Why are there no rooted plants in limnetic zone of a lake or pond

Because of the depth that makes it difficult to establish rooted plants.

Explanation:

The limnetic zone is the region that goes as far as the light reaches. Their communities are plankton (bacteria, algae and zooplankton) and necton (fish). Unlike the coastal zone where photosynthesis is performed by plants, in this region it is performed by algae. The limnetic zone in lakes and lagoons is very deep and although this region receives sunlight, which would facilitate the existence of plants, the depth hinders the establishment of roots of these plants. For this reason, there are no plants rooted in the limnetic zone of a lake or pond.

a neutral ph of 7 and normal organism temperature is needed for a certain enzyme to be effective.  

what would happen to the enzyme if the ph and/or temperature fluctuate greatly from the norm?  

a.the enzyme’s hydrogen bonds will break.  

b.the activation energy will increase.  

c.more product will be formed.

d.the ideal temperature and ph for the enzyme function will decrease.

explanation:

carbon can form so many different compounds not just with oxygen
