No, chemical reactions are not the only reactions that may involve absorption of energy. A physical change like heating water to vapor is also endothermic.

Is more energy absorbed than released is the result of an endothermic chemical reaction?
In an endothermic reaction, heat is taken in from the environment. Heat is a form of energy. Therefore, energy is taken in, i.e. absorbed.
What is a chemical reaction in which more energy is taken in than given off?
Exothermic Reaction
What evidence is there to show that a chemical reaction has taken place when an egg is cooked?
The change in color indicates that a chemical reaction has taken place.
What is a reaction which takes in energy?
endothermic
A reaction in which energy is taken in?
base
Can energy be taken only during a chemical reaction?
Depending on the particular chemical reaction, energy may be either released or absorbed.
Does energy decrease or increase during a chemical reaction?
Energy is only made not taken away. But during a chemical reaction, it depends on what kind of chemicals you put in there.

What is a chemical reaction in which more energy is given off than taken in?
Combustion, burning, releases more heat that is taken in to start the reaction.
What is a chemical reaction in which more energy is taken in than given off?
Exothermic Reaction
What two things can happen to energy in a chemical reaction?
well you see now, a lot of things can happen. 1. the chemical reaction will slow down because of the energy being wasted. 2. the chemical reaction will not work anymore because it was wasted and now has no energy. HOPE THAT HELPED
What is difference between released chemical energy and absorbed chemical energy?
When chemical energy is released, it is released to the environment in the form of heat. This heat can be felt and measured. When a reaction results in an increase in temperature, energy has been released (it gets hot), and you have an exothermic reaction. When chemical energy is absorbed, it is taken from the environment. This causes a decrease in the temperature of the surroundings. Energy has been absorbed from the environment around the reaction (it gets cold), and you have an endothermic reaction.
What changes gives NO evidence that a chemical reaction has taken place?
Physical changes give no evidence that a chemical reaction has taken place, because no chemical reaction has taken place.
What is A reactant in which energy is taken in?
You probably mean "what reaction releases energy," in which case, lots. Reactions that release energy into the environment are called exothermic reactions. An example of which would be mixing sodium (Na) and water (H2O) to form sodium hydroxide (NaOH), hydride (H2), and heat/energy. 2Na + 2H2O ---> 2NaOH + H2 + heat/energy
