The 10% rule means that approximately there will be only 10% energy transferred from a trophic level into another. That was because the consumer on the upper level will use the energy before it was consumed. About 90% of the energy used so only 10% remain will be transferred.
Example: an antler eating grass with a total 100 calories. Then the antler is moving and growing, using 90 calories. Then a lion eats the antler, but the energy remains is only 10 calorie because 90 calories are already used.

Answer:
soilds - close together arranged in a regular way
liquids - close together arranged in a random way
gases - far apart arranged in a random way
Explanation:
So,
Recall Newton's Second Law of Motion: force = mass x acceleration
Also recall:
acceleration = velocity/time
velocity = distance/time
Distance is expressed in meters.
Time is expressed in seconds.
Mass is expressed in kilograms.
v = m/s
a = m/s^2
F = m * a
F = kg * m/s^2

The unit for force is the Newton (N).
