Animals require energy to support the processes of life: movement, foraging, digestion, reproduction, growth, work. Organisms can be categorized into one of the following groups:
The energy that fuels their life all comes from the Sun as sunlight. This is trapped by plants who use it to make sugars. All animals survive by eating plants (and thereby stealing the plants sugars/energy) or each other. This is the basis of what is known as the "food chain".
Animals (which include humans!) get their energy from the food they eat.
They get their energy from their food.
Animals obtain their energy from the consumption of plants or other animals.
obtain energy from nucleas
Animals obtain their energy and carbon from the food they ingest. Carbohydrates and protein are a good source of carbon and energy.
simples. sun get enery from plants, animals get energy from plants. we eat plants and animals so we obtain energy
Animals obtain energy by what they eat. It is all a big cycle, the sun(main source of energy) gives energy to the grass which gives energy to the cow, though in smaller amounts.
from the food they eat.
by eating them
Wolverines obtain energy from the animals they consume.
Animals.
As autotrophic animals are producing their food by themselves using light energy(solar energy) due to presence of pigments chlorophyll ,so they are independent while hetrotrophic animals doesn't have chlorophyll and obtain their nutrition from autotrophic or animals(they are dependent).therefore,
Basically, all animals get their energy from the food they eat.
Photosynthesis gives plants energy, and when animals eat the plants, they gain energy from the plants. And, of course, when animals eat other animals, they indirectly obtain energy from the plants, which get their energy from the sun. So, the answer would be the sun.
