Why does much of Antarctica’s wildlife live in the environment shown?

A.
Human settlement in Antarctica has wiped out most native land-dwelling animals.

Antarctica is barren with little vegetation, so much of its wildlife depends on the sea for food.

C.
Climate change in recent years has made the land surface in Antarctica uninhabitable.

D.

Answer 1

Antarctica is home to many unique and specialized species that have adapted to survive in its extreme environment.
The continent's harsh conditions, including its frigid temperatures, intense winds, and long periods of darkness, have shaped the evolution of its inhabitants. For example, penguins have developed thick layers of fat and waterproof feathers to keep warm and dry, while seals have adapted to spend long periods of time underwater, conserving energy and avoiding predators. Additionally, many species in Antarctica rely on the ocean for food, which is abundant in nutrients due to upwelling currents and the melting of sea ice. Overall, the survival of these species in Antarctica is a testament to the incredible resilience and adaptability of life on our planet.
