Use the table to complete the activity.

Population of Seals and Sea Lions
Type of Seal or Sea Lion Population Reproduction Rate
monk seal 1,100 low
northern fur seal 650,000 low
gray seal 290,000 high
leopard seal 220,000 to 440,000 medium
Australian sea lion 10,000 to 12,000 low
Which type of seal or sea lion is more likely to become extinct: the Australian sea lion or the northern fur seal? In one or two sentences, explain your reasoning.

(2 points)

Answer 1

The Australian sea lion is more likely to become extinct because its population is much smaller than the northern fur seal and its reproduction rate is low. This means that its population is not as sustainable and has a higher risk of decline or extinction.

Answer 2

The Australian sea lion is more likely to become extinct compared to the northern fur seal. This is because the Australian sea lion has a lower population (10,000 to 12,000) and a low reproduction rate, making it more vulnerable to threats and less able to replenish its population. Meanwhile, the northern fur seal has a higher population (650,000) despite also having a low reproduction rate, which suggests a greater likelihood of survival and avoiding extinction.

Answer 3

To determine which type of seal or sea lion is more likely to become extinct, we need to consider their population size and reproduction rates. The Australian sea lion has a population of 10,000 to 12,000, which is relatively low compared to the northern fur seal's population of 650,000. Additionally, the Australian sea lion has a low reproduction rate, further increasing its vulnerability. Therefore, based on lower population size and reproduction rate, the Australian sea lion is more likely to become extinct compared to the northern fur seal.
