Because plants are the primary producers, meaning that they are the only ones that can trap atmospheric CO2 and convert it into usable form of energy i.e. monosaccharides, glucose for example. Also, they are very important to reduce the atmospheric CO2 level, which is toxic to animals. They also release O2 i.e. oxygen, necessary for survival of animals, using which, the animals carry out the process of respiration i.e. breakdown of complex food material into simpler one in the presence of oxygen. In this way, plants are important for survival of animals.
