If you mean "we humans" - we take in energy by the food we eat. That food contains chemical energy.
Energy has many forms. The energy that is stored in the position or the structure of an object is called potential energy . There are many forms that potential energy can take. Chemical potential energy , elastic potential energy, and gravitational potential energy.
Bacteria a re decomposers. They take energy from dead animals.
light energy
Electric motors take electric energy and turn it into kinetic energy Generators take mechanical energy and turn it into electric energy
they stick their snouts in and take the energy
It takes the energy of heat.
The plants take in energy by absorbing sunlight.
They obtain energy in much the same way as people do. They take organic matter called detritus, and take the chemical potential energy out of it.
Which energy?
Producer get their energy by the nutrients and the sun it gets.
they use the sun as energy which is their sugar and food.
Crystals do not give energy!
