Which of the following is a possible advantage for the environment of having farmers use plants that genetically produce Bt toxin?
◦ Plants with genes for the toxin are eaten less often by insects, and therefore less insecticide is needed.
◦ Plants that produce Bt toxin must be grown from new seeds each season, and therefore fewer
of them are planted.
◦ Bt toxin is advantageous to many species of invertebrates that grow in the same fields.
◦ Harvesting plants with these genes is less disturbing to the soil layers where they are planted.
◦ Plants with these genes must be sprayed with the organism, but need much less than other plants.
