Explanation:

Positive feedbakc occurs when something happens that triggers B, this B then causes the first thing that originally happened to happen again, and it is a vicious circle that harms the system into unestability.

adoni [48]

Answer:

Disruptive selection

Explanation:

According to the infographic that is attached below showing different the three main types of selection that occurs as a result of natural selection taking its course on any population, we can draw our conclusion regarding the information given to us from the question.

From the question above, it states that the finches studied by Darwin are majorly finches with either small beak or large beak which are all adapted to suit the type of food available for the finches in the islands. Whereas, finches with intermediate beaks are favored against.

According to the infographic, disruptive selection can be said to have taken place as extreme traits are favored against intermediate traits on the islands.

Why would a ecosystem that had a high species diversity be more productive and effective?
nydimaria [60]

Answer:

the higher the diversity, the higher the populations of all the

photosynthetic organisms

Explanation:

Diversity in plant allows random mating also known as panmixia. It allows plant have equal chances of being mated too by any among them creating variations in the population. It leads to less fixed gene, reduce genetic drift leading to an increases population as some lethal gene may be lost due to recombination of gene among individual plant.

Where there is no diversity some gene becomes fixed leading to perpetuation of some traits that may be harmful in a population but diversity allows for the generation of new gene and allele frequency within a population.
