Sun is the ultimate source of energy:
• Sun is the ultimate source of energy for all organisms.
• The green plants cannot prepare their own food in the absence of sunlight. Hence sunlight is essential for them.
• The heterotrophs take their food from plants and if the plants themselves do not have the energy source, they will die which ultimately will affect the heterotrophs.
• Hence, autotrophs or heterotrophs, both require sunlight as the source of their energy(food).
