Organisms must take in food, oxygen and water, and other essential substances, from the environment. output Carbon is an essential element for life on Earth. first evolved approximately 2.7 billion years ago, and soon after this oxygen began to exist in the atmosphere. Radiation from the sun is the source of energy for living organisms. Organisms must take in food, oxygen and water, and other essential substances, from the environment. During the day, provided the rate of photosynthesis is sufficiently high, plant leaves and water plants give out oxygen. Glucose is the starting point for making the materials that plants need to live. Revise how plants make their own food using photosynthesis for GCSE Biology, AQA.
