Answer:
I think the answer is B. I think energy decreases as it moves up tropic levels when it is lost as the organisms from one level consume the organisms in the other.
Explanation:
It can't be A because animals do travel from one ecosystem to another. It's migration. It's not C because air can be used by organisms as once as the air moves out of their ecosystem because air is everywhere and the organisms need air to breathe and to live. D is definitely incorrect because matter can't be created or destroyed. Remember that an ecosystem is the organisms physical environment. I hope this answers your question.
The correct answer is a. Complex
A complex or undefined medium is rich in nutrients, which contain water-soluble extracts of plant or animal tissue, a sugar, (often glucose is added to serve as the main carbon and energy source). The combination of extracts and sugar creates a medium which is rich in minerals and organic nutrients, but the exact composition is unknown.
The type of solution formed is hypertonic.
<h3>What are hypertonic solutions?</h3>
Hypertonic solutions are solutions with higher dissolved solutes as compared to the sap of the cells suspended in them.
Epsom salt is made up largely of magnesium sulfate. Thus, a solution formed by dissolving Epsom salt is water will have more magnesium in it than the cells of the part of the body soaked in it.
Hence, such a solution is hypertonic.
