The genetic variation in the population will decrease or stay the same

Explanation:

In an ecosystem , if environmental conditions forced a population of these organisms to use only asexual reproduction, the genetic variation in the population will decrease or stay the same.

What is an ecosystem?

Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Which word describes the scientific study of weather and the atmosphere?

meteorology
environmental science
geomorphology
atmospherology

Answers

Answer:

I think the answer should be meteorology

Meteorology is the word that describes the scientific study of weather and the atmosphere.

What is weather?

Weather is the state of the atmosphere, describing for example the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloudy. On Earth, most weather phenomena occur in the lowest layer of the planet's atmosphere, the troposphere, just below the stratosphere. Weather refers to day-to-day temperature, precipitation, and other atmospheric conditions, whereas climate is the term for the averaging of atmospheric conditions over longer periods of time. When used without qualification, "weather" is generally understood to mean the weather of Earth.

Weather is driven by air pressure, temperature, and moisture differences between one place and another. These differences can occur due to the Sun's angle at any particular spot, which varies with latitude. The strong temperature contrast between polar and tropical air gives rise to the largest scale atmospheric circulations.

2 - When we plant a tree we get many benefits one of them is we have more fresh air which will better circulate the air flow in more populated areas of major attraction

3 - A longer life span, removing all the junk from our streets and sewers can actually increase our life span.
