Module Test: Population Ecology

Imagine Olivia, Evelyn, and Sophia are on a thrilling adventure in Canada. They come across a group of grizzly bears. Which of the following would not be used to describe the population of these majestic creatures?

• geographic distribution

• demographic history

• population range

• population density

Imagine Oliver, Scarlett, and Hannah are observing a group of rabbits in a field. They notice that the rabbit population seems to be increasing very quickly. Which characteristic of exponential population growth might explain this observation?

• The lag phase follows rapid growth.

• Initial population growth is rapid.

• Growth rate is inversely proportional to population size.

• Resources are consumed exponentially during all phases.

Which organism follows an r-strategy for reproduction?

• zebra

• human

• robin

• mayfly

Anika, Lily, and Daniel are having a debate about the current human population growth. Anika thinks it's increasing growth and decreasing rate of growth, Lily thinks it's decreasing growth and increasing rate of growth, Daniel thinks it's increasing growth and rate of growth. Who do you think is correct?

• Anika: increasing growth and decreasing rate of growth

• Lily: decreasing growth and increasing rate of growth

• Daniel: increasing growth and rate of growth

• None of them

Imagine Nora, Aria, and Noah are on a fun-filled adventure in a deciduous forest. They come across 78 Norway maple trees in every hectare they explore. This scenario is a perfect example of what?

• population density

• population range

• dispersion

Imagine this, Grace, Sophia, and Evelyn spotted twenty gray squirrels scurrying away from their forest home into a new ecosystem. This scenario is an example of what?

• emigration

• immigration

Imagine this scenario: William, Arjun, and Emma are having a heated debate about the factors contributing to the current human population growth. Can you help them settle the argument?

• They agree on improved healthcare, medical advancements, increased agricultural productivity, better sanitation and hygiene, access to education and family planning, and reduced infant mortality rates

• They think it's due to improved healthcare, medical advancements, decreased agricultural productivity, poor sanitation and hygiene, limited access to education and family planning

• They believe it's because of decreased healthcare, lack of medical advancements, low agricultural productivity, limited access to education and family planning, high infant mortality rates

• They suggest it's due to decreased agricultural productivity, lack of access to healthcare, high infant mortality rates, limited education and family planning, poor sanitation and hygiene

How does the introduction of twenty gray squirrels into a new ecosystem impact the existing species?

• Increased biodiversity and improved ecosystem stability.

• Enhanced cooperation and mutual benefit among species.

• Competition for resources and potential decrease in population size or displacement of native species.

• No impact on the existing species due to natural adaptation.

Which organism follows an r-strategy for reproduction and what are its characteristics?

• The organism that follows an r-strategy for reproduction is a species that produces a large number of offspring with little parental care. Its characteristics include early maturity, short lifespan, small body size, high reproductive rate, and low survival rate of offspring.

• The organism that follows an r-strategy for reproduction is a species that produces a large number of offspring with high parental care.

• The organism that follows an r-strategy for reproduction is a species that produces a moderate number of offspring with moderate parental care.

• The organism that follows an r-strategy for reproduction is a species that produces a small number of offspring with high parental care.

Imagine Kai, Liam, and Benjamin are playing a video game where they have to manage a virtual population. They notice that their population is growing rapidly over time, and the growth rate seems to be proportional to the current population size. What kind of population growth are they experiencing and what could be the implications?

• They are experiencing exponential population growth, which is characterized by a rapid increase in population size over time, with the growth rate being proportional to the current population size. Its implications could include resource depletion, environmental degradation, and increased competition for resources in their game.

• They are experiencing exponential population growth, which is characterized by a decrease in population size over time, with the growth rate being proportional to the current population size.

• They are experiencing exponential population growth, which is characterized by a constant population size over time, with the growth rate being proportional to the current population size.

• They are experiencing exponential population growth, which is characterized by a slow increase in population size over time, with the growth rate being proportional to the current population size.
