Answer: a. dead organisms from the marine food web.
c. liberation through ATP hydrolysis in living organisms.
Upwelling is a wind driven motion of lower bottom nutrient rich and warmer water on the surface of the water body. This wind driven motion facilitates the movement of nutrients available for growth of primary producers like phytoplanktons growing on the surface of water body. The dead organisms from the marine food web get decomposed and the organic matter obtain after decomposition is a rich source of phosphorous. This phosphorous gets transferred to the upper layers of the water body by upwelling. In aquatic organisms ATP hydrolysis occurs which is a catabolic process that uses water to split the bonds present in the ATP molecule and hence, releases energy for functions performed by them along with a release in phosphate atom. This phosphate gets mixed with the water. Therefore, PO32 come from dead organisms from the marine food web and liberation through ATP hydrolysis in living organisms that circulates due to upwelling.
Answer:
Okay let me break this down, so you have a pure red and pure white feathered chicken meaning that the chickens have homologous alleles. Overtime, as you breed the two you may get multicolored chickens but they can carry the recessive white feathers alleles (FWFW) meaning that they can still produce all white chickens and they can continuously do that over generations. Selective breeding may be negative because you may not get the desired result, you could breed for the wrong traits, other characteristics are lost and the resulting population is very similar. Less genetic variation can cause the chickens to not be resistant to problems like diseases and could fall ill.
Explanation:
Because if the new species is better at doing whatever the original species does, the original species can die because they are outcompeted by the new species, and because the new species is better, they can cause a further decline of for example the food supply that they're outcompeting the original species for. This can cause problems in the entire food web/ecosystem
Answer: B. Commensalism
Explanation: Commensalism is an association between two organisms in which one benefits and the other derives neither benefit nor harm. So, since the remora benefits and the shark is really not harmed or benefitted, B is the best answer.
Answer:
A reliable source is one that provides a thorough, well-reasoned theory, argument, discussion, etc. based on strong evidence. Scholarly, peer-reviewed articles or books -written by researchers for students and researchers. Original research, extensive bibliography.
