How does the sun affect the activities of humans and other animals?
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. Solar energy is essential to agriculture—cultivating land, producing crops, and raising livestock.
In what ways does the sun’s energy affect the earth?
Nothing is more important to us on Earth than the Sun. Without the Sun’s heat and light, the Earth would be a lifeless ball of ice-coated rock. The Sun warms our seas, stirs our atmosphere, generates our weather patterns, and gives energy to the growing green plants that provide the food and oxygen for life on Earth.
How does the suns heat affect 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 does the Sun affects the living things?
Without the Sun’s heat and light, the Earth would be a lifeless ball of ice-coated rock. The Sun warms our seas, stirs our atmosphere, generates our weather patterns, and gives energy to the growing green plants that provide the food and oxygen for life on Earth.
What are the effects of the Sun on living things?
Without the Sun , Earth’s land, water, and air would all be frozen solid! Life on Earth would cease to exist. 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.

How does sunlight affect an ecosystem?
The two most important climatic factors for ecosystems are sunlight and water. Sunlight is necessary for plants to grow, and to provide energy to warm the earth’s atmosphere. Light intensity controls plant growth. At the other maximum, some plants and animals only survive by being submersed in water.
What happens when our sun dies?
But for the sun, death is not the end. While about half its mass will flood out, the rest will crush together at the very center of the planetary nebula. This will turn into a tiny, bright, ultra-dense ember of the sun’s core, no larger than the Earth. This kind of smoldering remnant is called a white dwarf star.
