Final answer:
Polar bears live in Arctic ecosystems, oxen can be found in grasslands and tundra, beavers inhabit freshwater ecosystems, and camels adapt to desert ecosystems. Biodiversity is crucial for these animals' survival and habitats.
Step-by-step explanation:
The type of ecosystem in which the following animals would live are as follows:
- Polar bear: Lives in the Arctic ecosystem, particularly on the sea ice, where they hunt for seals.
- Ox: These large bovines are found in various ecosystems, including grasslands and tundra, where they graze on grasses and other vegetation.
- Beaver: Beavers are found in freshwater ecosystems such as rivers, streams, and ponds, where they build dams and lodges.
- Camel: Camels are well-adapted to live in desert ecosystems, where they can survive with limited water.
Understanding where different animals live is essential for their conservation and to maintain biodiversity.
