Question

part 4: carrying capacity
carrying capacity is the maximum number of organisms that an environment can support over time without running out of resources. this limit is determined by limiting factors. when a population grows too large, resources become scarce, leading to increased competition, starvation, or other challenges. as a result, the population decreases until it reaches a balance with what the environment can provide. populations tend to stay near their carrying capacity.
to figure out the carrying capacity of an environment, you need to observe how a population grows over time and identify when it stops increasing and stabilizes.

1. how do limiting factors influence carrying capacity?
2. create a graph using the population data.
3. about what population size does the graph level off, showing the carrying capacity?

Explanation:

1. Limiting factors (e.g., resource scarcity) set the upper - limit (carrying capacity) of an environment. When a population nears this limit, these factors cause population size adjustments (like decreases) to maintain balance.
2. To create the graph:

• Label the x - axis as "Time (Years)" and mark values from 0 to 12.
• Label the y - axis as "Population Size" and mark values from 0 to 1000.
• Plot points for each (Year, Population) pair (e.g., (0,0), (1,100), (2,200), etc.).
• Connect the points with a smooth curve.

1. Looking at the data, after year 7 (population = 800), the population fluctuates around 800 (e.g., 800 at year 7, 820 at year 8, 800 at year 9, 805 at year 10, 810 at year 11, 800 at year 12).

Answer:

1. Limiting factors determine the carrying capacity by setting the maximum number of organisms an environment can support. When a population approaches this limit, limiting factors (such as resource scarcity) cause the population to adjust (e.g., decrease) to a level that the environment can sustain.
2. (Graph should be drawn as per the steps above)
3. The graph levels off at a population size of about 800, showing the carrying capacity.
