In an ecosystem, the average temperature increases, causing a shorter winter. There are two varieties of rabbits in this area: white-furred rabbits and brown-furred rabbits. Which scenario is most likely?
In an ecosystem, the average temperature increases, causing a shorter winter. There are two varieties of rabbits in this area: white-furred rabbits and brown-furred rabbits. Which scenario is most likely?
A. Both white- and brown-furred rabbits increase. B. Both white- and brown-furred rabbits decline. C. The proportion of white-furred rabbits in the population declines. D. The proportion of white-furred rabbits in the population increases

Answer 1

C. The proportion of white-furred rabbits in the population declines.

As the average temperature increases and winters become shorter, the environmental conditions may favor the brown-furred rabbits. Brown fur provides better camouflage in a warmer environment with fewer snowy conditions, making it easier for them to hide from predators. In contrast, white-furred rabbits may have a disadvantage due to their coloration not blending in well as the snow cover diminishes, potentially leading to a decline in their population or a decrease in their proportion relative to the brown-furred rabbits.
