How does light affect 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.

How is light important to plants and animals?

Can there be life without the sun?

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.

Here is another example: Animals at the ocean floors depend on organic matter (dead plants and organisms) that sink to the floor from the surface.

Why do animals still depend on the Sun for energy?

Animals do not make their own food from energy in sunlight. EXPLAIN why they still depend on the sun for energy. Just because animals get energy from the sun indirectly, doesn’t mean they don’t get it at all. Plants get sun energy from the sun directly by making food out of that energy.

Why do all living things need sunlight?

Living things need sunlight. The sun is the source of all energy, heat, and light . The amount of sunlight in an area determines what living thing can survive there. For example, the upper part of the sea or ocean receives a lot of sunlight. It is, therefore, warmer than the ocean floor, which has little or no light at all.
