1. Ecology definition

Key Concepts & Definitions

  • Ecology: the scientific study of interactions between organisms and their environments.
  • Abiotic environment: non-living chemical and physical factors such as light, temperature, water, and nutrients.
  • Biotic environment: living components like plants, animals, bacteria, and viruses.

Essential Points

  • Ecology focuses on how organisms interact with both living and non-living parts of their surroundings.
  • The abiotic environment includes factors like climate, water, minerals, and sunlight, which are non-living.
  • The biotic environment comprises all living components, including other organisms and microorganisms.

Key Takeaway

Understanding ecology begins with grasping the fundamental distinction between living and non-living components and their interactions.

2. Abiotic and biotic factors

Key Concepts & Definitions

  • Abiotic factors are non-living elements like climate, water, minerals, and sunlight that influence ecosystems.
  • Biotic factors are living components including other plants, animals, and microorganisms that interact within an ecosystem.
