What aspect of agroecology supports biodiversity?

The aspect of agroecology that supports biodiversity is rooted in ecological principles in agricultural practices. Agroecology emphasizes the integration of diverse crops, animals, and natural pest control, creating a balanced ecosystem that enhances the resilience of agriculture. By incorporating a variety of species and agricultural methods that mimic natural ecosystems, agroecology fosters a habitat for various organisms, promoting a richer variety of plant and animal life.

This approach encourages practices like crop rotation, intercropping, and agroforestry, all of which enhance soil health, reduce pest populations naturally, and improve resilience to climate change. Such practices not only support biodiversity but also lead to more sustainable food systems by improving ecosystem services, such as pollination, nutrient cycling, and pest management.

In contrast, the other choices do not support biodiversity effectively. Monoculture practices involve growing a single crop over a large area, which decreases genetic diversity and makes crops more susceptible to pests and diseases. The use of chemical pesticides can harm non-target species, including beneficial insects, thereby reducing biodiversity. Lastly, heavy reliance on fossil fuels contributes to environmental degradation, which can severely impact habitats and the biodiversity they support.
