This theory has little evidence to back it up and many articles have shown studies that longer necks are preferred in sexual selection and therefore are more often the males that females choose to reproduce with. Changes have somewhat affected giraffes over time, however, it has been said that giraffes get their long necks from needing to reach higher when lower food is scarce. The changes are often due to species in the environment, and then the changes in the environment then change the species. This effects the environment as it changes how the ecosystem looks and its contents as well. The two types of succession, primary and secondary, make many different species of environments-many species with lots of variation. Succession: Succession is defined by as “the process by which the structure of a biological community evolves over time”. Therefore, without the nutrient cycle, giraffes could not survive because plants would not be able to grow. The nutrient cycle is very important to giraffes because they are herbivores. Lions are then at the top at they are known to be the giraffe’s biggest and most dangerous predator. Giraffes are next, in the middle of the chain,or, a pyramid. This plant life again often includes leaves from the acacia tree. As you can see, the leaves and plant life that giraffes consume are at the bottom. Another predator to giraffes is the crocodile, which often attacks only the calves when they are drinking from a body of water as the adults are very tall and intimidating.įlow of Energy: The food chain that includes giraffes is shown in picture B. According to, while adults aren’t killed too often thanks to their tall stature, half the number of a mother’s calves will be killed in a year. There are few predators to the reticulated giraffe, however one common predator would be a lion. However, because of their height, giraffes can adapt to many different types of woodlands with tall plants to eat from. Giraffes are usually found in savannas, especially those that have acacia trees as this is the type of plant they typically eat.
As you can see in picture A, these herds consist of many giraffes- up to about forty animals in a single herd.
Interdependence: According to, giraffes live in herds.
Scientific Name: Giraffa camelopardalis reticulata
