Final answer:
Comparing the Arctic Fox from the tundra to the Camel from the desert illustrates how different environments lead to distinct evolutionary adaptations for survival.
Step-by-step explanation:
Comparing organisms from contrasting environments such as the tundra and the desert provides insight into how species adapt to their specific biomes. An example for such a comparison would be the Arctic Fox (Arctic tundra resident) and the Camel (desert resident). The Arctic Fox is well-adapted to its cold environment with insulating fur and a compact body shape to minimize heat loss, while the Camel has evolved features such as the ability to tolerate water deprivation, heat and store fat in its hump to survive in the arid desert environment.
These species highlight how different environments shape the evolution of species to create unique adaptations. Thus, when selecting organisms to compare in a paper focused on environmental adaptations, an ideal pairing is one like Option C: Arctic Fox and Camel, representing two distinct biomes with starkly different climate challenges.
