What are PRODUCERS? ORGANISMS THAT ARE ABLE TO CREATE THEIR OWN FOOD THROUGH
PHOTOSYNTHESIS. EX. PLANTS
What are AUTOTROPHS? PLANTS, AUTOMATICALLY MAKE THEIR OWN FOOD THROUGH
PHOTOSYNTHESIS
What are CONSUMERS? RECEIVE ENERGY BY CONSUMING OTHER ORGANISMS
What are HETEROTROPHS? CONSUMERS, MUST EAT TO SURVIVE
What are HERBIVORES? EAT PLANTS
What are OMNIVORES? EAT BOTH PLANTS AND ANIMALS
What are CARNIVORES? EAT MEAT
What are SCAVENGERS? EAT THE REMAINS OF DEAD ORGANISMS
What are DECOMPOSERS? BREAK DOWN THE REMAINS OF DEAD ORGANISMS AND PUT THE
NUTRIENTS BACK INTO THE SOIL
What are the BYPRODUCTS of photosynthesis? “GO!” GLUCOSE AND OXYGEN
What is the ENERGY CONVERSION for photosynthesis? SOLAR OR RADIANT ENERGY TO
CHEMICAL ENERGY
What would ALGAE need for photosynthesis to occur? CARBON DIOXIDE, SUNLIGHT, WATER
What is BIODIVERSITY? THE NUMBER OF DIFFERENT SPECIES IN AN AREA.
Is it healthy or unhealthy to have a high number of different species in an area? HEALTHY TO
HAVE DIFFERENT SPECIES.
Is it better to have a diverse gene pool or a uniform gene pool and why? DIVERSE BECAUSE
THEY CAN ADAPT BETTER AND ARE MORE RESISTANT TO DISEASE. LACK OF DIVERSITY IS NOT
GOOD FOR SURVIVAL.
What would happen to a deer that ate different types of grasses, but then one grass died out?
IT COULD SURVIVE ON DIFFERENT TYPES OF GRASS.
Which would have more biodiversity, a Christmas tree farm or a wooded forest? Why? A
WOODED FOREST BECAUSE IT HAS MORE VARIETY OR BIODIVERSITY IN THE FOREST THAN A
FARM THAT ONLY HAS ONE TYPE OF TREE.
What type of environment would it be beneficial for a rabbit to change from brown fur to white
fur in winter? A RABBIT COULD BE CAMOUFLAGED IN SNOW, SO SOMEWHERE WHERE IT
WOULD SNOW, LIKE UP NORTH.
Where is the MOST energy in an energy pyramid? AT THE BOTTOM (PRODUCER LEVEL)
Where is the LEAST energy in an energy pyramid? AT THE TOP (3RD OR 4TH LEVEL CONSUMER)
What PERCENT of energy is lost at each level? 10%
What is a FOOD CHAIN? A FEEDING RELATIONSHIP BETWEEN DIFFERENT SPECIES.
What is a FOOD WEB? INTERCONNECTING FOOD CHAINS. WHEN MANY ANIMALS FEED ON
MORE THAN ONE FOOD TYPE.
What do the ARROWS in a food chain or food web show? THE DIRECTION OF ENERGY FLOW
FROM ONE ORGANISM TO ANOTHER.
What would happen to the number of bears in the area if the fish died? THERE WOULD BE LESS.
26. Which POPULATION in the ecosystem would increase the most if the fish died? THE
PRODUCERS
27. How do you know if an ecosystem is HEALTHY? IF THERE IS A LARGE DIVERSITY OF SPECIES
28. In what part of the world would there be MORE biodiversity? TROPICAL RAINFOREST, IT IS
CLOSER TO THE EQUATOR.
29. What is a LIMITING FACTOR? Give some examples. AN ENVIRONMENTAL FACTOR THAT TENDS
TO LIMIT POPULATION SIZE. EX. DISEASE, TEMPERATURE, WATER, AVAILABILITY OF FOOD.
30. What is a BIOME? A COMPLEX ECOSYSTEM WITH SPECIALIZED PLANTS AND ANIMALS THAT CAN
LIVE IN THAT AREA
31. What is a MICROHABITAT? A SMALL SCALE ENVIRONMENT, LIKE A DEAD ANIMAL OR A TREE
STUMP
32. What is a NICHE? THE ROLE OF THE ORGANISM, ITS PLACE IN NATURE
33. What is the CARBON CYCLE? THE EXCHANGE OF CARBON BETWEEN BIOTIC AND ABIOTIC
FACTORS IN THE ECOSYSTEM
34. What type of things contain CARBON? ALL LIVING THINGS
35. How is carbon TRANSFERRED from animals to plants? BY CARBON DIOXIDE, ANIMALS BREATH IT
OUT, PLANTS TAKE IT IN
36. True or false. Photosynthesis, respiration, and decomposition are all CRITICAL to the carbon
cycle. TRUE
37. What does RESPIRATION add to the atmosphere? ADDS CARBON DIOXIDE TO THE
ATMOSPHERE.
38. What is the SEQUENCE OF EVENTS in the NITROGEN CYCLE? NITROGEN IN THE AIRBACTERIA
IN THE SOILPLANTSANIMALS
39. Does the NITROGEN cycle use BACTERIA? YES
40. What is COMPOST? NATURE'S PROCESS OF RECYCLING DECOMPOSED ORGANIC MATERIALS
INTO A RICH SOIL
41. You are setting up a snail aquarium at home. Your aquarium kit contains a bag of snail eggs on
an Elodea plant. The instructions say to pour the contents, including the Elodea, into the
aquarium, but you’re not sure why you need the Elodea. Why might Elodea plants be important
in maintaining a healthy ecosystem? THEY PROVIDE OXYGEN TO THE SNAILS.
42. What do the snails provide the plants? THEY PROVIDE CARBON DIOXIDE TO THE ELODEA.
43. What is EVAPORATION? WHEN THE SUN HEATS UP WATER IN RIVERS OR LAKES OR THE OCEAN
AND TURNS IT INTO VAPOR OR STEAM. (LIQUID TO A GAS)
44. What is TRANSPIRATION? PLANTS LOSE WATER OUT OF THEIR LEAVES. (LIQUID TO GAS)
45. What is CONDENSATION? WATER VAPOR IN THE AIR GETS COLD AND CHANGES BACK INTO
LIQUID, FORMING DENSE CLOUDS. (GAS TO A LIQUID)(EX. SWEATING ON THE SIDE OF A GLASSENERGY IS RELEASED)
46. What is PRECIPITATION? WHEN SO MUCH WATER HAS CONDENSED THAT THE AIR CANNOT
HOLD IT ANYMORE. THE CLOUDS GET HEAVY AND WATER FALLS BACK TO THE EARTH IN THE
FORM OF RAIN, HAIL, SLEET OR SNOW AND GOES BACK INTO THE GROUND. CAN BE STORED
UNTIL NEEDED.
