Question

which of these species is extinct/endangered because of low reproductive rate?
rabbits
lionfish
gray whales

Explanation:

Gray whales have a relatively low reproductive rate. They have a long gestation period (about 13 - 14 months) and typically give birth to one calf every 1 - 2 years. This low reproductive rate makes them more vulnerable to population declines compared to rabbits (which have a high reproductive rate, with multiple litters per year and several offspring per litter) and lionfish (which also have a high reproductive capacity, with females releasing thousands of eggs multiple times a year).

Answer:

Gray Whales
