Detailed explanation-1: -Plants use energy from the Sun to create organic matter. Plants are then eaten by primary consumers who are in turn eaten by secondary consumers, and so on.
Detailed explanation-2: -Primary producers use energy from the sun to produce their own food in the form of glucose, and then primary producers are eaten by primary consumers who are in turn eaten by secondary consumers, and so on, so that energy flows from one trophic level, or level of the food chain, to the next.
Detailed explanation-3: -An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Because autotrophs produce their own food, they are sometimes called producers. Plants are the most familiar type of autotroph, but there are many different kinds of autotrophic organisms.
Detailed explanation-4: -The plants use 90% of the energy that they get from the sun to fuel the plants own life processes. Consumers then can be said to get their energy indirectly from the sun but receive only 10% of the energy level of the producers.
