Population ecology is the study of these and other questions about what factors affect population and how and why a population changes over time. Population ecology has its deepest historic roots, and its richest development, in the study of population growth, regulation, and dynamics, or demography.
While running, the neck of a giraffe moves backward and forward to keep the animal balanced. Giraffes have a top speed of about 56 kilometres per hour (35 miles per hour), however, because its legs are so long a galloping giraffe does not appear to be going very fast.
Giraffes have many features which help them adapt to their habitat. One of these features is their long necks, which stretch almost 2 meters above their body. This helps them â¦ to get fruit and leaves high up in the trees. It also helps them to see far away.
