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.
See sample questions for grade 9
A forest can support up to 200 deer. If the deer population increases to 250, what is the carrying capacity of the forest?
A lake has a carrying capacity of 1,000 fish. If the fish population is currently 800, what can you infer about the availability of resources?
A population of 1,200 birds lives on an island with a carrying capacity of 1,000. What is likely to happen to the bird population?
A population of 400 animals is living in an area with a carrying capacity of 600. If the birth rate is higher than the death rate, what will likely happen to the population?
A population of insects in a field increases rapidly, then levels off. What type of growth is this?
A population of rabbits grows rapidly until it reaches 500, then stabilizes. What is the likely carrying capacity for rabbits in this environment?
Describe how a drought might affect the carrying capacity of a grassland for herbivores.
Describe one way human activities can increase the carrying capacity of an environment for a particular species.
Describe one way in which invasive species can affect the carrying capacity of native species.
Describe what might happen to a population if a new predator is introduced into its environment.
Explain how limiting factors affect the carrying capacity of an ecosystem.
Explain the difference between density-dependent and density-independent limiting factors, giving one example of each.
Explain what happens to competition among individuals as a population approaches its carrying capacity.
Explain why carrying capacity is important for the long-term survival of a species.
If a population exceeds its carrying capacity, what is likely to happen to the population size over time?
If a population is consistently below its carrying capacity, what might this indicate about the environment?
What is the definition of carrying capacity in ecology?
A grassland ecosystem supports a population of 1,000 gazelles. Due to a prolonged drought, the water supply is reduced by half. Predict and explain the likely impact on the carrying capacity for gazelles in this ecosystem.
A population of 300 wolves lives in a forest. Over several years, the population fluctuates between 280 and 320, but never grows beyond 320 or falls below 280. Explain what this pattern suggests about the carrying capacity of the forest and the factors that might cause these fluctuations.
A population of 500 fish in a pond is limited by the amount of dissolved oxygen. If the oxygen level drops by 20% due to pollution, and the carrying capacity is directly proportional to oxygen availability, what is the new carrying capacity for the fish?
