ES chapter 8

In which of the following pairs do both organisms belong to the same population?

• a rose and a carnation

• a zebra and a horse

• two residents of Madison County

• Two similar species of Monkeys

A population of some species is most likely to grow exponentially

• if the species is already very common in the area

• when the species moves into a new area of suitable habitat

• when it uses the same habitat as a similar species

• if the population size is already large

a population will most likely deplete the resourced of its environment if the population

• grows beyond carrying capacity

• must share resources with many other species

• moves frequently from one habitat to another

• has a low reproductive potential

the growth rate of a population of geese with probably increase within a year if

• more birds die than are hatched

• several females begin laying eggs at younger ages than their mothers did

• most females lay two eggs instead of three during a nesting season

• some birds get lost during migration

which of the following is an example of competition between species

• two species of insects feeding on the same rare plant

• a bobcat hunting a mouse

• a lichen, which is an alga and and a fungus living as a single organism

• a tick living on a dog

Which of the following statements about parasitism is true

• the presence of a parasite does not affect the host

• parasitism is a cooperative relationship between two species

• parasites always kill their hosts

• parasitism is similar to predation

ants and acacia trees have a mutualistic relationship because

• they are both adapted to a humid climate

• they benefit each other

• they are part of the same ecosystem

• the ants eat part of the acacia tree

Which of the following is an example of coevolution

• flower that can be pollinated by only one species of insect

• rabbits that invade a new habitat

• wolves that compete with each other for territory

• bacteria that suddenly mutate in an a lab

A tapeworm lives in the intestines of a cow. What relationship is this?

• symbiosis

• parasitism

• competition

• predation

what does the dashed line represent?

• Carrying Capacity

• exponential growth

• population density

• Growth rate
