotic factors, such as jesters patterns that over time can change the local ecosystem and organisms that can survive there. The best example in history is the process of deforestation.
extensive tropical or mild forests such as once existed in a fertile crescent along the large area of the east coast border withThe Mediterranean Sea, maintained rain patterns that maintained the ecosystem fresh and environmentally diverse for many of the country's earliest civilizations. Intensive deforestation of the fertile area of crescents by various companies from the Sumerians in 2000 BC to reduce the forest cover to 10% of earlier levels, resulting in a weakness of water and soil and a significantly reduced annual collision that changed the climate to a hot, desert area.
A similar formula takes place in the current time with rapid deforestation of the Amazon basin in South America. It is estimated that 20% of the Amazon rainforest has been cut off since 2011 and another 20% will disappear in the next two decades. At this point, scientists in the environment believe that the forest will reach a reversal point where abiotic factors begin to spread their natural ecosystems. This is partly due to the fact that the forest produces half of its own precipitation moisture that releases back into the air, and this drying out of the regionIt will lead to an increase in other abiotic factors such as the spread of fires, drought, and release of greenhouse gases, because forests that contribute to global heating and perientation and periodic influence.
