What would happen to the nitrogen cycle if there were no green plants?
If there were no green plants there would be no nitrogen cycle.If there were no green plants, the nitrogen that most organisms need wouldn't be transferred to all living things. Nitrogen is in green plants first, and then the herbivores, omnivores, and carnivores get it by eating the plants or eating the animals that eat those plants. Without green plants, those animals wouldn't really have anything to get the nitrogen from. Nitrogen is crucial to all plants in making amino acids and proteins which they need to survive, so there would be no life on Earth.
What were the first animals and plants limited to?
in botany or biology
When did the first marine plants appear on earth?
the first plants appeared about 3000 years ago. the first plant was algae.
What arose first archaebacteria animals fungi plants protists?
Archaebacteria
Do plants photosynthesize or cellular respirate?
This is kind of a guess, but I would say photosynthesis since some of the first organisms on earth were bacteria that did photosynthesis.
What is the first animals and plants at the start of the earth?
There were no animals or plants at the start of the earth. Cyanobacteria maybe
What would happen to the animals on earth if there was no soil?
First of all if plants were gone then eventually there would be no air because plants breath in carbon dioxide and breath out oxygen whereas humans and animals breath in oxygen and breath out carbon dioxide (Therefore plants can't survive without animals and animals can't survive without plants). Also without plants then herbivores would starve and die out and the carnivores would eat each other and then die out and finally humans would die because all the animals and plants died. But the lack of air and starvation would happen at the same time. (But the lack of air would come first.)
Which was the first animal on the earth to have food?
The animal that first evolved, I guess. But no one knows what that was (because it lived millions and billions of years ago) or if there was an animal that evolved before all other animals. It would have eaten plants though because plants are plants, not animals and they use photosynthesis to survive.
What would happen if there was no animals?
There would be no earth because animals and cavemen were here first and then god created people
Who were the first animals to invade the earth were probably?
The Earth has not been invaded. Any invasion of Earth would have to be from beyond Earth, and would therefore be from space.
Why is the sun important for food and plants?
Well, different plants need different amounts of sunlight. They need sunlight for photosynthesis, that's how they make their own food. Without sunlight, there would be no photosynthesis, and plants would not survive.

What will happen to the earth if the sun stop shining?
After long and intricate calculations, our crack team of specialists has concluded that in such an event, the earth would become a much cooler and darker place. As an incidental result, the moon would also become perpetually invisible. Unfortunately, plants would also stop growing. And without plants to eat, animals would become first scarce and then extinct. And without either plants or animals to eat, human beings would rapidly become a lot less interested in reproduction, and the human race would also become first scarce and then extinct.
