  3. Plants & Our Environment for 200 Deforestation and loss of plants in an ecosystem, reduces this process, which provides energy to an ecosystem.

  4. Plants & Our Environment for 200 What is ‘photosynthesis’?

  5. Plants & Our Environmentfor 400 Of the three major roles in the food web, plants serve as this.

  6. Plants & Our Environment for 400 What are ‘producers’(or ‘autotrophs’)?

  7. Plants & Our Environment for 600 Making new paper from old paperthrough recycling helps preserve forestsby reducing the number of these thatneed to be cut for wood to make paper.

  8. Plants & Our Environment for 600 What are trees?

  9. Plants & Our Environment for 800 The three major reactants and two major products from photosynthesis.

  10. Plants & Our Environment for 800 What are water, carbon dioxide, and light as the reactants and oxygenand carbohydrates (or sugars or glucose) as the products?

  11. Plants & Our Environment for 1000 This is the name of the process by which moisture is carried through plants fromroots to small pores on the undersideof leaves, changes to vapor andis released to the atmosphere.

  12. Plants & Our Environment for 1000 What is ‘transpiration’?

  13. Animals & Our Environment for 200 In an energy pyramid, less energy is available to higher orders of these, which include animals.

  14. Animals & Our Environment for 200 What are consumers?

  15. Animals & Our Environment for 400 This will happen to the population of an invasive species that is introduced into an ecosystem where it has no known predators.

  16. Animals & Our Environmentfor 400 What is ‘increase’ or ‘take over’?

  17. Animals & Our Environment for 600 There are five main needs of animals including air (or ‘gases”). Name the other four which are all affected whenhuman beings encroachupon on animal habitats.

  18. Animals & Our Environment for 600 What are food, water, shelterand open space?

  19. Animals & Our Environment for 800 If a pesticide killed the grasshoppers, this animal in the food web below would be MOST affected next.

  20. Animals & Our Environment for 800 What are ‘frogs’?

  21. Animals & Our Environment for 1000 Restate the following: “Humans are causing a decline in blue crabs in the Chesapeake Bay ” using “phyla-speak” (a phylum is the taxonomic rank below “kingdom” and above “class”) by filling in the blanks in this statement: “A ________ is causing a decline in _____________ in the Chesapeake Bay.” (Remember, humans have a backbone and blue crabsare crustaceans; they have a hard exoskeleton.)

  22. Animals & Our Environment for 1000 What is “Chordates are causing a decline in arthropods in the Chesapeake Bay”?

  23. Cycles in Nature for 200 The cycle in nature that humans directly affect by burning fossilfuels and releasing carbondioxide into the atmosphere. .

  24. Cycles in Nature for 200 What is the ‘carbon cycle’?

  25. Cycles in Nature for 400 Chemical fertilizers contain a large amount of ammonium and nitrates. As a result, humans are directlyaffecting this cycle in naturewith the use of chemical fertilizers.

  26. Cycles in Nature for 400 What is the nitrogen cycle?

  27. Cycles in Nature for 600 Global warming is meltingpolar ice caps and glaciers, which directly affectsthis cycle in nature.

  28. Cycles in Nature for 600 What is the ‘Hydrologic Cycle’or the ‘Water Cycle’?

  29. Cycles in Nature for 800 Producers (plants) take CO2 from the atmosphere and convert it to this usableform in the energy pyramid (the primaryusable form of energy that plantsproduce during photosynthesis).

  30. Cycles in Nature for 800 What are ‘sugars’ (or ‘glucose’ or ‘carbohydrates’)?

  31. Cycles in Nature for 1000 What it is called when twoorganisms of different specieslive and work together.

  32. Cycles in Nature for 1000 What is ‘symbiosis’ (or in this case, a specific type of symbiosis called ‘mutualism’)?

  33. Life Around Us for 200 A coral reef is an example of one of these – a community of organismsand the abiotic elementsin their surroundings.

  34. Life Around Us for 200 What is an ‘ecosystem’?

  35. Life Around Us for 400 Loss of habitat increases this among populations within an ecosystem(it results when two or moreorganisms are seekingthe same resource).

  36. Life Around Us for 400 What is ‘competition’?

  37. Life Around Us for 600 Introducing an invasive speciesinto an ecosystem can affect the relationship in a food web among decomposers, consumers,and these.

  38. Life Around Us for 600 What are producers?

  39. Life Around Us for 800 Agricultural run-off of fertilizers into water ecosystems can cause this (it isthe generation of large ‘blooms’ of algaewhich can in turn disrupt thenormal functioning of the ecosystem).

  40. Life Around Us for 800 What is ‘eutrophication’?

  41. Life Around Us for 1000 By burning fossil fuels, humansadd to the heat-trapping gasesin the atmospherewhich are called this.

  42. Life Around Us for 1000 What are greenhouse gases?

  43. Grab Bag for 200 According to the figure, this category of animals (birds, rodents or amphibians) has the largest percentage of species in the ‘Critically Endangered’ and ‘Endangered or Vulnerable’ categories combined.

  44. Grab Bag for 200 What are amphibians(or Amphibia)?

  45. Grab Bag for 400 Due primarily to humans’ effecton our ecosystems, expertsestimate that this will happento 27,000 species every year.

  46. Grab Bag for 400 What is go extinct?

  47. Grab Bag for 600 This term applies to an organism’sphysical location and, most importantly,functional role (much like anoccupation—what the organismspecifically does) within an ecosystem.

  48. Grab Bag for 600 What is a ‘niche’?

  49. Grab Bag for 800 This biome is home to the largestterrestrial biodiversity. It isbeing destroyed in Latin Americato make way for cattleranching and farming.

  50. Grab Bag for 800 What are forests or tropical forests?
