- Limiting factors are resources or conditions (like space, food, oxygen, water, temperature, and precipitation) that regulate the number of organisms an ecosystem can support.
- Carrying capacity is the maximum population size an ecosystem can sustainably support, determined by the availability of limiting factors.
- Population size typically grows until it reaches the carrying capacity, after which it stabilizes and fluctuates around that level.
- Changes in abiotic (e.g., water, oxygen) or biotic (e.g., food) factors, natural disasters, or human activities can alter the carrying capacity.
- If a population exceeds its carrying capacity for too long, resources may be depleted, making the ecosystem unsuitable and potentially causing the population to die off.
Parent Tip: Review the logic above to help your child master the concept of limiting factors worksheet.
