Select from the dropdown lists to complete the text.

Biological control involves the introduction of ( living, deceased, large ) organisms into an area affected by ( drought, pests, humidity ). The biological controls ( attack and eat, feed and provide food for, ignore ) the pests, eradicating the issue from the area. However, if too successful, these controls can ( eliminate, increase, support ) the food supplies of native species. They may also attack the native species. If proper research is not carried out prior to their introduction, they may prove to be ( ineffective, colourful, effective ) or a ( pest, organism, crop ) themselves.

Question 8 of 12

1

is a process which is commonly used to extract and reproduce desirable characteristics in livestock and crops. This is useful as it can improve the organisms being farmed, often resulting in yield, better produce and more for the farmer. However, selective breeding also has risks. are responsible for these characteristics, and by reducing the of these alleles, the opportunities for varied breeding in the future are minimised. Furthermore, by making many organisms , the farmer is allowing their produce to become more liable to wipeout in or the introduction of a or disease. More would reduce the potential coverage of these kinds of changes.
