Question

Bergmann's rule

A. States that a linear body with long arms and legs is optimal for cold climates.
B. Concerns the relationship between climate and shape and size of appendages.
C. States that bodies with increased mass or volume to surface area are optimal for cold climates.
D. Is based upon the principle that as arms increase in length, there is a corresponding increase in surface area.

Answer 1

Bergmann's rule states that larger organisms are found in colder environments and smaller organisms are found in warmer environments. This rule is based on the principle that larger organisms have a smaller surface area to volume ratio, allowing them to retain heat more efficiently in cold climates.

Step-by-step explanation:

Bergmann's rule is an ecogeographic rule that states within a broadly distributed taxonomic group, populations or species of larger size are found in colder environments, whereas populations or species of smaller size are found in warmer environments.

This rule is based on the principle that larger organisms have a smaller surface area to volume ratio, allowing them to retain heat more efficiently in cold climates.

For example, polar bears are larger in size compared to their relatives in warmer climates, helping them adapt and survive in the cold Arctic environment.
