Because what they eat requires sunlight to live, therefore without sunlight they'd have no food.
The plants use the sunlight, the mice eat the plants, the hawks eat the mice. 'Tis the circle of life.
Photosynthesis
Because it is sunlight that powers photosynthesis (producing all the food we eat) and fossil sunlight that is the energy contained in fossil fuels.
People get their energy from sunlight indirectly by either eating plants or eating animals which ate plants. Plants get their energy from the sun.
Heating of air by sunlight is the source of wind.
Animals only depend on plants if they are herbavores and if they do depend on plants they eat them to get the energy the plants make from sunlight using photosyntheses.

Yes - indirectly. We get energy from the food we eat, which comes from animals or plants; animals also get their energy from plants; and plants get the energy from sunlight.
The plants use the sunlight, the mice eat the plants, the hawks eat the mice. 'Tis the circle of life.
Animals depend on food for energy, energy gives them the ability to move, grow, and reproduce.
By eating plants.
animals get energy from the food they eat that gives them energy
Photosynthesis
By the food chain all animals get their energy from eating other animals which eat plants, plants make energy using sunlight therefore the dead animals all got their energy from sunlight, the dead animals became crude oil therefore, crude oil gets its energy from the sun QED
Look at it this way:-All life needs energy, to grow, move, reproduce etc.The source of this energy is the light from our local star (the Sun).Animals can not make thir own food or use of sunlight directly - they obtain the energy they need by eating plants or other animals that eat plants. Animals are consumers.Plants however can make direct use of sunlight, their green leaves trap the sunlight and store the energy of the sunlight as chemical energy in sugars which they produce. Plants are therefore called producers.Thus as you can see plants form the basis of the energy supply for all animals.
plants: sunlight for photosynthesis animals: plants, other animals
because they need to and it is the cycle of life
