because they are the only creature that does not need to be fed.they feed others and make there own.they are the first in the food cycle (like rabbits eat carrots,wolfs eat rabbits,....).the carrot is the first which is the plant.
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.
so that the animals will live
Unicellular plants and animals were first forms of life on Earth
Bacteria live in and on animals, humans and plants.
No food for plants=No plants=No food for animals=..................Do I have to say it?........
You can kill part of the earth, including humans. Because humans eat some types of animals, and if we don't have the animals to eat, all humans can die. The animals will die too, they are just like humans.
It was necessary for the universe to cool down before plants could form because plant life requires stable temperatures within a certain range for survival. If the universe remained hot, it would have been too hostile for the emergence and sustenance of plant life. Cooling down created an environment suitable for the development and evolution of plants.
So they can survive
Figure it out yourself
to keep the plants green. we woud not be here on earth without it because we need it to survive, and the animals too. ;)
There were no animals or plants at the start of the earth. Cyanobacteria maybe
Biosphere= the part of the earth where plants and animals live.
You would fins plants and animals in the troposphere, where we live on earth
Water is the necessary device for the survival of life in this earth
The only planet that we know of with plants and animals is Earth.
because the gravity of the earth is forcing you to love me than your parents.
Earth. Animals and plants live all over the earth. You can look for larger concentrations in jungles.
Carbon is a chemical substance found in the Earth but not formed by plants or animals.
