Question

what is the impact of pests on food crops worldwide? they increase the yield of food crops by 50%. they have no significant impact. they destroy about 1/3 of all food crops. they enhance crop production.

Explanation:

Pests typically harm food crops (e.g., by feeding on plants, spreading diseases), reducing yields. Scientific data shows pests destroy around 1/3 of global food crops. The other options (increase yield, no impact, enhance production) contradict pest biology/agricultural science, as pests negatively affect crops, not improve them.

Answer:

C. They destroy about 1/3 of all food crops.
