How does a decrease/decline in a top predator impact biodiversity in an ecosystem?

vivado [14]

Answer:

Results in biodiversity loss due to the proliferated growth of prey that feeds on smaller species

Please find the explanation below

Explanation:

In an ecosystem, organisms feed on one another to obtain energy. In this process organisms called CONSUMERS kill and feed on one another in a process called PREDATION. Top predators are those consumers that are found at the peak of the food chain.

A reduction in the number of top predators/tertiary consumers in an ecosystem means that the secondary consumers they feed on (prey) will grow and reproduce beyond control, hence, causing them to pose serious threat to the population of smaller species below them in the food chain.

Therefore, a decrease/decline in a top predator will impact biodiversity by causing it's loss, as organisms in lower level of the food chain will drastically diminish.

Based on your prior knowledge, make a claim about the factors that cause inherited genetic variations within populations. Also m

solniwko [45]

Answer AND Explanation:

FACTORS THAT CAUSE GENETIC VARIATIONS

Crossing over. At the chiasmata during prophase I of meiosis, breakage may occur and exchange of genetic information may take place. New gene combinations which result in variations.
Independent assortment. The arrangement of homologous chromosomes at the equator of the spindle during metaphase of the first meiotic division is random. These homologous chromosomes segregate into different daughter cells which contain different genetic combinations which brings about variation
Fertilisation permits parental genes to be brought together in different combinations. This is the cause of variations in members of the same family.
Mutation is the spontaneous change in the genetic makeup of an organism. These changes may be inherited by the offspring therefore beginning variation.

Crude oil is ________. a. composed of less than ten different hydrocarbon molecules b. usable in its raw form c. formed in a wid

kolbaska11 [484]

Crude oil is refined to separate the chemicals used for gasoline, lubricants, plastics, and other products.

In a distillation tower, the crude oil is separated by boiling point after being heated by a furnace.
The material is then transformed into finished goods like fuels like gasoline and diesel, as well as specialty items like asphalt and solvents, by using heat, pressure, or a catalyst.
Ethane, liquid petroleum gas (LPG), and naphtha are the three main petrochemical feedstocks generated from crude oil.
These are mostly employed in the creation of synthetic fibers, plastic polymers, and other petrochemical intermediates.
With increased global income, demand for these products will only continue to rise.

Among reported cases through May 17, 90% were unvaccinated or their vaccination status was unknown. Fifty-five (6%) cases were acquired outside of the U.S. (international importations) and 825 (94%) were acquired in the U.S. Most cases (94%) were related to outbreaks and 75% were related to outbreaks in New York City and New York State.
