GEOLOGY

Detailed explanation-1: -It radiates light and heat, or solar energy, which makes it possible for life to exist on Earth. Plants need sunlight to grow. Animals, including humans, need plants for food and the oxygen they produce.

Detailed explanation-2: -3.1 The Sun is the major source of energy for organisms and the ecosystems of which they are a part. 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-3: -Most organisms either directly or indirectly use energy from the sun to survive, but not all of them. Plants and some microbes use the energy from the sun to perform photosynthesis.

Detailed explanation-4: -Almost all life on Earth relies on solar energy for food, either directly or indirectly. Producers rely directly on solar energy. They absorb sunlight and convert it into nutrients through a process called photosynthesis. Producers, also called autotrophs, include plants, algae, bacteria, and fungi.

Detailed explanation-5: -Yes, the sun is the primary source of energy on Earth. However, our bodies get the energy from the sun indirectly. We usually obtain energy from the foods that we consume, such as plants and animals. In turn, these plants get the energy from the sun, while the animals get their energy from the plants.
