Energy is destroyed because animals are higher levels do not need as much energy. That is option B.
<h3>Energy movement in a food chain</h3>
Food chain is defined as the sequence that shows the feeding relationship between different organisms and how energy flows from the producers to decomposers.
The producers which are the plants traps in energy from the sunlight with the help of their green pigment called the chlorophyll.
The energy continuously flows from the producers to consumers and then to the decomposers.
From the law of conservation of energy, it is neither created nor destroyed.
Therefore energy is destroyed because animals at higher levels do not need as much energy, is not a valid statement.

A)
R1 = 30/(7*60)
We are multiplying 7 with 60 because there are 60 seconds in 1 minute.
R1 = 30/420 = 0.0714 gallons/second
b) For this we need to express gallons to cubic meters.
1 gallon = 0.003785 m^3
R2 = 0.0714*0.003785 = 0.00027 m^3/s
c) V = R2*t where V is volume of some tank.
which means that
t=V/R2
t = 3698.8s or
t = 1.0274 hours
Answer:
Temperature, density
Explanation:
Physical properties of a substance are those properties that do not change the chemical composition of the substance. There are two types of physical properties namely: intensive property and extensive property.
Intensive properties are those physical properties that does not depend on the sample size of the substance involved. Examples of intensive physical properties are temperature, density, boiling point. For example, the size or amount of a substance does not determine the the TEMPERATURE or BOILING POINT of the substance.

Answer:
Work hasn't been done by Michael because no distance was covered.
Explanation:
Workdone is given by the formula;
Where;
W is the work done
F represents the force acting on a body.
s represents the distance covered by the body.
Hence, work hasn't been done by Michael because no distance was covered, as the table didn't move at all. Therefore, work done is zero.
