Final answer:
The relationship between biodiversity and food security is crucial. Crop diversity is necessary for a stable and nutritious food supply, and biodiversity provides essential ecosystem services that support agriculture. Loss of biodiversity can make food production more expensive or impossible, and the endangerment of wild food sources like fisheries also threatens food security.
Step-by-step explanation:
The relationship between biodiversity and food security is crucial. Crop diversity is necessary for food security as it ensures a stable and nutritious food supply. Biodiversity provides ecosystem services such as pollination, nutrient cycling, and pest control, which are essential for agricultural productivity. Loss of biodiversity threatens these services and can make food production more expensive or even impossible. Additionally, wild food sources like fisheries contribute to protein supply, but their ability to provide food is threatened by extinction.
