DENDROLOGY

Detailed explanation-1: -All organisms are directly or indirectly dependent on plants for their food. Thus, the sun is the ultimate source of energy for all living organisms.

Detailed explanation-2: -The energy that is harnessed from photosynthesis enters the ecosystems of our planet continuously and is transferred from one organism to another. Therefore, directly or indirectly, the process of photosynthesis provides most of the energy required by living things on earth.

Detailed explanation-3: -Producers such as plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water. This establishes the beginning of energy flow through almost all food webs.

Detailed explanation-4: -Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

Detailed explanation-5: -That’s because almost all living things rely on the steady light and heat of the Sun. The Sun’s heat makes liquid water on our planet possible. And all life that we know of-from bacteria to elephants-needs liquid water to survive. Changes in the Sun’s brightness can change global temperatures.
