Question

⦁ Nana Sampene is a big-time farmer at the Bono Region. He uses a novel insecticide called pirimiphos methyl. He religiously applies the insecticide as instructed by the manufacturer and loses approximately 25% of his cashew to insect pests. Nenyi Nkensen, another big-time farmer who farms at the Awutu Senya West District, hears about this outcome, and therefore decides to use thrice as much of the pirimiphos methyl and loses only 5% of his cashew to insect pests. Each of these two farmers decides to maintain this pattern of insecticide application for seven years. At the end of the seven years, Nana Sampene is still losing 25% of his cashew to insect pests but Nenyi Nkensen is losing 45% of his plants to insect pests. Is it possible for these observations to be elucidated on the basis of natural selection? Explain
