Communication between the kingdom of animals and the kingdom of plants is obvious. One cannot exist without another, and chains of communications can sometimes be surprisingly difficult and unobvious.
Water, light and air - indispensable conditions for life
Overwhelming part of animals and plants for life and growth needs water, air, food and light. Green plants for survival use photosynthesis, it is the most difficult chemical process. Water is necessary to plants to stabilize their cages, to support stalks and leaves. Animals for obtaining vital energy need to drink water, there are plants, and parts of types – other animals. Actually therefore animals are in the first place in a food chain.
What is eaten by plants and animals?
The majority of plants does not eat living beings, but develop energy independently. Green plants do it by means of green substance in leaves which is called a chlorophyll. Plants need food and water. As a rule, plants receive both by means of a root system. Some plants possess other ways of receiving food or water. Plants which live on trees can form the leaves tanks funnels in which collect water.
Carnivorous plants (which not really there is a lot of) by means of digestive juice digest caught on adhesive or in traps of insects.
Plants on which light does not fall slowly perish. At first they get rid of leaves, so they can transport all forces on a stalk and roots, but, despite this, after a while they die. For this reason in the winter when nights become long, plants always limit growth. Not only plants, but also animals depend on light. Of course, a part of animals learned to adapt to darkness, and some "passed" to a nocturnalism. For example, moles practically went blind over time as underground the acute eyesight is necessary for them not too. But in general, it is necessary animals without sunlight not too well. Light is necessary for production of vitamin D which is important, for example, for growth of bones. In the nature there are producers (producers) which create biological weight, and konsument (consumers) who consume this weight. The plants developing by means of photosynthesis are producers. Konsumentami are herbivores. And herbivores are often eaten by predators.
Example of a short chain: grass-rabbit-fox. Example of long: seaweed – water insects – fish – a seal – a polar bear. And when the "finishing" link perishes, his body serves as food for someone else.
Such interrelation is called a food chain.
