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. Without heat from the sun, Earth would freeze.

Detailed explanation-2: -Sunlight plays a very important role in sustaining life in the ocean. It first penetrates the water column, heats it, generates currents, and finally, is absorbed by phytoplankton, which uses this source of energy captured by pigments such as chlorophylls to synthesise organic matter from water and inorganic nutrients.

Detailed explanation-3: -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. The sun heats the earth’s surface and the Earth heats the air above it, causing wind.

Detailed explanation-4: -The correct option is A True. Sun; the ultimate source of energy: Sun is the ultimate source of energy for all the organisms on earth. The energy from the sun is directly utilized by some organisms and other organisms depend on these organisms for their energy requirement.
