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.
Autotrophs.
Every living organism are respiring.They respire in order to generate energy
Some organisms perform photosynthesis to produce energy other organisms cannot do photosynthesis what can they do in order to generate energy?
We will generate more energy this year.Britain seeks to generate 100% of their energy from renewable sources.I hope this will generate interest in the book.
There are no animals that perform photosynthesis but there are a group of bacteria called cyanobacteria that rely partially on photosynthesis to generate metabolic energy.
A digestive system like what you're referring to is only found in animals. In order for animals to survive they have to eat. This consists of either plants or other animals in order to get the energy and nutrients that they require to live. Plants on the other hand, generate their own energy. They use water and various nutrients from the soul along with chlorophyll and sunlight in order to grow. The combination of these factors in a chemical reaction creates the energy that they need. Therefore, they don't have a digestive system like that which you are referring to.
No, elephants are animals. Animals are consumers, that is they get their energy from outside, form their food. Producers are those organisms which can generate their own food, and are nearly always green plants.
Mitochondria generate energy through the process of aerobic cellular respiration.
It takes energy to generate electricity. Mechanical energy or thermal energy or nuclear energy , chemical energy,etc, etc,etc
The main energy source used in cellular respiration, particularly in animals, is glucose. It is the common energy source cells use in respiration to generate ATP.
To generate an alternating current, a magnet must use kinetic energy. This means that the magnet must move at a certain speed and velocity in order to create a strong enough energy charge.
It normally is not very hard to generate renewable energy. Sometimes it is, depending on how you are generating renewable energy.
