What to Focus On

  • Ecology studies interactions between organisms and their environment.
  • Term coined by Ernst Haeckel in 1866.
  • Derived from Greek words: 'oikos' (household) and 'logos' (study).
  • Hierarchy: Genes → Cells → Organ → Organism → Population → Community → Ecosystem.
  • Population: Same species in one place at one time.
  • Species: Group that can interbreed and produce fertile offspring.
  • Environment = Abiotic + Biotic components.
  • Abiotic: Physical and chemical factors like light, temperature, water, minerals.
  • Biotic: Living organisms — producers, consumers, decomposers.

Common Mistakes to Avoid
