  1. Ecology Review

  2. Which of the following is NOT a biotic factor in a prairie dog ecosystem? A. Grass and other plants that the prairie dog eats B. Hawks, ferrets and other animals that hunt the prairie dog C. The soil that provides the prairie dog with a home D. Worms, fungi and bacteria that live in the soil

  3. What is the correct order of the levels of organization of living things? A. organism – population – community -- ecosystem B. ecosystem – population – community -- habitat C. organism – population – biotic factor - ecosystem D. organism – succession – community -- ecosystem

  4. A prairie dog, a hawk and a badger are all members of the same A. niche B. community C. species D. population

  5. Which of the following is NOT an example of limiting factors for populations? A. time B. weather C. space D. food

  6. Wolves are predators of moose on Isle Royale. If the moose population rises, what do you predict will happen to the wolf population? A. The wolf population will increase until the moose population begins to decline due to too many predators B. The wolf population will decrease because they will have to compete with a larger moose population C. The wolf population will stay the same because they are in a mutualistic relationship with the moose D. The wolf will go extinct due to overhunting

  7. Although three different bird species all live in the same tree in an area, competition between the birds rarely occurs. The most likely explanation for this lack of competition is that these birds A. occupy different niches B. have a limited supply of food C. eat the same food D. live in the same part of the tree

  8. The amount of energy transferred from one level to the next in a food web is A. 5% B. 10% C. 50% D. 90%

  9. The process of evaporation, condensation and precipitation make up the A. food web B. carbon and oxygen cycles C. water cycle D. nitrogen cycle

  10. “Free” nitrogen is changed into a usable form of nitrogen in the process called A. primary succession B. nitrogen fixation C. condensation D. legumes

  11. The type of biome that exists in an area is determined by its A. people B. climate conditions C. food webs D. invasive species

  12. Matching Population ecology habitat carrying capacity energy pyramid symbiosis ecosystem invasive species Limiting factors extinction biodiversity The study of how living things interact with each other and with their environment ecology

  13. Matching Population ecology habitat carrying capacity energy pyramid symbiosis ecosystem invasive species Limiting factors extinction biodiversity All the members of one species in a particular area population

  14. Matching Population ecology habitat carrying capacity energy pyramid symbiosis ecosystem invasive species Limiting factors extinction biodiversity The largest population that an area can support carrying capacity

  15. Matching Population ecology habitat carrying capacity energy pyramid symbiosis ecosystem invasive species Limiting factors extinction biodiversity An environment that provides the things the organism needs to live, grow and reproduce habitat

  16. Matching Population ecology habitat carrying capacity energy pyramid symbiosis ecosystem invasive species Limiting factors extinction biodiversity A diagram that shows the amount of energy that moves from one feeding level to another in a food web Energy pyramid

  17. Matching Population ecology habitat carrying capacity energy pyramid symbiosis ecosystem invasive species Limiting factors extinction biodiversity A species that is not native to an ecosystem Invasive species

  18. Matching Population ecology habitat carrying capacity energy pyramid symbiosis ecosystem invasive species Limiting factors extinction biodiversity A close relationship between two species that benefits at least one of the species symbiosis

  19. Matching Population ecology habitat carrying capacity energy pyramid symbiosis ecosystem invasive species Limiting factors extinction biodiversity A community of organisms that live in a particular area along with their non-living surroundings ecosystem

  20. Matching Population ecology habitat carrying capacity energy pyramid symbiosis ecosystem invasive species Limiting factors extinction biodiversity The number of different species in a an area biodiversity

  21. Matching Population ecology habitat carrying capacity energy pyramid symbiosis ecosystem invasive species extinction biodiversity The disappearance of all members of a species from Earth extinction

  22. Interactions Predation competition mutualism commensalism parasitism A lion hunts, attacks, kills and eats a zebra predation

  23. Interactions Predation competition mutualism commensalism parasitism The seeds of purple loosestrife, an invasive species, migrate to an island and take the space of native plants competition

  24. Interactions Predation competition mutualism commensalism parasitism Wrasses, a reef fish, clean the mouth and gills of the moray eel to gain its meal mutualism

  25. Interactions Predation competition mutualism commensalism parasitism Barnacles live on a whale to have a place to live, but they do not take anything from the whale and the whale is not harmed commensalism

  26. Interactions Predation competition mutualism commensalism parasitism In the rainforest, the strangle fig tree grows around another tree as it absorbs the tree’s nutrients and eventually kills the tree parasitism

  27. A rocky island appears as ocean waters recede. What type of species would probably appear first on the bare rocks? Pioneer species, like mosses and lichens, would be the first to appear

  28. A rocky island appears as ocean waters recede. What type of succession does this demonstrate? Why? Primary succession is demonstrated because the area is starting with bare rock

  29. An old warehouse was torn down. Small weeds and grasses grew on the abandoned land. Over the few years, bushes and tree seedlings began to grow. What will eventually happen to this land over a long period of time? A forest will eventually grow.

  30. An old warehouse was torn down. Small weeds and grasses grew on the abandoned land. Over the few years, bushes and tree seedlings began to grow. What type of succession does this demonstrate? Why? Secondary succession is demonstrated because soil is present at the beginning.

  31. A food web is overlapping food chains in an ecosystem Define a food web

  32. Describe a food chain in this food web.

  33. Producers can make their own food through photosynthesis Why do all food chains start with a producer?

  34. Mushrooms are decomposers. What is the role of mushrooms in this web?

  35. The populations of squirrel, shrew, snake and bird would increase. What would happen if all the hawks died?
