In physics, energy is required for work to be performed.
If you have a machine that you want to just sit somewhere, it doesn't need any energy.
If you want a machine to actually do something, then it needs energy.
In space, a satellite can travel millions of miles without any added energy (just the energy required to set it on its path). In a sense, a form of perpetual motion.
On earth, true perpetual motion doesn't exist. If one doesn't want a machine to stop due to friction and other forces, then one must add energy.
Living beings and machines need energy to perform various functions and activities. Energy is required for metabolism in living beings to carry out processes like growth, repair, and movement. Machines need energy to power their operations and execute tasks efficiently.

What is the brief definition of energy?
Energy is the ability to do work or cause change. It exists in different forms such as kinetic, potential, thermal, and chemical energy. It can be converted from one form to another but cannot be created or destroyed.
What non living thing that require energy?
Vehicles, electronic devices, and machines are examples of non-living things that require energy to function. They need energy sources such as fuel, electricity, or batteries to operate and perform their intended tasks.
Why is there a need for energy transform from one another?
Energy transformation is necessary because different forms of energy are more suitable for different tasks. For example, electrical energy is required to power our devices, while mechanical energy is needed for transportation. By transforming energy from one form to another, we can ensure that we have the right type of energy for specific applications.
Why do living things need energy and where do they get it?
Living things need energy to carry out essential functions such as growth, reproduction, and movement. They get this energy from food sources, which provide molecules that can be broken down through processes like cellular respiration to produce ATP, the main energy currency of cells.
Do only humans need energy to survive?
All living creatures need energy to survive. Energy is anything that makes something move or change, not only carbohydrates in food like some people think. For instance, your heart needs energy to beat, and your brain needs energy to think. Animals, and even tiny organisms, need some sort of energy to survive.
Why do living things and machines need energy?
living things need energy because they cannot live longer without energy
Why does living beings need food?
because food gives us energy
What is the benefit of carbs?
Carbohydrates provide energy, which all living beings need.
Do you need to move and use energy to be considered living?
No. Using energy is indeed one of the characteristics which living beings are expected to have. Moving, on the other hand, only applies to SOME living beings - plants (and some animals, such as sponges) usually don't move, but are still considered living beings.
What will happen to living things if there is no heat energy?
All the living beings would die... All the humans and animals would die by freezing... Because we need heat.
What is life's need for energy?
Living beings are, in a way, similar to engines, and they need fuel - for example, to move around, to grow, etc. Without energy, no change is possible. A lifeless statue doesn't need energy; anything that moves, grows, or undergoes any other type of change, does.
Why is the sun necessary to all organisms in an ecoystem?
Second Law of Thermodynamics. Roughly speaking, to get ANYTHING done, you need to have available energy. All machines, but also all life forms, need energy.The Sun is the ONLY significant source of freely available energy here on Earth. Most other forms of energy (including wind, potential energy from falling water, etc.) derive from solar energy. The few other forms of energy are either not significant, or are difficult to access for living beings.
Do living thing need energy?
yes all living things need energy
Why do you need to water plants?
Plants need water; in fact, all living beings need water.
Why does cell respiration take place?
All living beings need energy to maintain there lives. Respiration is chemically oxidation of big molecules to release energy. This burning of fuel in a cell (or organism) is called respiration.
How air supports life?
All living beings need air to survive.
Do you find that all living being need same kind of food?
Do all living beings need same kind of food to eat
