Answer:
The digestive system ingests and digests food, absorbs released nutrients, and excretes food components that are indigestible. The six activities involved in this process are ingestion, motility, mechanical digestion, chemical digestion, absorption, and defecation.

Answer:
As well as the vivid beauty that comes with great diversity in plants and animals, rainforests also play a practical role in keeping our planet healthy. By absorbing carbon dioxide and releasing the oxygen that we depend on for our survival. The absorption of this CO2 also helps to stabilize the Earth's climate
Answer:
d. neither the light reactions nor the Calvin cycle
Explanation:
Calvin cycle is the name given to a set of chemical reactions that occur in the chloroplast stroma. The chemical reactions that make up the Calvin cycle occur in the carbon fixation step, one of the photosynthesis phases. In this cycle, CO2 is reduced to glyceraldehyde 3-phosphate and ribulose 1.5 bisphosphate, CO2-acceptor, is regenerated.
Photosynthesis is initiated by light reactions, which use light energy to store and transport energy-supplying molecules such as ATP and NADPH.
Neither the Calvin Cycle nor light reactions requires glucose, these processes are initiated by other molecules and are intended to provide products for photosynthesis to occur.
