1) King penguins are flightless aquatic birds found primarily in the Southern hemisphere. They live as a large colony and have highly social interactions. King penguins begin reproducing at six years of age and lay one or two eggs per reproductive cycle.
Males and females share the incubation duties and raise the chicks together for about 15 months. When the young penguins get older, they form a large group guarded by only a few adult penguins, allowing the parents to forage for food without having to worry about their young.
As a population, penguins could be classified as
a. K-selected because they live in a large colony
b. r-selected because only a few adult penguins care for the young penguins
c. r-selected because of the relatively long breeding cycle
d. K-selected because they only lay one or two eggs per reproductive cycle
2) Atlantic bluefin tuna can reach 450 kg in weight and have high commercial value in the restaurant industry for sushi and sashimi.
Although they can live up to 50 years, the bluefins reach maturity around 8 years of age and spawn once a year, releasing approximately 30 million eggs each.
The bluefins tend to swim together in large groups and migrate thousands of miles across the Atlantic ocean. There are two known spawning locations: the Gulf of Mexico and the Mediterranean Sea.
As a population, tuna could be classified as
a. K-selected because they are migratory fish
b. r-selected because they only spawn in two specific locations
c. K-selected because they are schooling fish, grouping together
d. r-selected because they release 30 million eggs per female
