There were no animals or plants at the start of the earth. Cyanobacteria maybe
Carbon exists as carbon dioxide in the atmosphere which is absorbed by plants during photosynthesis. All food chains start with plants so herbivores get carbon by eating plants and carnivores get carbon by eating herbivores.
animals dat eat both plants and animals are called omnivor and some examples are rabbits ( my fave animal ) hores, dogs ( some type ) pigs, chickens, cat, ravens,and skunks.................... hope dat all helped :-)
People measure the population size of animals and living creatures/plants because if they over populate or start becoming extinct they know what to do if they need to kill or reproduce animals.
Plants are important because the start the food chains and food webs. Plants also give oxygen to oxygen breathing organisms and clean up the air of deadly gases such as carbon dioxide. Animals are important because they keep the food webs and chains in line and they each have their own helpful niche (Niche- the full range of physical and biological conditions in which an organism lives and the way in which the organism uses those conditions). I hope this helped you a lot if you need anymore answers just ask!!

Sexual orientation started when the first animals walked the Earth.
The first plants appeared on earth over 400 million years ago. One of the earliest plants was cooksonia, which did not have leaves or flowers !

Actually, this would be bacteria, because it is how all organisms start out and eventually, they will evolve into the animals and plants we know today. However, humans did not come about until around after the Ice Age, along with the first mammals.
Let's start off with, if there was no sun there would'nt be a earth. The earth is what give the vitamin D and nutrients to plants and help them grow. Most of the planet, (Earth) are plants. Which is a major food source for humans and animals. And animals are a food source to humans and many other species of animals. Keep in mind humans nor animals can not live with out food. The sun also heats up the earth. Without the sun we would all freeze to death. Don't let that stop you there, the reasons for "the suns importance on earth" could go on for ever!
CO2 (carbon dioxide) is exhaled by animals and needed by plants for photosynthesis.
i think its because god made it..............
study of plants, study of animals
we good start picking up trash that is lying around if you go out side to play there is trash. There are ways for all of us that could help and we could help the earth by planting plants outside of your house for the animals.
In the dry season, there is a likely chance that there will be little to no rainfall. Therefore, without water animals and plants start to die.
