Explanation:
In an ocean ecosystem, many types of fish and turtles are herbivores that eat algae and seagrass. Sea urchins are powerful primary consumers in kelp forests.
The formula for finding the kinetic energy of an object is:
KE = 0.5MV^2,
Where:
M= Mass
V = Speed
From the information given above,
M = 21 kg
V = 3 m/s
KE = 0.5 * 21 * 9 = 94.5
Therefore, the canoe's kinetic energy is 94.5 J
Its stabilising. Since the selection pressure is against the extremes which are the normal blood and the sickle cell anaemia.
