Here is the correct matching of human activities with their effects on populations:
-
Removing trees from a forested area for the purpose of farming, building, or recreation
Effect: Habitat destruction, which can lead to decreased biodiversity and displacement of native species. -
Fertilizers get washed into bodies of water causing algae to grow quickly
Effect: Eutrophication, leading to oxygen depletion in water bodies and a decline in aquatic life. -
Purposeful or accidental introduction of non-native species into an area
Effect: Disruption of local ecosystems, competition with native species, and potential extinction of native populations. -
Protecting and preserving the environment
Effect: Conservation of biodiversity, restoration of habitats, and stabilization of ecosystem functions.
