📚 Quick Study Guide

  • 🌍 Ecosystem Definition: An ecosystem is a community of living organisms (plants, animals, and microbes) interacting with each other and their physical environment.
  • 🌱 Key Components: Biotic (living) and abiotic (non-living) factors. Biotic includes plants, animals, and microorganisms. Abiotic includes water, sunlight, soil, and air.
  • 🐟 Aquarium Ecosystem: A closed aquatic environment containing fish, plants, and microorganisms. It demonstrates nutrient cycling and interdependence.
  • 🌿 Terrarium Ecosystem: A closed terrestrial environment containing plants, soil, and sometimes small invertebrates. It demonstrates water cycling and plant growth.
  • 🍄 Decomposition Column: A layered system demonstrating decomposition, nutrient cycling, and the role of decomposers like fungi and bacteria.
  • ☀️ Energy Flow: Energy enters ecosystems primarily through sunlight, which is then converted into chemical energy by plants through photosynthesis ($6CO_2 + 6H_2O \rightarrow C_6H_{12}O_6 + 6O_2$).
  • 🔄 Nutrient Cycling: Nutrients like nitrogen and carbon are recycled within the ecosystem through processes like decomposition and the nitrogen cycle.
