The correct option is HYPOTHESIS.
An hypothesis refers to an explanation, that is proposed and which is temporarily accepted in order to investigate an observed phenomenon. Sometimes it is described as educated guess.
Scientific hypothesis is the first step that is always taken by scientists during the course of scientific investigation and it serves as the basis on which the scientific investigation is based. A hypothesis must be testable and the explanation offered abut it must be based on prior scientific knowledge.
Answer:

Answer:
1. 39 J; 2. 3.9 % usable; 3. 96.1 % unusable
Step-by-step explanation:
1. Available energy
Energy consumed = 1000 J
Less waste = - 177 J
Less respiration = <u>-784 J
</u>
Total energy lost = <u>-961 J
</u>
Available energy = 39 J
2. Percent of total energy usable
The chipmunk could use only 39 J of the original 1000 J.
% of energy usable = 39 J/1000 J × 100 % = 3.9 %
3. Percent of energy unusable
The chipmunk lost 961 J of the original 1000 J.
% of energy unusable = 961 J/1000 J × 100 % = 96.1 %
