Question

As per the conclusion drawn from the graph, what happened to the seal population as the whale population increased?

Option 1: The seal population increased.
Option 2: The seal population decreased.
Option 3: There is no correlation.
Option 4: The seal population remained constant.

Answer 1

As the whale population increased, the seal population decreased.

Step-by-step explanation:

Based on the graph, as the whale population increased, the seal population decreased. This suggests a negative correlation between the two populations. This could be due to increased competition for resources or predation by whales on seals.

Answer 2

As the whale population increased, it is inferred that the seal population decreased due to ecological pressures similar to those that arise from a decline in food sources. Therefore, the correct option is 2.

Step-by-step explanation:

The link between the populations of seals and whales is the subject of the inquiry. It is obvious from the statements and options given that, in this scenario, the seal population would not grow or stay the same if the whale population rose.

It is reasonable to assume that a similar ecological pressure, such as an increased whale population (assuming whales are competitors or predators of seals) could also result in a decrease in the seal population based on the excerpts provided, which suggest that a decline in food sources due to pollution or overfishing would lead to a decrease in the seal population (Option a).

Thus, Option 2—that is, a drop in the seal population—would be the appropriate conclusion to reach.

Therefore, the correct option is 2.
