Rain forests are huge carbon sinks, as plants and trees actively remove carbon dioxide from the atmosphere and store the carbon in biomass. This is a vital ecosystem service for counteracting climate change. Forests regulate the climate, as evapotranspiration from forests influence precipitation patterns and the temperature. Many as yet underdiscovered plants may be of benefit to us as sources of useful products or drugs. Rain forests act as a refuge for vulnerable plant species, thereby protecting them from human over-exploitation and saving biodiversity for future human generations.
Food molecules contain chemical energy which is released when its chemical bonds are broken.
Food undergoes digestion in the digestive system and is broken down into its monomer units. Carbohydrates, which are the principal source of energy, are broken down into glucose. Glucose is the monomer unit of carbohydrates.
Glucose then is taken up by cells and is used in cellular respiration, which involves three main stages namely glycolysis, Krebs cycle and the electron transport chain, through which a glucose molecule is processed to form at least 36 molecules of ATP.
ATP is the form of energy that cells use.

Answer:
The answer is option B) Optic
Explanation:
The optic nerve comprises the postganglionic sympathetic nerves and it assists in conveying of visual from the retina to the brain. The optic nerve projects to the hypothalamus and shows the level of light stimuli in the retina.
