Do you really mean to say "biosphere?" I ask because this is a very broad question since "biosphere" is usually taken to mean all the parts of Earth on which life can exist. So we're talking about everything from deep-sea vents to polar ice caps.
It's also hard to know what you mean by factors that influence life...
What makes life possible is energy. This energy is taken from the sun through various processes and passed through food chains to provide nutrition for every living thing on Earth.
Within different parts of the biosphere we have different kinds of zones called biomes that all have different types of life. Different biomes are caused mainly by differences in climate.
If you could be more specific with your questions, you would get better answers...
The main factors influencing life are
- Abiotic factors,
- Biotic factors.
- Anthropogenic factors
Abiotic factors are all lifeless inorganic and organic elements of Biosphere (temperature, terrain, climate, soil humus, etc.). The major abiotic factors are given below.
Determine adjustment, so the spreading, also limiting of the population, depending on climatic conditions (temperature, humidity, precipitation, winds blow, the intensity of sunlight, etc.).
Living environment for all organisms, is directly dependent on the geographical location of their area of development (latitude, longitude, altitude).
This factor, is a geographical-climatic one, caused by climatic features, depending on terrain, especially altitude, but also on the slope inclination or slope exhibition.
Type of rock from the ground surface and especially from the depth, determines soil properties and therefore plant development on account of which, directly or indirectly, all other living creatures are alive, including humans.
Factor characterizing the soil, in all its physical and chemical properties (pH, structure, texture, volume, etc..),having an overwhelming role for all food chains.
Biotic factors are all organic elements endowed with life of the Biosphere (bacteria, actinomycetes, fungi, plants, insects, vertebrates, etc.) and mutual relationship established between them. The role of biotic factors is essential to all organisms and populations, for in isolation, they can not survive, even if they have the most favorable conditions offered by biotic factors. Thus, through biotic factors occurs insect pollination, which ensure the perpetuation of many plant species. The existence of mushrooms - allow for many forests to exist, the optimum development of herbs leads to maintain herbivore animals, etc.
In environment, is involved a very stressful and complex element, namely the anthropogenic factor, ie those determined by human activity. Human, through its activities affect, very pronounced and often negative, the entire biosphere. However, there were few cases in which, through human intervention (creation of protected areas, reforestation, rational exploitation of natural resources, etc.), Nature had won. Soon or later every man will have the task of repairing what was damaged, otherwise, its very existence is jeopardized.
