The primary food source for a giraffe consists mainly of leaves, particularly those from acacia trees. Giraffes are herbivorous and possess a long neck that allows them to reach high branches where other herbivores cannot. Their specialized teeth and tongue, which can be up to 18 inches long, help them grasp and strip leaves effectively. Additionally, giraffes consume fruits and flowers but rely heavily on foliage for their nutritional needs. This diet is essential for their growth and health, allowing them to thrive in their natural savanna and woodland habitats across Africa.
