food.
No. Neither can plants, for that matter. Animals get the energy they need from plants, or from other animals, which they eat. Plants get their energy from the sunlight.
Animals get all the energy they need from the food they eat.
polar bears need to live, so they have to get energy from other animals.
I am not entirely sure what you mean by "generate"; technically they don't "generate" it. Animals get the energy they need from the food they eat.
Plants need sunlight to produce sugars which they use for their nutrition. Then herbivore animals eat the plant to get energy and after that the carnivore animals eat the herbivore animals for the same reason. The energy of sunlight has traveled through plants, herbivores and carnivores, for example to humans who eat other animals.
Their food, directly. As that food is either plants, or animals that eat plants, or animals that eat animals that eat plants, and so on, every animal indirectly gets its energy from the sun.Save for animals around thermal vents in the ocean depths, of course, those ultimately get it from warmth and minerals.
The energy source is the sun. Plants use solar energy to produce the foods they need for growth. Animals feed on the plants or feed on animals that eat plants.
All animals need sunlight to be active, weather directly or not. For example animals who eat plants need sunlight to make the plants that they eat to get energy. For meat eaters its a bit more complicated. They eat the animals who eat plants who use the sun. so indirectly all animals need sunlight.
Herbivores are animals that lived only on vegetables. This class of animals need a lot of energy and for this reason they can eat all day long. Example of this type of animals are cows and sheep.
animals get energy from the food they eat that gives them energy
Animals (and humans) get their energy from the food they eat.
