What conditions are necessary for the life of plants, animals and humans?

For the life of various organisms, specific conditions are required. This is a certain ambient temperature, humidity, the presence of certain chemicals in water, soil and air. The composition of the air is also of great importance. The availability of sunlight is also very important, especially for green plants and protozoa that are capable of photosynthesis. A certain species needs individual living conditions. An organism that is adapted to life in the forest cannot survive in the desert and vice versa.
