QUIET BALL UNIT 17-19 EXAM REVIEW 7 TH GRADE
2
CARBON DIOXIDE IS PRODUCED WHEN WHAT IS CHEMICALLY BROKEN DOWN? BIOMASS
3
WHAT HAPPENS TO THE AMOUNT OF CARBON IN THE ENVIRONMENT DURING THE CARBON CYCLE? The amount of carbon in the carbon cycle stays the same.
4
WHEN AN ORGANISM DIES, HOW DOES MOST OF THE CARBON FROM THE BODY RETURN TO THE ENVIRONMENT? Decomposers break the body down into simpler compounds.
5
WHY DOES A COMPOST PILE GIVE OFF STEAM IN THE WINTER ? Stored chemical energy is being converted to thermal energy by the decomposition of biomass.
6
WHICH ORGANISMS BELONG TO THE SAME FOOD CHAIN? Leaves, grasshopper, frog, snake Berries, squirrel, fox Leaves, mouse, fox
7
HOW MANY PRODUCERS ARE IN THIS WEB ? Two, the leaves and the berries
8
HOW MANY TROPHIC LEVELS ARE IN THIS FOOD WEB ? Five Autotrophs (plants), primary consumers (grasshopper, mouse, squirrel, rabbit), secondary consumers (frog, mouse, fox,), tertiary consumers (owl, snake). Quaternary (owl).
9
WHAT TYPE OF ORGANISM IS NOT MENTIONED IN THE FOOD CHAIN? A Decomposer
10
WHAT WOULD HAPPEN IF THERE WERE AN INCREASE OF FROGS IN THIS FOOD WEB? There would be less grasshoppers and more food available for the snakes and owls
11
WHY DO SOME PLANTS GROW VINES ALONG FENCES AND WOODS? To get support from nearby objects
12
HOW DOES TURGOR PRESSURE HELP A PLANT? The water provides support for the plant
13
HOW DO PLANTS RESPOND TO GRAVITY AND SUNLIGHT? Roots grow down and leaves grow up.
14
WHY DOES THE PHOTOSYNTHESIS FORMULA HAVE THE WORD SUNLIGHT IN THE EQUATION? Photosynthesis can not happen without sunlight.
15
WHAT HAPPENS TO THE ENERGY ABSORBED BY PLANTS DURING PHOTOSYNTHESIS? It is transformed into chemical energy.
16
WHICH ORGANISMS ARE RESPONSIBLE FOR TRANSFORMING RADIANT ENERGY INTO CHEMICAL ENERGY? The leaves and the berries (or the producers, or the autotrophs)
