Effects on the environment when species extinct?

1. Disruption of food webs and ecosystems:

- Extinction of a species can lead to the loss of a food source for other species.

- This can have a ripple effect throughout the ecosystem, affecting predator and prey populations.

2. Loss of biodiversity:

- Reduced biodiversity can make ecosystems more vulnerable to environmental changes, such as climate change and pollution.

3. Spread of invasive species:

- The extinction of native species can create opportunities for non-native species to invade an ecosystem.

- Competitive invaders can alter the structure and functioning of the ecosystem.

4. Loss of ecosystem services:

- Many ecosystems services, such as pollination and water purification, depend on the presence of specific species.

- The loss of species can lead to the decline of these crucial ecosystem services.

5. Alteration of biogeochemical cycles:

- Certain species play vital roles in regulating biogeochemical cycles, which are essential for maintaining the balance of nutrients and energy in the environment.

- Extinction of these species can disrupt biogeochemical cycles with cascading impacts.

6. Impact on human societies:

- Many species provide resources that are directly or indirectly used by humans, such as food, medicine, and materials. Extinction can diminish these resource.

- Disruption of ecosystems and climate regulation can also have negative consequences on human economies and livelihoods.
