It depends on what the big fish and the small fish eat
There are fewer phytoplanktons in the mesopelagic zone because of LOWER LIGHT LEVELS. It is the area of the ocean that is just below the epipelagic zone. This area of the ocean extends from a depth of 200 to 1000 meters.
Answer:
C. Both A and B describe errors in the statement.
Explanation:
In fossilization i.e formation of fossils, two terms are used as follows: permineralization and petrification.
- Permineralization is a process whereby the pore spaces of an organism's remains are filled with mineral matter that precipitates from lake and ocean solutions.
- On the contrary, petrifaction or petrification is the process whereby a once-living tissue (matter) are REPLACED by minerals, hence, preserving the organism's structure by turning it into a stone (petros).
According to this question, the student mixed up their definitions by giving the definition of permineralization instead, however, options A and B have described the errors associated with the statement.
The correct answer is option (B) It supports the anti-drilling argument.
Deepwater drilling refers to the process of drilling holes in the deep sea, below the seabeds for the purpose of mining petroleum compounds. Deepwater horizon blowout was an explosion causing a huge oil offshore oilspill in the Gulf of Mexico, making it the largest accidental marine oil spill disaster in the world. It has a numerous negative effects on the marine life.
The toxic oil and its compounds released into the water during the deepwater horizon blowout has contaminated the water and affected the marine life including the phytoplanktons, zooplanktons, invertebrates, fishes and other mammals of the sea. Highly toxic chemical components such as benzene and polycyclic aromatic compounds have even caused DNA damage and mutations in the marine life. Apart from their mortality, it has also been responsible for reduced growth, diseases, impaired reproduction in the sea fauna. Thus, ingestion of such contaminated seafood grown in contaminated water can be held responsible for the rise in cancer rates. Thereby supporting the anti-drilling arguement.
