Answer:
Their survival is correlated to water clarity because kelp, the main food of otters' prey (sea urchins), needs clear water to thrive.
Explanation:
Otters are extremely important organisms, also known as "<em>keystone</em>" species. They keep aquatic ecosystems healthy because they control other populations such as sea urchin populations that consume kelp, sometimes in excess.
For this reason, otters prefer inhabiting near the kelp, which generally grows in clear waters near shores. They also prey on crabs, marine snails, squid, etc. as they possess the ability to dive as deep as 250 feet.
Therefore, their survival is correlated to water clarity because kelp, the main food of otters' prey (sea urchins), needs clear water to thrive.

<span>The specific heat of the metal is 0.5 cal/ (0C.g). This means the energy needed is 0.5 cal to raise the heat of 1 gram of metal by 1 degree C. Therefore, the energy needed to raise 100 g of the metal by 20 degrees C is:
0.5 * 20 * 100 = 1000 cal.
