Answer:
Probably insects developed resistance to the pesticide.
Explanation:
The term resistance refers to an inheritable change in the population sensitivity, reflected through the consecutive failure of the chemical effects, correctly used in order to reach a certain effect on the insect population.
Insecticides might produce a genetic modification in the insects, leading them to survive under the effects of the chemical. Insects evolve with the capability of tolerating the poison dose that normally is used to destroy a normal population of plagues.
In the exposed example, the first time that the farmer sprayed the pesticide, the insect population decrease sharply. This means that the chemical affected them severely. The surviving individuals probably suffered a genetic modification and survived. They probably passed this modification to the following generations, which expressed it, and developed resistance to the pesticide.
The carbon cycle is the movement of carbon from cellular respiration and human interference to the atmosphere. Human interference adds an excessive amount of carbon to the atmosphere, resulting in an imbalance. This imbalance means there is less oxygen available to organisms who need it, such as humans and animals. Burning of fossil fuels and deforestation are some contributors into the imbalance of carbon and oxygen in the atmosphere. Hope this helps! :)
D. All of the above.
Explanation - An organism has encountered reproduction, getting energy and staying healthy as their challenge. Limiting factor plays an important role in this. When the amount of limiting factor is sufficient then different organisms try to grow and reproduce but here the competition between the species arise.
Different species need to compete with each other for their food, growth and reproduction. The species that is unable to sustain itself in the amount of limiting factor available tends to get extinct.
B. the rate will decrease. plants need carbon dioxide
