Which of the following is not a characteristic of rapidly growing populations?

Long length of reproductive life

Cycads are gymnosperms that were diverse and abundant during the Mesozoic era. Extant species of cycads share many traits with those from the Mesozoic era. Cycads bear cones, are long-lived with slow growth rates, show late reproductive maturity, and have very few offspring. Based on this description, the cycads are

K-strategists with a Type I survivorship curve.

r-strategists with a Type III survivorship curve.

K-strategists with a Type III survivorship curve.

r-strategists with a Type II survivorship curve.

What is a generalist species?

Species with a broad range of tolerance

Species with a narrow range of tolerance

The K-selection reproductive strategy maximizes survival of offspring by producing

few offspring with high levels of parental care

many offspring with low levels of parental care

few offspring with low levels of parental care

many offspring with high levels of parental care

Which of the following best describes a density-independent factor that controls population size?

Occurrences of droughts and flooding

Competition for resources like food and water

Infectious disease transmission

Reduced availability of habitat

What is happening at the 'A' on the graph?

growth begins to slow down due to limited resources

the population overshoots above the carrying capacity

growth is speeding up due to an abundance of resources

show a decline after an increase

display populations that have reached carrying capacity

does not depend on the numbe rof resources

Which is true about a population's carrying capacity?

it depends on a limiting resource

it is usually used when studying ecosystems

it is controlled by density-independent factors

Which of these would NOT be true of a specialist species?

They often lose in competition for resources to generalists.

They are more likely to go extinct during changes to an ecosystem.

They often feed on a very specific diet.

When a specific population grows past the ecosystem's carrying capacity, what happens to the population?

Density Dependent limiting factors start to occur resulting in the population going back below carrying capacity.

Density Independent limiting factors start to occur resulting in the population going farther above carrying capacity.

The population will go extinct due to lack of resources

The population grows then finds a new carrying capacity

A lion and a cheetah attempt to occupy the same niche. The more aggressive lion survives; the cheetah does not.

Density-Independent: Competition

Density-Dependent: Predator-Prey

Density-Independent: Predator-Prey

Since lynx prey on hares, an increase in the hare population causes an increase in the lynx population.

Density-Dependent: Predator-Prey

Density-Independent: Competition

Density-Independent: Predator-Prey
