Green plants get energy directly from the sun's rays through the process of photosynthesis. Most plants use chlorophyll, a magnesium-containing organic molecule, to capture the energy of the sunlight. The light absorbed by the chlorophyll is mostly from the red and the blue regions of the visible spectrum. What is reflected is green light, from the central region of the spectrum, which is why green plants look green. Photosynthesis absorbs sunlight energy. Is photosynthesis an endothermic or exothermic reaction?
Cows are vegetarians. They eat (or should eat) only plants. The carbohydrates that plants make by photosynthesis are used as a source of energy, not only by plants themselves but also by animals. Both plants and animals store simple carbohydrates by making them into larger carbohydrate polymers such as starch and glycogen. Because the cow cannot make carbohydrates directly from the sun's energy as plants do, it eats the plants to obtain the carbohydrates the plants have made. Once an animal eats a plant, it breaks the plant's larger carbohydrates down into simpler carbohydrates such as glucose. Glucose, which is soluble (can be dissolved) in blood, can be carried to the rest of the body for energy use.

Turning milk into cheese involves a change in a substance from one common state of matter to another, in this case, from liquid to solid. Cheese is a concentrated form of milk. Milk is composed of proteins, fats, sugars and water. The process of making cheese is somehow removing that water so that you’re left with the concentrated mass of the proteins and fats. Milk is an emulsion, meaning a huge number of protein molecules and droplets of fat are suspended in the liquid. They must be separated from the water they are suspended in.
