5. In a tundra ecosystem, the carrying capacity for arctic hares is about 400 individuals. Which of these events is MOST likely to reduce the carrying capacity for arctic hares in the ecosystem by at least 25 percent?
(A) a severe storm that kills about 100 adult and young arctic hares
(B) a 25 percent decrease in the populations of foxes, wolves, or other predators of arctic hares
(C) the arrival in the ecosystem of a species that competes with the arctic hare for its food
(D) a temporary increase in the arctic hare population to more than 425 individuals
(E) a mutation that introduces a new fur color to the arctic hare population
A temporary increase in the arctic hare population to more than 425
individuals.
Hares are among the primary consumers as they are herbivores while foxes
are secondary consumers which feeds on the hares.Foxes will hunt the
hares for food which will drastically reduce their population
Increasing their population by 425 individuals with the hares having a
population of 400 will surely decrease their carrying capacity in the tundra
ecosystem.

rita has two small containers one holding liquid and one holding a gas rita transfers the substances to two larger containers compare the behaviors in the atoms in the liquid and in the gas once they are moved to larger containers
Answer:The behavior of the both liquid and gas will be different in some aspect and same in the other, lets see how:
Explanation:
As we have studies that liquids donot have a specific shape but do have a specific volume. So when the liquid will be transferred from small to large container, it will adapt the shape of new container but its volume will stay same as it was in old container.
On the other hand, about gases, we know that they donot have specific shapes and the volume is also not definite and depends on the shape of container. Therefore, the gas atoms will freely move in the container and the volume will be changes in large container.
