In aquatic ecosystems with high concentrations of dissolved nutrients, increases in the decomposer population ultimately decrease the amount of dissolved oxygen in the water. This change most likely
results in
A- increases in photosynthetic bacteria in aquatic ecosystems.
B - increases in the biodiversity of aquatic ecosystems.
C -decreases in the carrying capacity for primary consumers in aquatic ecosystems.
D - decreases in competition between organisms in aquatic ecosystems.

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.

the most common type of reef is the fringing reef. this type of reef grows seaward directly from the shore. they form borders along the shoreline and surrounding islands.
