Final answer:
Habitat fragmentation negatively impacts ecosystems by negatively impacting all populations, resulting in loss of biodiversity and disruptions to species interactions and ecological processes.
Step-by-step explanation:
Habitat fragmentation negatively impacts ecosystems because it negatively impacts all populations. The destruction and fragmentation of habitats lead to a loss of biodiversity. Habitat destruction, fragmentation, and new forms of land use are closely intertwined in an overall process of landscape change. Habitat fragmentation also results in the isolation of populations, restricting immigration and emigration, which affects local populations. Additionally, habitat fragmentation disrupts species interactions and ecological processes, which vary between ecosystems and regions.
