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 %
