HELPP PLSSS :) American pikas are prey to long-tailed weasels. Which change in a limiting factor would increase the carrying capacity for long-tailed weasels in a talus field within an alpine tundra? A. increase in American pika population size B. decrease in American pika population size C. increase in the long-tailed weasel population size D. decrease in the long-tailed weasel population size

A. increase in American pika population size

Explanation:

Carrying capacity is the idea that relates to how much population can an environment sustain before collapsing. Here, the answer would be A. increase in American pika population size  because if you increase the food for weasals, naturally the population carrying capacity goes up because now the environment has food to feed the weasals which can contribute to increasing the carrying capacity (i.e. the environment can now handle larger population of weasel than initial condition)

the element that provides strength to the exoskeletons of clams and oysters is phosphorus.

this is so because calcium carbonate is the main component in the shells. calcium carbonate is strengthened by phosphorus.

explanation:

chert is a sedimentary rock composed of microcrystalline or cryptocrystalline silica. with this little bit of information, you can come to the conclusion that your answer is c.
