NURSING ANM AND GNM

Detailed explanation-1: –For most biological communities, the initial source of energy is sunlight. Living organisms can harvest this energy by photosynthesis: plants, eukaryotic algae including seaweeds that grow on rocky shores, and cyanobacteria. These organisms are often referred to by ecologists as producers.

Detailed explanation-2: -The sun is called the ultimate source of energy because: It is the primary source of energy for the earth. With the help of solar energy, all green plants(producers) produce food by the process of photosynthesis. In turn, animals eat plants and use that same chemical energy for all their activities.

Detailed explanation-3: -Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun’s core and fuse to create a helium atom. This process, known as a PP (proton-proton) chain reaction, emits an enormous amount of energy.
