Question

all food chain begins with green plants. why?

Answer 1

Dear student,

All food chains begin with green plants because plants are the only organisms which can use sunlight as the source of energy to synthesise food. They are the primary producers as they have the maximum amount of energy which is transmitted to higher trophic level in the food chain. Only 10%​ of energy is transfered at each trophic level in the food chain. Therefore, tertiary consumers have least amount of energy.
