Answer:
Plants go through a process called photosynthesis that allows them to take carbon dioxide out of the air and turn it into oxygen and energy. The oxygen will later be breathed in by an animal and go through cellular respiration where it will become CO2 again.
Taste bud receptors if not stimulated are normally polarized. With the presence of the food, chemicals from the food bind with the cell protein which depolarized the cell membrane receptor. Depolarization will lead into the propagation of electric impulse. This will lead into the creation of sensory impulse. The larger number of the chemicals in the food will lead into a stronger impulse.
Answer: True
Explanation: It is not a single organism, there is a photosynthetic and symbiotic relationship between the algae and the fungus.
