Modeling Ecosystems Grasslands Michelle Escudero

Organisms in my ecosystem Plants Ryegrass elodea Animals Crickets Fish Earthworms

Food Chain Decomposers Primary Producers Herbivores Primary Consumers Omnivores Secondary Consumers Carnivores Tertiary Consumers

Similarities & Differences  Ponds  Life  Representation  Sustain Life  Big & Wide  Many species  Multiple pond/ big pond  Small/ condensed  only four species  small, restricted pond Real Ecosystem Bottle Ecosystem

Energy Sources Plants Animals Sun and Oxygen  Allows the plant to photosynthesize  Allows the plant to make its own food Elodea/ Ryegrass  Gives the animals food to eat Other plant  Supplies oxygen

Organisms Using Energy Elodea | Ryegrass | Fish | Crickets To Stay Alive!!

Cellular Processes Carbon Dioxide, Water, Light energy Glucose Oxygen Photosynthesis Break down food Use oxygen Cellular Respiration

GROWING I would know if my ecosystem is growing if i see it continuously thrive and grow.
