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.) sin reseñas | añadir una reseña
Explains how the acacia evolved its own protection against browsing animals and helped create a balanced natural environment. No se han encontrado descripciones de biblioteca. |
