Final answer:
When populations are lost from a community, there are consequences for that species. These consequences include disruptions in the ecosystem, loss of biodiversity, and potential collapse of food chains or trophic cascades.
Step-by-step explanation:
When populations are lost from a community, there are consequences for that species. These consequences include disruptions in the ecosystem, loss of biodiversity, and potential collapse of food chains or trophic cascades. For example, the loss of a keystone species can have a profound impact on the entire community, as they play a crucial role in maintaining the balance and stability of the ecosystem. Additionally, the loss of species can also impact human welfare, such as the loss of medicinal plants or the collapse of important ecosystems that support human livelihood.
