What to Focus On

  • Ecology studies organism-environment and organism-organism interactions
  • Ernst Haeckel coined the term ecology in 1866
  • Ramdeo Misra is the Father of Ecology in India

  • Four major abiotic factors: temperature, water, light, and soil
  • Eurythermal vs stenothermal organisms based on temperature tolerance
  • Poikilothermal vs homoiothermal organisms based on temperature regulation

  • Four responses to stress: regulate, conform, migrate, suspend
  • Regulators vs conformers in maintaining homeostasis
  • Hibernation (winter sleep) and aestivation (summer sleep)

Common Mistakes to Avoid

Exponential growth curve continues indefinitely in nature

Carrying capacity (K) is always constant for a given habitat

Competition is always harmful to both species involved
