Which of these is an abiotic factor of an aquarium ecosystem? a. algae growing on the glass
b. gravel on the bottom of the aquarium
c. plants growing from the gravel
d. fish swimming in the water

Answers

Answer 1
Answer: b. gravel on the bottom of the aquarium

An ecosystem involves both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which interacts as a system. More importantly, the living things are very dependent on the abiotic community since it cannot survive by itself. Every animal, plant and human needs the primary physiological needs of water, food and shelter provided by the abiotic system.   

Biotic factors:
Plants
Microorganisms
Macroorganisms
Answer 2
Answer:

I am pretty sure that the answer is B! I just took the Test and it makes sense because abiotic means not living feature and gravel isn't a living feature! Hope this helps!

Acid rain does which of the following?A. increases nutrients in soil
B. enhances leaf growth in plants
C. neutralizes lakes, streams, and oceans
D. damages statues, buildings, and other structures

Answers

The best answer is option D.Acid rain is simply rainfall that has been rendered acidic due to water vapor reacting with nitrogen oxide ad sulphur dioxide very high up in the atmosphere.Acid rain is not only a threat to the ecosystem and environment, but also seriously damages buildings and sculptures.Marble and limestone are especially vulnerable to acid rain. This is because the two building or construction materials contain calcite which is easily dissolved by acid.Concrete surfaces and paint finishes are also seriously damaged by acid rain.

While the co2 levels and the temperature increase, the water levels decrease. what effect will this have on the light reactions? and the calvin cycle?

Answers

which plant would stand to gain more from increasing carbon dioxide levels?

in C3 plants, the binding of O2 rather than CO2 by rubisco leads to photorespiration, answering the efficiency of photosynthesis, but C4 plants overcome this problem by concentrating CO2 in the bundle sheath cells at the cost of ATP so rising carbon dioxide levels should benefit C3 plants by lowering the amount of photorespiration that occurs. at the same time, rising temperatures have the opposite effect, increasing photorespiration. but C4 plants are largely unaffected by increasing CO2 levels or temperature
