Answer:
Radiant energy to chemical energy.
Explanation:
Photosynthesis is known for the radiant energy transformation into chemical energy. It is a process where plants to take in sunlight, water, & CO2 and convert them into oxygen, and glucose, in this process CO2 is removed from the air.
In the process of photosynthesis, the energy that is captured by the sun is stored in the form of carbohydrates. The photosynthesis process occurs in the chloroplast which is present in the plants, and the pigment is known as chlorophyll which helps to make plant green.
Liches, mosses, grasses and annual flowers, bushes and shrubs, trees. Primary succesion is a type of succesion occuring in an environment. This is a gradual growth of ecosystem from an area without vegatation. This can happen from simple to a more complex organism. The pioneer plants are usually the hard organism that can strive at aharsh condition and gradually shifting to a more adapted to less harsh conditions.
