Bottle Biology With Energy of Ecosystems


  • Design an ecosystem that is self contained, Observe and understand the interaction of biotic and abiotic factors, Understand nutrient cycling and energy flow

Essential Question

  • Can the ecosystem be self sustaining and maintain life of all original organisms within it?


  • If designed correctly, it will be self sustaining.


  • Aquatic Animals, Terrestrial Animals, Plants, Water, Wicking String, Clear Packing Tape, 2 2 Liter Bottles, Box Cutters, Stove, Probes




  • Set your bottle were it can get sunlight and record changes over the next few days.



  • With the right trophic levels you can balance out the ecosystem so that the living organisms are sustainable. The plants and the soil in the bottle release water vapor, recycling water. The vapor is then collected onto the walls of the vessel and trickles down to the soil.
My bottle included primary producers (flowers, algae and water plant ), primary consumers (a fish and ant)


  • Producers: Organisms that produce their own food, such as plants.
  • Consumers: Organisms that consume energy from other organisms.
  • Trophic Levels: Where it stands on the food chain.
  • Decomposers: Organisms that feed off of waste.
  • Detritivores: Consumers such as bacteria, protists, fungi, insects, worms, and isopod crustaceans.
  • Tertiary Consumer: Carnivores that feed off of other carnivores.
  • Herbivores: Organisms that eat only plants
  • Rule of 10: Only a fraction of the energy available at one trophic level is transferred to the next tropic level
  • Autotrophs: An organism that manufactures its own food from inorganic substances, such as carbon dioxide and ammonia. Most autotrophs, such as green plants, certain algae, and photosynthetic bacteria, use light for energy.
  • Heterotrophs: An organism that cannot manufacture its own food and instead obtains its food and energy by taking in organic substances, usually plant or animal matter. All animals, protozoans, fungi, and most bacteria are heterotrophs. Compare autotroph.
  • Photosynthesis: A process that producers use to make their own food. It involves carbon dioxide, glucose, (a type of sugar), water, oxygen, and sunlight. After the process, oxygen is released into the air and the glucose released is a source of energy for the producer. Light energy is converted into chemical energy in this process.
