<u>Answer:</u>
The fluctuations that are present in abiotic cycles have an impact on living organisms and on ecosystems as a whole because any system that is present in a community requires the support of abiotic system
The materials that are present in an environment require the involvement of both biotic and abiotic system. The biotic community comprises of the living organisms that coexists in an ecosystem whereas abiotic factors are the non-living factors that influences the living of organisms in an ecosystem.
The most characteristic feature of clastic sedimentary rocks is "stratification".
<u>Answer:</u> Option A
<u>Explanation:</u>
"Stratification" is an essential characteristic of the sedimentary rocks take place in an igneous rock produced at the surface of the Earth naturally due to volcanic fragmental deposits and flows of lava. It defines the pattern in which sediment layers are layered over each other and may occur on a scale of hundreds of meters, even down to sub-millimeter.
It also results from variations in texture or composition during deposition. Delays in deposition may also permit for variations to the older deposits before coverage given by new sediments. This mechanism in sedimentary rocks change in both, the degree of prominence and in structure details.
Answer:
True
Explanation:
An independent variable is the variable you think is the cause,while a dependent variable is the effect. you manipulate the independent variable and measure the outcome in the dependent variable.
Answer:
If a whole specie of organisms has to survive, they should must possess the ability to reproduce and adopt to environmental conditions in better way.
For example: If a disaster occurs or a condition of unfavorable weather occurs, the specie will survive even if only few members remain alive. Because those members will reproduce and regrow the community.
The reason is this that reproduction is not important for the survival of one organism, like organism will still survive even if he do not reproduce, but if a whole specie has to survive and continue, reproduction is most important trait.
