Question

many organic farming methods employ nonchemical means of controlling weeds and pests. often, these methods are not as effective, and so the trade - off for being chemical - free is a lower crop yield and higher prices. in which ecosystem would you expect to see greater diversity? multiple choice a cultivated field with herbicides a cultivated field with organic methods a cultivated field with pesticides a hydroponic garden (grown in a liquid medium in a greenhouse)

Explanation:

Organic farming methods use non - chemical means for pest and weed control. Chemicals like herbicides and pesticides reduce biodiversity by killing non - target organisms. Hydroponic gardens in greenhouses have a controlled environment with limited natural species. A cultivated field with organic methods is more likely to support a wider range of organisms compared to the others as it avoids harsh chemicals that can decimate populations.
