← Nature & AnimalsWhich outcome occurs when Antarctic krill consumes dimethylsulfoniopropionate (DMSP)?
A)Assimilation increases, boosting dimethylsulfide (DMS)
B)Denitrification accelerates, losing fixed nitrogen✓
C)Osmoregulation fails, leading to cell lysis
D)Methanogenesis elevates, reducing fixed nitrogen
💡 Explanation
Denitrification enhances if Antarctic Krill consumes DMSP because gut microbiome decomposition generates nitrite via microbial nitrate reductase, accelerating loss of nitrogen through denitrification, therefore releasing N2 gas back into the atmosphere rather than retaining usable fixed nitrate.
