Question

A highly competitive plant has a specialist insect herbivore that could limit its growth. Scientists test the effect of the herbivore on the plant's competitive ability by killing the herbivore with pesticides in some plots to compare with plots that were not sprayed with pesticide. Which of the following outcomes are expected for this experiment? O A Lower herbivore populations in plots that were sprayed with pesticide B Herbivores consume more of the competitive plant in plots that were not sprayed O C Inferior competitors become more abundant in plots that were not sprayed O D All of the above are expected outcomes

Answer 1

A. lower herbivore populations in plots that were sprayed with pesticide, This is the correct expected outcome because if pesticide is sprayed then pesticide kills herbivore and eventually their population decreases Herbivere consume more of the competitive plant in plots that were not sprayed This option is correct because if plots were not sprayed then Herbivere increases and more hertivone consume more plant. → B C. Inferior competitors become more abundant in plots that were not sprayed. This option is also consect. without besticid sprayed, Herbivore number increases and Haube pore consume more competitive plant. So, Growth of competitive plant become limited, it leads to increment in the number of inferior competitess of plants. All of the above are expected outcomes → D. So, option (1) is connect.
