Question

Quizplus · Accepted Answer

Plant productivity is greatest in natural ecosystems with high biodiversity because more species means more efficient use of resources and greater nutrient cycling. This leads to increased plant growth and productivity. Conversion of natural ecosystems into cropland or the presence of invasive species can actually decrease overall productivity by reducing biodiversity and disrupting nutrient cycling. Presence of endemic species may or may not contribute to plant productivity, depending on their role in the ecosystem.
