Where does the energy for photosynthesis come from?

From the sunlight (together with CO2 and water)

Explanation:

Photosynthesis is a process performed by the plants (also some algae and bacteria) in which the energy of sunlight is transformed into chemical energy usable by those plants. Necessary components of this set of reactions are sunlight, water and CO2, while resulting products are glucose and oxygen. Products of photosynthesis are then used in the metabolic processes known as cellular respiration. During the cellular respiration, glucose and oxygen are used for the production of ATP, CO2 and water. Cellular respiration is performed in all living organisms.

Photosynthesis occur in the chloroplast, membrane organelles with photosynthetic pigments (such as chlorophyll).

its been noted for the past decade or so that there is some (approximately 5% to 7%) shrinkage in the brains of people who have schizophrenia, most notably in the gray matter, which is an important part structures in the brain’s amygdala, hippocampus and parahippocampus, which are all involved in memory storage and retrieval memory storage and retrieval.

behavioral response need communication and thus co-ordination at several levels such as interaction among cells, organ system and the entire organism.

behavioral response produces both internal and environmental stimulus.
