Answer:
Some of the things that worms eat include dead plants, live plants, dead animals, animal poop, and other microscopic animals. After they eat, they grind up and digest their food and pass the rest as waste, called castings, which go back into the soil and help plants grow and stay healthy.
Whale skeletons support so much life because they contain an enormous amount of oil. Before this happens, they must release enough eggs or larvae so that some tiny proportion will be transported by the ocean currents and survive until they can find and colonize another whale carcass.

Answer:
The stream will flow fastest between 2 and 3.
Explanation:
On this map, we can see two basic elements, one being the contour lines, and the other being the color with which a stream is presented. The contour lines are giving us a good representation of the relief and where it is steeper and where it is less steep. Basically, where the contour lines are closer to each other, we have a steeper relief, and when the contour lines are further away, the relief is less steep.
The water moves under the influence of gravity, so downward. Where the steepness is the greatest, the gravity influences it the most, so it moves faster, while where the steepness is smaller, the gravity influences it less, so it moves slower. On this map, the contour lines are closest to each other between points 2 and 3, meaning it is the steepest part of the relief, and it is the place where the stream flows the fastest.
