Energy Flow: Autotrophs

Food chains (2) Begins with the Sun’s energy Solar/radiant energy converted to chemical energy by primary producers Amount of available energy decreases.

Energy and Ecology Ecosystem Components Producers – Basis of an ecosystem’s energy – Autotrophs: perform photosynthesis to make sugars – Chemotrophs:

 Energy is never made or destroyed, it simply changes from one form to another. When we eat food, the chemicals are broken down, and energy is released.

QUIET BALL UNIT EXAM REVIEW 7 TH GRADE

CARBON DIOXIDE IS PRODUCED WHEN WHAT IS CHEMICALLY BROKEN DOWN? BIOMASS

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.

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.

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.

WHICH ORGANISMS BELONG TO THE SAME FOOD CHAIN? Leaves, grasshopper, frog, snake Berries, squirrel, fox Leaves, mouse, fox

HOW MANY PRODUCERS ARE IN THIS WEB ? Two, the leaves and the berries

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).

WHAT TYPE OF ORGANISM IS NOT MENTIONED IN THE FOOD CHAIN? A Decomposer

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

WHY DO SOME PLANTS GROW VINES ALONG FENCES AND WOODS? To get support from nearby objects

HOW DOES TURGOR PRESSURE HELP A PLANT? The water provides support for the plant

HOW DO PLANTS RESPOND TO GRAVITY AND SUNLIGHT? Roots grow down and leaves grow up.

WHY DOES THE PHOTOSYNTHESIS FORMULA HAVE THE WORD SUNLIGHT IN THE EQUATION? Photosynthesis can not happen without sunlight.

WHAT HAPPENS TO THE ENERGY ABSORBED BY PLANTS DURING PHOTOSYNTHESIS? It is transformed into chemical energy.

WHICH ORGANISMS ARE RESPONSIBLE FOR TRANSFORMING RADIANT ENERGY INTO CHEMICAL ENERGY? The leaves and the berries (or the producers, or the autotrophs)
