Final Answer :
B
Explanation :
Natural ecosystems have evolved over time to be self-sustaining and capable of self-renewal through various ecological processes such as nutrient cycling, water cycling, and predation. While they may be subject to invasion by pathogens and weeds, they also have mechanisms to cope with these challenges without the need for pesticides. It is rare for a natural ecosystem to have most of its biomass in one species as biodiversity is a key characteristic of healthy ecosystems.
