Where in a lake is the benthic zone?

a. above the limnetic zone

b. on the surface near the middle

c. along the bottom

d. in the shallow water near the shore

C. Along the bottom

Explanation:

The benthic zone is an lowermost ecological region of the aquatic water body like ocean, river, lakes and pond. It includes the sediment surface and the layers of water above it. It receives very little sunlight penetration of only 1%. As a result of this, the zone remains dark and animals show bio-luminescence in order to search and capture prey.

On the basis of the above explanation, the benthic zone in a lake can be found C.along the bottom.

nonconformity

answer: the unkar group shows angular unconformity because the layers are turned at angle.

unconformity

answer: specifically the angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled. an angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled.

disconformity

answer: the disconformities aremarked irregular lines between the sedimentaryrocks layers.
