C. Excision of a population from the ecosystem
D. Removal of many populations of an organism

A

Explanation:Human activities and natural disasters such as deforestation, tornadoes, floods, pollution, etc. The biodiversity of an ecosystem contributes to the sustainability of that ecosystem. Higher/more biodiversity = more sustainable. Lower/less biodiversity = less sustainable.

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.
