Carrying Capacity
Biology ⇒ Ecology and Environment
Carrying Capacity starts at 9 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Carrying Capacity.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.

A forest can support a maximum of 200 deer. If the deer population increases to 250, what will likely happen to the population in the next few years?
A population of 1000 birds lives on an island with a carrying capacity of 1200. If the birth rate is higher than the death rate, what will happen to the population?
A population of 1500 insects is living in a habitat with a carrying capacity of 1200. What is likely to happen to the population?
A population of 400 animals has a birth rate of 0.05 and a death rate of 0.03 per year. If the carrying capacity is 500, what is the net population growth rate per year?
A population of 800 animals is living in an area with a carrying capacity of 1000. If the population grows by 10% per year, what will the population be after one year?
A population of fish in a lake is limited by oxygen levels. If pollution reduces oxygen, what happens to the carrying capacity?
A population of rabbits in a meadow grows rapidly until food becomes scarce. What type of limiting factor is food in this scenario?
Calculate the population growth rate if r = 0.2, N = 500, and K = 1000 using the logistic growth equation.
Describe how invasive species can affect the carrying capacity of native species in an ecosystem.
Describe the relationship between carrying capacity and sustainability.
Describe two ways in which carrying capacity can be increased in an ecosystem.
Explain how technological advances have affected the carrying capacity for humans.
Explain how the concept of carrying capacity relates to logistic population growth.
Explain the difference between density-dependent and density-independent factors in relation to carrying capacity.
Explain why carrying capacity is considered a dynamic, rather than a static, value.
Explain why populations rarely remain exactly at carrying capacity.
If a population exceeds its carrying capacity, what is the most likely outcome?
If a population is below its carrying capacity, what is likely to happen to its size?
List three abiotic factors that can influence the carrying capacity of an ecosystem.
The logistic growth equation is dN/dt = rN(1 - N/K). What does 'K' represent in this equation?
