Limiting Factors in an Ecosystem

Limiting Factors in Ecosystems

The video explains the concept of limiting factors in ecosystems, which are abiotic or biotic factors that restrict the number or reproduction of organisms.

Key Scientific Concepts

• Limiting factors: Any factor (abiotic or biotic) that limits organism population size or reproduction.

• Examples in a fishbowl ecosystem: Size of the bowl, amount of water, temperature.

Types of Limiting Factors

• Dependent limiting factors: Depend on the number of organisms (e.g., food availability).

• Independent limiting factors: Do not depend on the number of organisms (e.g., rainfall).

• Density-dependent limiting factors: Specifically depend on population size, including:

  • Competition
  • Predation
  • Parasitism
  • Disease

Abiotic Limiting Factors

Abiotic factors are non-living environmental factors that can limit populations:

• Sunlight
• Climate
• Temperature
• Water
• Space
• Soil chemistry
• Fire
• Natural disasters

Biotic Limiting Factors

Biotic factors are living components affecting populations:

• Number of plants
• Number of animals
• Amount of competition
• Number of decomposers
• Number of parasites
• Disease-causing agents
