Answer:
Natural selection can be described as a phenomenon in which individuals of a population which are better adapted to survive in an environment are favored by nature as compared to the individuals of the population which lack better characteristics to survive in the environment.
Through natural selection, evolution occurs and the allelic frequency changes over a period of time. The process of evolution as well as change in the allelic frequencies does not occur just by a single individual, rather it is a collective effort which takes a lot of time. Hence, we say that natural selection changes the population and not a single individual.
Answer:
D) The fungicide will reduce the stability of the ecosystem because nutrients in the soil will be less likely to be recycled, directly impacting plant nutrition and growth.
Explanation:
Fungicide are primarily applied to an area to kill off fungi species in that place.
Fungi are very important groups of organisms. They are natural "recyclers".
In a food chain or web they can be classified as decomposers.
Decomposers are organisms that takes feeds on dead and decaying organic matter.
The produce useful materials and releases nutrients from life back into nature.
Killing them off by applying fungicides is a damaging act to their sustenance.
Without decomposers such as fungi, the ecosystem becomes less stable and soil nutrients will not be properly recycled.
