Study Notes

Ecological Concepts

  • Biosphere: The regions of Earth where living organisms exist.
  • Sustainable Environment: All living and non-living things on Earth and their interconnections.
  • Ecology: The study of how living and non-living things interact.
  • Abiotic Factors: Non-living parts of an ecosystem (e.g., temperature, water, CO2).
  • Biotic Factors: Living parts of an ecosystem (e.g., plants, animals, bacteria).
  • Biodiversity: Variety of organisms in an area; associated with healthy ecosystems.
  • Sustainability: The ability of populations to reproduce indefinitely.
  • Species: A group of similar organisms that can naturally interbreed.
  • Population: A group of the same species living in the same area.
  • Community: The populations of different species interacting in an area.
  • Stewardship: Taking care of something, like an environment.
  • Ecosystems: The relationships between organisms and their environment.
  • Biomes: Collections of ecosystems with the same dominant plant life.
  • Diverse Structure: Healthy ecosystems have various organisms, each with a specific role (niche).
  • Nutrient Cycles: Cycles that allow nutrients to be absorbed and reused by organisms in ecosystems.
  • Energy Flows: Energy originates from the sun and flows through food chains; energy is not recycled.
