Question

which of the following best describes what happened to the collared lemming population from 1994 to 1995?
choose 1 answer:
a the population remained stable.
b the population decreased.
c the population increased.
what is the best explanation for this pattern?
choose 1 answer:
a the collared lemming population was experiencing relatively low predation pressure.
b the collared lemming population was experiencing relatively high predation pressure.

Explanation:

Since no data about the collared - lemming population from 1994 - 1995 is given, we assume based on general knowledge of population dynamics. If predation pressure is low, populations tend to increase. If it is high, they tend to decrease. For the first question, without more information, we can't be sure, but if we assume normal conditions and no major negative factors, populations often increase over a short - term period. For the second question, low predation pressure would allow the population to grow.

Answer:

C. The population increased
A. The collared lemming population was experiencing relatively low predation pressure.
