what would be the major result of long-term use of the same pesticide ona fruit orchard?
a. reduced fruit production
b. increased fruit production
c. soil pollution
d. salization of soil
e. etiolation of leaves
is it d?
soil microflora and microfauna are often affected with long term use of the same pesticide.
i don't know what those are. Which answers would it apply to (a,b,c,d,or e?)
To determine the major result of long-term use of the same pesticide on a fruit orchard, we need to consider the potential impacts of pesticide use on the orchard ecosystem.
The given options are:
a. reduced fruit production
b. increased fruit production
c. soil pollution
d. salinization of soil
e. etiolation of leaves
To evaluate each option, we can analyze the potential long-term effects of pesticide use on a fruit orchard:
a. Reduced fruit production: Pesticides are chemicals designed to control pests, but if used excessively or for an extended period, they can harm beneficial insects like pollinators and natural pest predators. This can disrupt the natural balance and reduce fruit production. Therefore, option a is a possible major result of long-term pesticide use on a fruit orchard.
b. Increased fruit production: Pesticides are typically used to control pests and diseases that can damage crops. However, long-term pesticide use can lead to the development of pesticide-resistant pests, which can in turn increase the need for more potent pesticides. This can create a vicious cycle and eventually cause decreased fruit production. Therefore, option b is unlikely to be the major result of long-term pesticide use on a fruit orchard.
c. Soil pollution: Pesticides can leach into the soil and accumulate over time, leading to soil pollution. This can harm soil microorganisms, earthworms, and other beneficial organisms that play crucial roles in maintaining soil health and fertility. However, while soil pollution can be a significant concern, it may not be the primary result of long-term pesticide use on a fruit orchard. Therefore, option c is less likely to be the major result.
d. Salinization of soil: Salinization refers to the accumulation of salts in the soil, which can adversely affect plant growth. Pesticides themselves are not directly responsible for salinization, as their primary function is pest control. Salinization typically occurs due to excessive irrigation with water high in dissolved salts or improper drainage practices. Therefore, option d is not the major result of long-term pesticide use on a fruit orchard.
e. Etiolation of leaves: Etiolation is the abnormal elongation and pale coloration of leaves due to the lack of exposure to sufficient light. Pesticides, when used appropriately, should not directly cause etiolation of leaves. Therefore, option e is not the major result of long-term pesticide use on a fruit orchard.
Considering the analysis above, the correct answer would be option a. Reduced fruit production is a possible major result of long-term use of the same pesticide on a fruit orchard.
