Chemosynthetic bacteria Chemosynthesis-the process where organisms make energy using chemicals (instead of sunlight).

Chemosynthetic bacteria Primary Consumer Tubeworm Primary Consumer Primary Producer Secondary Consumer Tertiary Consumer Zoarcid fish Chemosynthetic bacteria Vent octopus Pompeii worm ***Arrows always point to the mouths of the predator***

Relevant vocabulary Autotroph- organisms that can produce their own food (e.g. plants) Heterotroph- have to eat other organisms as their food source Producer- another word for autotroph Consumer- another word for heterotroph Primary consumer- organisms that eat plants (e.g. grasshopper) Secondary consumer- organisms that eat primary consumers (e.g. a mouse) Tertiary consumer- organisms that eat secondary consumers (e.g. an owl)

More relevant vocabulary Herbivore- an animal that only eats plants Carnivore- an animal that eats other animals Omnivore- an animal that eats plants and animals Detritivore- an organism that gets energy from eating dead things (detritus). Decomposer- breaks down decaying organisms

Notes for lesson delivery Chemosynthetic bacteria use sulfides to create energy. Riftia tubeworms that have no mouth or eyes, but get their energy from the bacteria that live inside of them. Pompeii worms are the most heat-tolerate animals on earth, they are able to withstand temperatures up to 176 degrees F. The gray on it is actually bacteria. Zoarcid fish are about two feet long and they move slowly and lethargically. Vent octopi are activity carnivores that eat crabs, shrimp, mussels and much more Discovered vents in 1977 Video showing some of the cool things that live at vents: http://www.nationalgeographic.org/media/deep-sea-hydrothermal-vents/
