Understanding Carrying Capacity and Limiting Factors

What is the term used to describe the number of individuals of a species in a specific area?

• Carrying capacity

• Population density

• Limiting factor

• Population size

Which of the following is NOT a requirement for trees to survive?

• Sunlight

• Fresh air

• Nutrients from the soil

• Predators

What happens when a population reaches its carrying capacity?

• The population size decreases rapidly

• The population size becomes zero

• The population size stabilizes

• The population size continues to grow

Which of the following is a density-dependent limiting factor?

• Wildfire

• Food availability

• Drought

• Pollution

How does disease act as a density-dependent limiting factor?

• It is not influenced by population density

• It spreads faster in denser populations

• It only affects plant populations

• It affects all populations equally

Which of the following is an example of a density-independent limiting factor?

• Territory availability

• Mate availability

• Predation

• Hurricane

What is the effect of a heat wave on an ecosystem?

• It only affects large populations

• It increases the carrying capacity

• It impacts the ecosystem regardless of population size

• It has no effect on the ecosystem

What type of graph represents exponential growth?

• S curve

• Linear curve

• Bell curve

• J curve

In a healthy ecosystem, what does the population size typically do?

• Fluctuates wildly

• Increases indefinitely

• Decreases steadily

• Stays around the carrying capacity

How can humans ensure that plant and animal populations remain healthy?

• By altering the natural environment

• By leaving nature undisturbed

• By increasing the number of predators

• By introducing new species
