Yes they do, true
Food provides nutrients and energy we need.
It supplies us with calories. Calories are needed to keep the body temperature right and gives us energy to do things.
heterotrophs
Enzymes allow many chemical reactions to occur. They catalyze reactions by lowering the activation energy, which is the amount of energy needed to trigger a chemical reaction. Whereas heat can provide energy to trigger reactions, temperatures needed to reach activation energy for most metabolic reactions are often too high to allow cells to survive, so enzymes are in fact needed if metabolism (anabolic or catabolic) is to occur.
producers
To avoid wasting energy and resources on producing proteins that are not needed nor are already available.

Carbohydrates
energy
Those resources can be converted into whatever type of power is needed.
u need a source of energy.
Yes they do, true
The person using the hand tool supplies the energy needed to use it. That person gets energy from the food he eats.
Organisms need to carry out the process of respiration because the cells in the organisms break down simple food molecules and release their energy.
There is a limit to available resources and all organisms in an ecosystem compete for those resources. Those that are better adapted, will obtain higher amounts of those resources leaving less for those that do not have the best abilities. These organisms that did not obtain all the resources they needed will die therefore controlling population growth.
