<em><u>All living things use a process called respiration to get energy to stay alive. Cellular respiration in plants is the process used by plants to convert the glucose made during photosynthesis into energy which fuels the plants’ cellular activities.</u></em>
photosynthesis produces oxygen and glucose faster than respiration consumes it. Photosynthesis also uses carbon dioxide faster than respiration produces it.
Due to the large number of fossils being discovered at that time Darwin proposed that species change over long periods of time.
Explanation:
The theory of Darwin was that the species change in accordance to their environment, thus they develop advantageous traits so that they can be more competitive.
