The sun is the primary source of energy for ecosystems. the sun . when an organism obtains nutrients by feeding on other organisms in the ecosystem, energy is used and released. energy changes form, but it isn’t destroyed as it transforms. this scientific law is called the law .

This scientific law is called as Law of conservation of energy.

Sun is the primary source of energy .Energy once produced by the sun is then utilized by the organisms at various tropic levels. The energy is transferred from one organism to another. Energy is neither created nor destroyed. This is called as law of conservation of energy. Plants uses sunlight and make food   and the energy is then transferred to organisms eating it. When the organism dies the energy is released into the environment. This cycle continues and the the law of conservation of energy is maintained.
