📚 Quick Study Guide

  • 🌱Organism: A single living thing (e.g., a deer).
  • 👨‍👩‍👧‍👦Population: A group of the same type of organism living in the same area (e.g., a herd of deer).
  • 🏘️Community: All the different populations living together in an area (e.g., deer, squirrels, trees, and birds).
  • 🏞️Ecosystem: The community plus the non-living parts of their environment (e.g., sunlight, water, soil).
  • 🌍Biome: A large area characterized by its climate, plant, and animal life (e.g., desert, rainforest).
  • 🌐Biosphere: All the ecosystems on Earth combined. It's the portion of Earth where life exists.
  • ☀️Energy Flow: Energy moves through these levels, typically starting with the sun. Producers (plants) capture sunlight and convert it into energy. Consumers (animals) eat the producers or other consumers to get energy.
