Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide in the process of respiration, which is then used in photosynthesis. While water is broken down to form oxygen in photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.  ATP is manufactured as a result of several processes including fermentation, respiration and photosynthesis.

The purpose of studying and dissecting an earthworm is to help us understand other organisms. Earthworms are organisms that are tube-shaped, segmented worms that belong to the phylum Annelida and in the species Lubricous.  Earthworms decompose organic matter, break it into usable nutrients for their local ecosystems and recycle compost.
