Why is the sun important to the food chain?

Answer 1

Almost all life on earth gets its energy from sunlight, either directly or indirectly. The earliest forms of life probably did not, and there are still forms of life that might not, but at some point, living things began to use the energy in sunlight to convert available chemical compounds that could be stored and later reused to make other chemicals for growth, reproduction, repair, and so on. These were probably ancestral to cyanophyta, and, in fact, to all green plants.

Some plants, vegetarian animals, fungi, and various bacteria consume either living green plants or those plants when they have died and/or decomposed to some extent. Omnivores are animals that do this and also eat other animals to some extent. Carnivores eat other animals. But animals that eat other animals are getting their energy indirectly from chemical compounds that depended in one way or another on plants converting sunlight.

When all these things die, they are eaten or decompose and the chemicals in them go through the cycle again.

But the sunlight is the original source energy for most living things.

There are living things that consume such things as hydrogen sulfide from deep sea thermal vents. Even so, it is hard to imagine that any of these things would be completely free of chemical compounds influence by sunlight at one time or another.

Answer 2

The sun is the main source of energy so the sun give off energy to the producer(plant) then it go's to the herbivore then 10% of the energy is distributed to the omnivore and herbivore, so sun effects a food web because it is the source of all the energy hope this helps :)

Answer 3

the sun is very important in a food chain, for example lets do a food chain with the sun, grass, a cricket, an anole, and an owl. first you have the sun which supplies the energy required to produce grass, then the cricket eats the grass, then the anole eats the cricket, and then the owl will eat the anole, so as you can see, the sun is the most important thing in a food chain, because with out the sun you cant have grass or another producer so then you cant have any animals to eat the producer so you wouldn't have a secondary consumer so then you wouldn't have a food chain. So, the sun provides the energy required to fuel all of the form of life we are familiar with.

Answer 4

The role cf the sun in food chain is to LIGHT and HEAT;

Answer 5

It gives light that gives producers energy that consumers eat.

Answer 6

Sun is the main form of energy the plants produces food from sunlight.

Answer 7

Because it provides life to all living things, and perhaps the "non-living" too.

Answer 8

It helps grow the plants which feeds animals which we feed on.

Answer 9

What role does the sun play in the food chain
