7 th Grade Science Study List for the Chapter 22 TEST 22-1 Know the definition of the following words: o Habitat o Population o Community o Ecosystem o Biotic factor o Abiotic factor o Ecology Know what a habitat provides to organisms. What is the difference between a community and ecosystem? Be able to recognize the different descriptions. Be able to name 3 biotic factors. Know the biggies (5) abiotic factors Be able to recognize a description of a population compared to a community ** LOOK AT THESE RESOURCES FOR YOUR REVIEW of 22-1: Your Practice Quiz Your 22-1 Class Notes (in your Notebook) The 22-1 Directed Reading
22-2 Know the definitions of the following words: o Population density o Immigration o Emigration o Birth rate o Death rate o Limiting factor o Carrying capacity Be able to figure out a population density given the number of organisms and the area in which they live (remember the equation) What are the two major ways that a population changes size? Know how the birth rate and death rate together affect the population size. o Be able to write a population statement with symbols. What are the four ways that scientists use to determine the size of a population? Be able to recognize an example of these four ways. Know what a habitat provides for organisms. ** LOOK AT THESE RESOURCES FOR YOUR REVIEW of 22-2: Your 22-2 Class Notes (in your Notebook) The 22-2 Directed Reading The 22-2 Review WS (with graph)
22-3 Know the definitions of the following words: o Niche o Adaptation o Competition o Predation o Predator o Prey o Symbiosis o Mutualism o Commensalism o Parasitism o Parasite o Host How can being specialized (having special adaptations or feeding in a certain way/place) help to limit competition between species? What are some predator adaptations? Prey adaptations? How do predators help keep the balance of an ecosystem? (Hint: how does predation affect prey species populations?) Be able to recognize the three different kinds of symbiosis in an example. Describe one of each here. Be able to recognize an example of each of the MAIN THREE types of interactions between organisms. Describe one of each here. ** LOOK AT THESE RESOURCES FOR YOUR REVIEW of 22-2: Your 22-3 Class Notes (in your Notebook) The 22-3 Directed Reading The 22-3 Review WS (with graph)
EXAMPLE TEST QUESTIONS A bluegill fish, a leopard frog, and a dragonfly nymph are all members of the same a. Ecosystem b. Community c. Species d. Population (Answer B. Community all living things interacting; not any non-living things) Which of the following is NOT an example of a population? a. The white-tailed deer at Crab Orchard Wildlife Refuge b. The people in a city c. The rainbow trout in a stream d. The birds in a forest (Answer: D the birds might not be all one species; see definition of population) When a snake squeezes a mouse in order to eat it, the mouse is the a. Predator b. Prey c. Host d. parasite (Answer: B the animal eaten is called prey. ) The prothonotary warbler and the cliff swallow both hunt for small insects. How is the interaction between them best described? a. Predator-Prey b. Mutualism c. Competition d. Coevolution (Answer: C even if you don t know what the organisms are you see that they are competing for the resource of food) Counting animal tracks to estimate the size of a population is the method called a. direct observation b. indirect observation c. sampling d. mark and recapture (Answer: B this is looking at evidence of animals, so is indirect) Matching: a. parasitism b. mutualism c. commensalism A squirrel building a nest in an oak tree. (Answer: C the squirrel benefits and the tree is not helped or harmed-neutral; +/0)
