The given blank can be filled with photosynthesis.
The photosynthesis is a process, in which the plants make glucose and oxygen from carbon dioxide and water in presence of the sunlight. The photosynthesis is very essential as all the organisms are not capable of making their own food to meet their energy requirements. The glucose made in this process is utilized by the plants themselves as well as by the organisms, who eat the plant.
Answer: Photosynthesis
Explanation:-
Photosynthesis is a phenomenon in which green plants containing chlorophyll use sunlight as a source of energy to convert carbon dioxide and water to form glucose (sugar) and oxygen.
Photosynthesis is the process used by plants, algae and certain bacteria to convert energy from sunlight and turn it into chemical energy in the form of glucose which is used a s a source of energy by many organisms.
The chemical equation for photosynthesis is represented as:
