NEET BIOLOGY

Detailed explanation-1: -The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of photosynthesis in plants. A small proportion of this chemical energy is transformed directly into heat when compounds are broken down during respiration in plants.

Detailed explanation-2: -The energy enters in an ecosystem through producers. Plants are producers which convert solar energy into chemical energy through photosynthesis. From producers, the energy is then transferred to the herbivores and carnivores.

Detailed explanation-3: -Energy enters all ecosystems as sunlight? True or False? False! Energy enters most ecosystems as sunlight, but the rest enters the ecosystem through producers!
