Interdependency Unit 1 Study Guide Pgs. D10-D13, D16-D17, D18-D19, D20-22 Be sure you know what the following words mean. There will be a matching section on the test. I’ve given you a SHORT explanation. Vocabulary: ecosystem – living and non living being together abiotic – Never living or alive factor in an ecosystem biotic- Living or once living factors in an ecosystem producers – green plants that make their own food photosynthesis –process where green plants make their own food consumers – organisms that eat other organisms carnivores – consumers that eat only meat herbivore – consumers that eat only plants omnivore – consumers that eat both plants and animals decomposer – break down dead organisms and waste from organisms food chain - one path transfer of energy food web – overlapping food chains catastrophic event – Event causing loss or widespread destruction symbiosis – species that form long-term close relationships with other species commensalism –one species benefits and the other is unaffected. mutualism – all species benefit from the relationship parasitism - one species benefits and the other is harmed Topics •Put the following factors in an ecosystem under the proper heading: grass, flowers, mold, sunlight, cricket, water, rocks, mushroom, soil, temperature, oak tree, fox, Biotic Abiotic •Fill in the blanks with the correct words: Photosynthesis is the ____________________ where ____________plants make their own _______________. They use ____________________, which is a chemical, along with _________________, _________________, and ___________________. Chlorophyll gives them a _____________ color. Once everything is mixed together, the green plant produces ________________ and _________________which is given off as a waste product. •Label if the organism is a producer, consumer or decomposer. Then explain why it falls into that category.

Human, lion, squirrel, giraffe, rabbit, black rat snake, raccoon, black bear, mouse, box turtle, spider, Herbivore Carnivore Omnivore • Give examples of how ecosystems change from natural causes and from human interaction. •Nature: •Human Interaction: •Name 3 kinds of catastrophic events that nature can produce: 1. 2. 3. •Name 3 ways that the ecosystems can change because of these events. Symbiotic Relationships Name two different relationships that are examples of mutualism. 1. 2. Name two different relationships that are examples of commensalism. 1. 2. Name two different relationships that are examples of parasitism. 1. 2.
