On a hot day, water in a bucket gets warmer than water in a small swimming pool. What does this observation tell you about temperature changes when different amounts of the same material are heated?

Small amounts of a material are more likely to be affected by temperature, than bigger amounts of the same substance.

Explanation:

This is because of heat capacity. Heat capacity is the the amount of heat needed to raise the temperature of 1 gram of a substance by 1 degree. Water has a very high heat capacity, so the more of it there is, the harder it il be to raise its temperature.

it's anything that aren't producers and consumers.

explanation:

you've got to be clear on what "this" is

well, that's easy; the answer's c, "it reduces contamination of the water and substrate of the estuary."
