. Mass extinction
. Global warming
. Gene dominance
. Natural selection

Answers

Answer 1

Answer:

Global warming

Explanation:

Weather can be defined as the atmospheric conditions of a particular area over a short period of time.

The elements of weather include precipitation, wind, temperature, atmospheric pressure, relative humidity, cloud, and wind speed.

Climate refers to the change in the atmospheric conditions and manifestation of weather in a particular area over a long period of time usually 30 years.

Pollution can be defined as the physical degradation or contamination of the environment through an emission of harmful, poisonous and toxic chemical substances.

Greenhouse gases can be defined as gases that trap heat within the Earth's atmosphere. Thus, an increase in global temperature is largely caused due to an increase in the amount of greenhouse gases in Earth's atmosphere.

Some examples of greenhouse gases present in the atmosphere are methane, water vapor, carbon dioxide etc.

Global warming can be defined as a gradual increase in the average temperature of Earth's surface, atmosphere and ocean due to artificially induced actions or human activities through pollution such as burning of fossil fuels, CFCs, carbon dioxide, etc.

In this scenario, the range shift provides evidence for the theory of global warming.

Answers

Answer:

A star's brightness also depends on its proximity to us. The more distant an object is, the dimmer it appears. Therefore, if two stars have the same level of brightness, but one is farther away, the closer star will appear brighter than the more distant star - even though they are equally bright!

The diagram shows part of the food web in Yellowstone
National Park, Humans began removing gray wolves from

How is removing the gray wolf from this food web most likely to affect other species in the food web ?

A. The grass population will stay the same

B. The elk population will increase

C. The aspen population will increase

D. The coyote population will decrease

Answers

If the gray wolf is removed from the Food web, the population of elk will increase. Thus, the correct answer is option B.

What is a food web?

A food web is a diagram that shows what is eaten by what in an ecological community and how food chains naturally connect to one another. Consumer-resource system is another term for the food web.

A food web's connections show the various feeding routes, such as how heterotrophs consume the organic matter produced by autotrophs and other heterotrophs to receive organic matter themselves. The different feeding strategies that connect an ecosystem into a single system of trade are depicted in a simplified way by the food web.

In the in Yellowstone National Park when humans began removing gray wolves from the park in the early 1900s, the population of elk started increasing as elk is eaten by the gray wolves.

Therefore, the elk population will increase when the gray wolf is removed from this food web.

Which of the following does NOT occur as ecological succession progresses?
A.Soils that are rich in nutrients become deeper.
B.Larger plants and animals inhabit the area.
C.Biodiversity decreases.
D.Sustainability increases.

Answers

Answer:

uhh C?

I think

Biodiversity decreases does NOT occur as ecological succession progresses. Hence, option C is correct.

What is ecological succession?

The process by which a region's species and habitat mix evolves over time is called ecological succession. These communities gradually replace one another until a "climax community" is attained, such as a mature forest, or until a disruption, such as a fire, happens. A key idea in ecology is ecological succession.

For instance, when a tree falls in an established forest, sunlight may once more be able to penetrate the forest floor, allowing new growth to start. In this instance, fresh, smaller plants would be the first in the succession. Communities are ever-evolving and expanding.

ecological succession is the process by which a biological community's structure changes over time. Primary and secondary succession have been identified as two distinct forms.

Thus, option C is correct.
