Photosynthesis makes chemical energy available to animals and other organisms Sunlight ⇒ ultimate source of energy for all living organisms → During photosynthesis → chlorophyll absorbs light energy and transfers it to chemical stores of energy in carbohydrate molecules. Fats, proteins other organic compounds ⇒ formed from carbohydrates ⇒ all these substances eventually become food for other organisms All organisms → thus obtain chemical energy directly/indirectly → from plants, because plants are producers of food chains.
Photosynthesis Removes And provides Oxygen → photosynthesis removes from air - and at the same time - produces oxygen Oxygen ⇒ released is used by living organisms ⇒ in respiration ⇒ to release energy for cell activities. Process of photosynthesis → maintains constant level of and in atmosphere
Energy Stored in Fossil Fuels comes from Photosynthesis All energy in fossil fuels (coal, oil, gas) ⇒ comes from the sun, captured through photosynthesis ⇒ burning of fossil fuels → releases energy → which we use in our daily life → such as cooking, generating electricity in our homes
