How might a wide variety of plants affect an ecosystem's sustainability? A. The more types of plants there are, the more nutrients will be in the soil, increasing the ecosystem's likelihood of survival.

B. If disease strikes, only some types of plants will be affected, increasing the ecosystem's likelihood of survival.

C. The more types of plants there are, the more competition for resources will take place, decreasing the ecosystem's likelihood of survival.

D. If disease strikes, the plants will all be affected and likely die, decreasing the ecosystem's likelihood of survival.​

A.

Explanation:

Why does biodiversity contribute to a habitat's sustainability? The more plants and animals in a habitat, the greater the biomass, which is how habitats store energy. The greater the number of species, the more competition there is for food between predators, which sustains their populations.

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".

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.
