Why would we not have animals without plants? try to create an original enough answer! ^^ Thank you!

plants are food for deers and animals that are herbivores if there are no plants no deers if no deers no animals such as wolves  cause they are carnivours

Explanation:

Humans and animals use the oxygen (O2) in the air for their energy process and produce CO2 as waste. A plant does the exact opposite. ... If there were no plants on the planet we wouldn't be able to breathe. Humans in particular, however, also produce other waste

Explanation:

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.
