Entropy is defined as the increase in disorder in a system. This occurs in the food chain because as animals eat food, they supply less energy to the next level of the food chain. What does this mean? Think of a rabbit. The rabbit eats almost all day, everyday. The energy in the grass is in an ordered state but becomes disordered as it goes though the rabbit. This is because the rabbit does things like cellular respiration, and gives off heat (this is wasted energy -- disorder). So out of the total amount of energy that flows through the rabbit only about 10% of this energy goes on to a fox that eats a rabbit due to all of this wasted energy. Cheers!

Answer from: Quest

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

Look at the pendulum diagram between which points does the pendulum’s potential energy increase most

Answer from: Quest

B, if it was a lower watt she could put it in for her normal time and not burn it

Alinearly polarized electromagnetic wave has an average intensity of 196 w/m^2. this wave is directed towards two ideal polarizers (in real polarizers, transmission is also effected by reflection and absorption). polarizer a is oriented with its transmission axis at an angle of θ_1=20.8∘ with the incident electric field. polarizer b has its axis at an angle of θ_2=63.0∘ with the incident electric field. what is the average intensity of the wave after it passes through polarizer a? what is the average intensity of the wave after it passes through polarizer b? suppose that the two polarizers a and b are interchanged. what would the average intensity be after passing through both polarizers?

Because air contracts as it cools, the air pressure inside a freezer is typically lower than on the outside. why do ice cubes inside a freezer tend to shrink over time? a. the ice dissolves oxygen from the air, forming a denser crystalline matrix.b. the ice reacts chemically with carbon dioxide in the air, forming gaseous carbon compounds.c. the ice melts, and then the liquid freezes as ice crystals on the bottom of the freezer.d. the ice sublimes, and then the water vapor deposits as ice crystals on the sides of the freezer.
