Cross over? i have no idea lol
Biological magnification, or biomagnification, occurs when pollutants taken up by organisms at the base of the food chain reach high concentrations in the bodies of animals at the top of the food chain. Effects of biomagnification vary widely depending on the pollutant, organism and ecosystem in question.
Considering the following statements;
A. It can exist without a constant source of energy input
B. It must contain consumers but can exist without producers.
C. It involves interactions between biotic and abiotic factors.
D. It can exist on land, but it cannot exist in lakes, rivers, or oceans.
The correct statement is C. that an ecosystem involves interactions between biotic and abiotic factors.
Biotic factors are the living things in an ecosytem, they include plants, animals, bacteria, fungi and others. Abiotic factors on the other hand, are the non-living factors in an ecosystem, they include water and air, sunlight, the amount precipitation in an ecosystem is also an example of abiotic factor. The two types of factors are crucial for an ecosystem to exist and thrive.
The water from the 5% glucose solution will flow into the 10% one, as water molecules will flow from a region of high water potential (dilute solution) to a region of lower water potential (concentrated solution) by osmosis.
Osmosis only occurs when a differntially membrane exist, and its only about the net movement of water particles.
Therfore the result would be the water volume in the 10% glucose would rise, and the solute in the original 10% one would be less concentrated, while originally in the 5% one would be more concentrated.
