Which ecosystem best matches the following description?
found at high altitudes, the harsh climate allows only species that are adapted to the changing environment to survive.
alpine
desert
tundra
deciduous forest

The correct answer is A. Alpine

Explanation:

Alpine ecosystems are located between 11000 to 11500 feet high in which strong winds and cold temperatures prevent many species to survive including trees. Only small shrubs, sedges and grasses and animals such as mountain goats, marmots and other adapted to the cold temperature and the strong winds survive in this ecosystem. This implies, this ecosystem is located at high altitude and has a harsh climate with few species able to survive in it, and thus the correct answer is Alpine.
