Plants are a source of oxygen, which they release during photosynthesis. All living beings breathe oxygen. Plants are the main food for herbivorous animals, which, in turn, feed on predators. Plants are a refuge for many animals. In their thickets, animals hide from enemies, build dwellings, for example, nests. In turn, animals also play an important role in plant life. Insects pollinate plants. Many animals distribute their fruits and seeds and thus facilitate the dispersal of plants. Crossbills, for example, feed on pine and spruce seeds, blackbirds feed on rowan fruits. Passing through the intestines of birds, rowan seeds remain unharmed and even acquire better germination. When they breathe, animals release carbon dioxide into the environment, which plants use during photosynthesis.
