<span>A protonephridia is known as a flame cell because it is a specialized excretory cell. This simply means that these cells have the ability to remove waste materials within an organ of a particular living organisms.

What is the relationship between water clarity and otter survival?
creativ13 [48]

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.

LUCKY_DIMON [66]

Answer:

The tryptophan synthase enzyme catalyzes the synthesis of tryptophan. This enzyme is found in all kingdoms except animals.

If one million kilocalories of energy are stored in producers in an ecosystem, how many kilocalories can be transferred to terti
Mashcka [7]
The answer is 1000 kilocarolies.  It is important to keep in mind that Energy is passed up the food chain from one trophic level to the next but a lot of it is lost along the way. Energy is passed up the food chain from one trophic level to the next. However, only about 10% of the total energy stored in organisms at one trophic level is actually transferred to organisms at the next trophic level. Therefore; if the producers have 1 million kilocarolies, then  the energy transferred to the primary consumer will be 100,000 kilocalories (10% of a million), and the energy transferred to the secondary consumer will be 10,000 kilocalories (10% of 100,000) and the energy to the tertiary consumer will be 1000 kilocarolies (10% of 10,000).
