In aquatic biomes,
A)as water temperature increases,dissolved oxygen content does too.
B)organisms must spend their whole life cycle in either a saltwater or freshwater biome.
C)chlorophyll concentration is an index of net primary productivity.
D)anadromous and catadromous fish can tolerate waters with virtually no dissolved oxygen.

Question

Quizplus · Accepted Answer

Chlorophyll concentration is an index of net primary productivity in aquatic biomes, as it indicates the abundance of photosynthetic organisms and their ability to convert light energy into organic matter. Option A is incorrect, as high water temperature can lead to decreased dissolved oxygen content due to thermal stratification and reduced mixing of water layers. Option B is also incorrect, as some organisms such as salmon are able to migrate between saltwater and freshwater habitats for different life stages. Option D is incorrect, as anadromous and catadromous fish species require adequate dissolved oxygen levels for survival, especially during their migrations.
