AP BIOLOGY

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: -The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs.

Detailed explanation-3: -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.

Detailed explanation-4: -One of the most important sources of energy is the sun. The energy of the sun is the original source of most of the energy found on earth. We get solar heat energy from the sun, and sunlight can also be used to produce electricity from solar (photovoltaic) cells.

Detailed explanation-5: -Sun is the powerhouse of energies. It provides us with heat energy, light energy and solar energy.
