So how the acacia bush learned to protect itself, or, rather, how a balance was achieved between the acacia bushes and the giraffes. (Also mentions rhinoceroses as eaters of acacia bushes, but not ones that eat enough at one time to harm a bush, hence no protection was needed against them.) ingen anmeldelser | tilføj en anmeldelse
Explains how the acacia evolved its own protection against browsing animals and helped create a balanced natural environment. No library descriptions found. |
