(i) The process of photosynthesis provides the autotrophic organism with the energy and carbon needs.
(ii) It is described as the procedure through which autotrophs absorb elements from their environment and transform them into forms of stored energy.
(iii) This material is consumed in the form of carbon dioxide and water, which when combined with chlorophyll and sunlight yields carbohydrates.
(iv)Carbohydrates\’ primary function in a plant is to fuel it. Instead of being used right away, the carbs are stored as starch, which acts as an internal energy reserve.
(v) The plant can utilise the stored energy as and when it is needed.
