In Stabilization Selection there is a decrease in the amount of variation. In the case of Stabilization Selection, selective pressures must select against two extremes of a particular trait. Two opposing selection pressures will combine to maintain a median height. Rather than resulting in extremely tall plants or extremely short plants, the majority of the plants in this population will be of medium height.

Answer: Global warming
Explanation:
Global warming can be defined as the phenomenon in which there is an increase in the global temperature of the world.
This is because there is an increase in the carbon dioxide concentration in the environment.
The increase in the overall carbon dioxide absorbs more heat which tends to increase the temperature of earth.

C-population
D-biome
All of the white-tail deer living in an ecosystem are considered as a population. Thus, the correct option is C.
A population is the complete set group of individuals, a nation or a group of people with some common characteristics. A population is the pool of individuals from which a statistical sample can be drawn for a study.
A population consist of individuals which can interbreed with each other and produce fertile offspring. Thus, can maintain their number in an ecosystem such as all the white-tail deer organisms living in an ecosystem make a population. Many different population form a community.
The characteristics of a population include population density, natality, mortality, population growth, age distribution, and population fluctuations.
Therefore, the correct option is C.

extinction would lead to the extinction of other forms of life. A keystone species helps to
support the ecosystem of which it is a part.
An example of what can happen when a keystone species is removed occurred when fur
hunters eliminated sea otters from some Pacific Ocean kelp beds. Otters eat sea urchins,
which eat kelp. With its major predator gone, sea urchin populations exploded and
consumed most of the kelp. Fish, snails, and other animals associated with the kelp beds
disappeared.
The grizzly bear is another example of a keystone species. Grizzlies transfer nutrients
from the ocean ecosystem to the forest ecosystem. The first stage of this transfer is
performed by salmon that swim up rivers, sometimes for hundreds of miles. Salmon are rich
in nitrogen, sulfur, carbon, and phosphorus. The bears capture the salmon and carry them
onto dry land, scattering nutrient-rich feces (wastes) and partially eaten salmon carcasses.
It has been estimated that the bears leave up to half of the salmon they harvest on the
forest floor.
Which sequence best represents the feeding relationships in a kelp ecosystem that has not been disturbed
by humans?
(1) sea urchins → kelp → fish (3) kelp → sea otters → sea urchins
(2) kelp → sea urchins → sea otters (4) sea urchins → snails → kelp
The correct sequence displaying the feeding relationships in an undisturbed kelp ecosystem is: kelp → sea urchins → sea otters. Kelp serves as a food source for sea urchins, which in turn are consumed by sea otters.
The sequence that best represents the feeding relationships in a kelp ecosystem that has not been disturbed by humans is (2) kelp → sea urchins → sea otters. In an undisturbed ecosystem, the kelp, being a producer, forms the base of the food chain. Secondly, the sea urchins, as primary consumers, feed directly on the kelp. And finally, the sea otters are secondary consumers that prey on the sea urchins, maintaining the balance in the ecosystem.
