3. Keystone species
Keystone species are species that have a disproportionate impact on the ecosystem relative to their abundance. They play a critical role in maintaining the structure and function of the ecosystem, and their removal can have cascading effects on the entire food web.
- Example: Lions in the African savanna
Lions are a keystone species in the African savanna. They prey on large herbivores, such as zebras and wildebeest. By doing so, they help to keep the population of these herbivores in check. This, in turn, allows the vegetation in the savanna to flourish. Without lions, the savanna would be overrun by herbivores, and the vegetation would be destroyed. - Example: Elephants in the African rainforest
Elephants are a keystone species in the African rainforest. They eat a variety of plants, including trees, shrubs, and grasses. By doing so, they help to create clearings in the rainforest, which allows sunlight to reach the forest floor. This, in turn, allows new plants
to grow, and it increases the diversity of the rainforest ecosystem. Without elephants, the rainforest would be much denser, and there would be less diversity of plant life.
Keystone species are essential for the functioning of African food webs. Their removal can have a devastating impact on the entire ecosystem. It is therefore important to protect keystone species and their habitats.
4. Resilience
African food webs are relatively resilient to change, which is important in the face of climate change and other environmental challenges. This resilience is due to a number of factors, including the diversity of African food webs, the complexity of African food webs, and the presence of keystone species in African food webs.
- Diversity: African food webs are very diverse, with a wide range of plant and animal species. This diversity provides a buffer against environmental change. When one species in a food web is lost, another species can often take its place. This helps to keep the food web stable and functioning.
- Complexity: African food webs are complex, with many different trophic levels. This complexity also provides a buffer against environmental change. When one species in a food web is lost, there are often multiple other species that can fill its role. This helps to keep the food web stable and functioning.
- Keystone species: African food webs often have keystone species, which are species that have a disproportionate impact on the ecosystem. Keystone species play a critical role in maintaining the structure and function of the food web. Their removal can have cascading effects on the entire ecosystem. Keystone species can help to make food webs more resilient to change. For example, lions are a keystone species in the African savanna. Lions prey on large herbivores, such as zebras and wildebeest. By doing so, they help to keep the population of these herbivores in check. This, in turn, allows the vegetation in the savanna to flourish. Without lions, the savanna would be overrun by herbivores, and the vegetation would be destroyed.
The resilience of African food webs is important in the face of climate change and other environmental challenges. Climate change is expected to have a significant impact on African ecosystems, including changes in temperature, precipitation, and sea level. These changes could lead to the loss of some species and the decline of others. However, the resilience of African food webs could help to mitigate the impacts of climate change. By understanding the factors that contribute to the resilience of African food webs, we can better protect these ecosystems from the impacts of climate change and other environmental challenges.
5. Importance for humans
