What limits carrying capacity?
Limited resources such as food, water, habitat, and sunlight.
What happens to resources during overshoot?
Resources are depleted, leading to environmental damage and increased competition.
What causes a population crash?
Lack of food, famine, disease, and intense competition.
Describe the relationship between resource availability and carrying capacity.
Limited resources = lower carrying capacity; abundant resources = higher carrying capacity.
How do overshoot and die-offs regulate population size?
They act as negative feedback loops, rebalancing the population after it exceeds resource availability.
Why is understanding population dynamics important?
Crucial for managing ecosystems and preventing long-term environmental damage.
What type of growth is represented by a J-curve?
Exponential growth, occurring when resources are unlimited.
What type of growth is represented by an S-curve?
Logistic growth, showing population leveling off near carrying capacity.
What determines carrying capacity?
Availability of resources like food, water, habitat, and sunlight.
Why is carrying capacity important?
It helps understand the limits of population growth and manage ecosystems.
What are the consequences of overshoot?
Resource depletion, environmental damage, and increased competition.
What causes a population die-off?
Lack of food, famine, disease, and intense competition after an overshoot.
What limits population growth?
Limited resources (food, water, habitat), competition, predation, disease.
What is the relationship between resource availability and carrying capacity?
Limited resources = lower carrying capacity; Abundant resources = higher carrying capacity.
How do feedback loops relate to population dynamics?
Overshoot and die-offs are negative feedback loops that regulate population size.
Why is understanding population dynamics important for ecosystem health?
It's crucial for managing ecosystems and preventing long-term damage.
What is the effect of exceeding carrying capacity?
Resource depletion, environmental damage, increased competition, and potentially a population crash.
What causes a population overshoot?
A period of rapid growth due to abundant resources, leading to a population size that exceeds the environment's carrying capacity.
What are the consequences of a population die-off?
A significant reduction in population size and potential long-term impacts on the ecosystem.
What is the effect of limited resources on population size?
Limited resources restrict population growth and lower the carrying capacity.
