Which change in a limiting factor would increase the carrying capacity for american pikas in a talus field within an alpine tundra?

a) increase in number of rock fragments

b)decrease in number of rock fragments

c)increase in american pika population size

d)decrease in american pika population size

its actualy sience but no subject for dat

B) decrease in number of rock fragments

Explanation:

Carrying capacity is the maximum size of the population of a species that an ecosystem can handle based on the availability of resources.

A limited factor is the factor that can be an abiotic or biotic agent is likely to affect the life of the living being.

American pikas are the small rodent-like mammals. These animals are short and stout. They have big, round ears and do not have tails. They have a brown and black coloration which helps them to hide behind the rocks and camouflage the predators.

Here, the decreased in rock fragments is a limiting factor which will increase the carrying capacity of American pikas. Due to lack of rock fragments, the American pikas will not be able to hide from predators and they will die. The size of the population will become by the supportive carrying capacity.

answer; /// i believe that the correct answer is; ///a combination of the birth and death

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
