Below are sample questions representative of the exercises included on this worksheet and related 7.36 Resource Availability and Carrying Capacity skill assessments:

Problem 1Difficulty: Mastery

In a reservoir, the population of fish is limited by TWO resources: oxygen (mg/L) and plankton (mg/L). Data show the habitat can provide enough food for about 80 individuals, but it has space/shelter for only about 36 individuals.

Which graph best supports a conclusion about the carrying capacity based on these resource limits?

AA graph where the population levels off near 80 individuals (the larger limit) even though one resource cannot support that many.

BA graph where the fish population grows and then levels off near 36 individuals (the smaller of the two limits).

CA graph where the population stays at 0 the whole time, even though resources could support a population.

DA graph where the population keeps increasing without slowing down, as if resources never become limiting.

Solution & Explanation:When more than one resource can limit a population, carrying capacity is set by the most limiting resource (the smaller capacity). Because one resource supports only about 36 individuals, the best graph levels off near 36.

Problem 2Difficulty: Mastery

Two student groups investigated geese in a park and measured grass (kg/week) and pond area (m²).,,Science Group 1 recorded population size over time only.,,Science Group 2 recorded BOTH resource amount and population size over time.,,Science

,,Science "Which graph would provide the STRONGEST evidence for carrying capacity caused by limited resources?,A. A graph that shows population leveling off near 90 but does not include any resource data. | B. A pie chart of the types of resources in the habitat. | C. A graph that shows both the resource amount decreasing as population grows and then the population leveling off near 90 while the resource stays low. | D. A graph that shows only the resource amount changing

Solution & Explanation:answer choices

Problem 3Difficulty: Mastery

A wildlife team studied seal pups in a beach. The limiting resource was safe resting spots (m²) and milk supply (L/day). Before adding resources, the population leveled off around 50. After week 6, the team added more of the limiting resource, enough to support about 70 individuals.

Which graph best supports the conclusion that carrying capacity increased after week 6?

AA graph where the population levels near 70 before week 6 and then drops to 50 after week 6.

BA graph where the population is perfectly flat the entire time, even after the added resource.

CA graph where the population keeps increasing without any leveling before or after week 6.

DA graph where the population levels near 50 before week 6 and then rises and levels near 70 after week 6.

Solution & Explanation:If the limiting resource increases, carrying capacity can increase. The graph should show a first plateau near 50 and a second, higher plateau near 70 after the resource is added.
