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.

How is sunlight important to plants and animals?
The energy from the sun is transferred from plants to animals when animals eat the plants. Animals also benefit from the sun's effect on their bodies, because sunlight on skin produces vitamin D, which is important in the formation of strong bones. Animals also get vitamin D by eating plants.
How is sunlight useful to plants?
Plants rely on the energy in sunlight to produce the nutrients they need. But sometimes they absorb more energy than they can use, and that excess can damage critical proteins. To protect themselves, they convert the excess energy into heat and send it back out.
How is sunlight useful to us?
Vitamin D. The sun's UV rays help your body make this nutrient, which is important for your bones, blood cells, and immune system. It also helps you take in and use certain minerals, like calcium and phosphorus.
How is sunlight used by humans?
All day, we use sunlight to see what we're doing and where we're going. Sunlight turns into heat when it hits things. Without the sun, we couldn't live on the Earth—it would be too cold. We use the sun's energy to heat water and dry clothes.
Why is sunlight important for the survival of living organisms?
Why is sunlight important for the survival of living organisms? ... Sunlight allows decomposers to break down dead organisms, which plants and animals use as energy for photosynthesis. Sunlight is needed for plants to produce food, and the energy is then passed to other organisms through food consumption.
Why does sunlight help plants grow?
The sun is the main source of energy for almost every living thing on Earth. It gives a plant the light energy it needs to photosynthesize, which converts that light energy into a storable form (glucose) and keeps plants alive. A by-product of photosynthesis is the oxygen all animals need to survive.
How is light important to animals?
The Major Effects of Light on Animals are as follows: ... The growth, colouration of plumage or body, migration, reproduction and diapause are affected by light in various insects, birds, fishes, reptiles and mammals. Many animals prefer to remain in dark, while others like hydroids fail to survive in absence of light.
Why do humans need sun?
Sunlight is essential for human health and well-being. The health benefits of sunlight include generating the production of vitamin D, supporting bone health, lowering blood pressure, preventing disease, and promoting good mental health.
How does the sun help the Earth?
The sun has extremely important influences on our planet: It drives weather, ocean currents, seasons, and climate, and makes plant life possible through photosynthesis. Without the sun's heat and light, life on Earth would not exist.
How does the sun provide energy for animals?
All nutritional energy comes from the Sun: plants use chlorophyll to photosynthesize the Sun's energy into plant energy, and then animals either feed on plants for that energy or they feed on the animals that have eaten that plant energy. The food chain begins with the Sun and then the energy flows to producers.
Do all animals need sunlight to survive?
Sunlight is vital for all animals, even though different animals need different amounts of sunlight and in different ways. For example, many mammals and reptiles such as snakes, turtles, and lizards come out during the day to bask in the sun to raise their body temperatures and become active.
Can human live without sunlight?
It is unlikely, though, that an adult could die directly and exclusively from prolonged darkness. Most likely a person would become ill and die from a range of chronic diseases caused by lack of sunshine, such as diabetes, high blood pressure, and tuberculosis.
