We live in the cenozoic era, and scientists know more about this era and the epochs it's divided into than any other time period. why is this? a. we know more about the cenozoic era because this is the only era that has had a wide diversity of species living on earth. b. we know more about the cenozoic era because the planet's poles reversed magnetic fields at the beginning of this era. c. we know more about the cenozoic era because fossils don't exist to document previous eras. d. we know more about the cenozoic era because this is the most recent time period in the history of the earth, and we have more information available to study.

D. We know more about the Cenozoic era because this the most recent time period in the history of the Earth, and we have more information available to study.

Explanation:

The Cenozoic era is the era that is by far the best studied and known by the scientists. The main reason for this is that this era is the most recent one, and it is actually the era we live in. Because it is the most recent era, the Cenozoic is abundant with lot of evidence of what has happened in it. The fossil records are very rich as the fossils didn't had that much time to totally decompose. The rock layers are much younger, so they contain much more detailed evidence of the plant life, climate, changes in the environment. The oceanic crust is also in abundance, which is not the case with the other eras as the oceanic crust is constantly suducted.

mark brainliest!

answer: after carbon dioxide enters the leaf through stomata it moves into the mesophyll cells where photosynthesis occurs and glucose is constructed. respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy.
