A) porpoise

B)dolphin

C) manatee

D) whale​

Answers

Answer:

C) manatee

Explanation:

According to Wikipedia, "Cetaceans are aquatic mammals constituting the infraorder Cetacea. Key characteristics are their fully aquatic lifestyle, streamlined body shape, often large size and exclusively carnivorous diet."

The most important thing to note here is the part saying "exclusively carnivorous diet." Manatees are aquatic mammals with a fully aquatic lifestyle and large size, but they are not carnivorous. Manatees feed on water grasses, weeds, and algae, according to National Geographic. So, manatees are not cetaceans.

In the northern hemisphere, when does the phytoplankton biomass peak in the polar region? why?

Answers

Given what we know about phytoplankton biomass peaks in the polar region of the northern hemisphere, we can confirm that this occurs in the spring.

As the polar regions are tilted away from the sun, days there are short, sometimes these regions even enter month-long periods of darkness. Due to this, sunlight is not always strong enough to penetrate deep into the water.

In the Northern Hemisphere, the phytoplankton biomass peaks in the spring given that during this time the sun is high enough in the sky for sunlight to penetrate deep into the water and provide a food source for the plankton to thrive.
