AQA Science Exam Question and Answer
Question:
Define a "caribou" and describe one of the unique adaptations that help it thrive in its natural habitat.
Answer:
A "caribou" is a species of large, Arctic and sub-Arctic deer, also known as "reindeer" in Eurasia.
Unique Adaptation of Caribou:
One unique adaptation of caribou is their seasonal migration. During harsh winters, caribou undertake long-distance migrations, covering hundreds of miles, to seek food and access more favourable habitats. This migration allows them to avoid extreme weather conditions and find sufficient food resources in different regions throughout the year. The ability to undertake such extensive migrations is a remarkable adaptation that helps caribou survive in their challenging and ever-changing Arctic environments, where food availability varies dramatically with the seasons.
