Population and Resources

A resource population is:

• a population that is avoided by organisms

• a population that is traded between organisms

• a population that is eaten by organisms from another population

• a population that is never eaten because it doesn't taste good.

What do you think would happen to the lion population if the hyena population increases in size? Assume that the populations were stable before this change.

• The lion population would increase.

• The lion population would not change.

• The lion population would decrease.

• The hyena population would increase.

In Australia, both opossums and foxes eat rats. The sizes of the populations have been stable for the last 12 years, but recently the size of the opossum population increased. What will likely happen to the fox population?

• increase. An increase in the size of any population leads to an increase in the sizes of all other populations in an ecosystem.

• decrease. Fewer energy storage molecules will be available to the fox population from the smaller rat population, so the fox population will reproduce less. This will lead to fewer births than deaths in the fox population.

• decrease. The larger opossum population will leave fewer energy storage molecules for all other populations in the ecosystem, so the fox population will reproduce less. This will lead to fewer births than deaths in the fox population.

• stay the same. Opossums and foxes do not eat each other, so the number of births and deaths in the fox population will stay the same.

When a populations is known to be STABLE, it:

• there are more deaths

• stays mostly the same, over time

• there are more births

• horses live there

Carrying Capacity is...

• The average of the birth rate and death rate in a population

• A practice where you use only what you need, and there is more resources for future generations

• The maximum amount a population can reach and support the population

How has the human population changed over time?

• There has been no population change.

• It has increased steadily over the last 500 years

• It stayed the same throughout most of history and increased drastically in the last 50 years

Why does the rise in human population matter? What impact does it have?

• The rise of the human population matters because with more people there will be a demand for more resources. With more of a demand, it could deplete those resources.

• The rise of the human population matters because with more people there will be a demand for less resources. With less of a demand, it could allow for us to have too many resources.

• There is no impact of human population on our Earth, environment, etc

What is the carrying capacity of an environment?

• The maximum population size that an environment can sustain indefinitely

• The minimum population size needed for a species to survive

• The average population size in a given area

• The total number of species in an ecosystem

Which of the following is a renewable resource?

• Coal

• Natural Gas

• Solar Energy

• Uranium

How does overpopulation affect natural resources?

• It leads to the conservation of resources

• It increases the availability of resources

• It leads to the depletion of resources

• It has no effect on resources
