Based on the information given in the video, the correct answers are:
a. The kelp population would increase because fewer large fish would be available to consume it.
The video explains that sea otters help control the population of large fish that eat the kelp. With a dramatic increase in the sea otter population, there would be fewer large fish available to consume the kelp, leading to an increase in the kelp population.
d. The kelp population would decrease because more sea urchins would be present to consume it.
The video also mentions that sea otters help control the population of sea urchins, which are a natural predator of the kelp. If sea otters were removed, there would be an increase in the sea urchin population, which would lead to a decrease in the kelp population.
For the second question:
d. There would be a decrease in kelp.
If abalone were removed from the system, there would be an increase in the population of sea otters, as mentioned in the video. This increase in sea otter population could lead to an increased consumption of kelp, resulting in a decrease in the overall kelp population.
Based on the information given in the video, how do you predict that a dramatic increase in the sea otter population would affect the kelp population?
a. The kelp population would increase because fewer large fish would be available to consume it.
b. The kelp population would increase because fewer sea urchins would be present to consume it.
c. The kelp population would decrease because more sunflower stars would be available to consume it.
d. The kelp population would decrease because more sea urchins would be present to consume it.
5. The video discussed the effects of the removal of sea otters on the system. What do you predict would be the most likely effect if you removed abalone instead?
a. There would be a decrease in sea otter populations.
b. There would be an increase in sea otter populations.
c. There would be an increase in octopus populations.
d. There would be a decrease in kelp.
