  • The other two types include number pyramids and biomass pyramids.
  • If you want to go into a little more detail explain to student the 3 stages of cellular respiration. For photosynthesis explain to students the difference between the light and dark independent reactions.

  • FOOD WEBSWHAT DOES THIS DIAGRAM HOW ARE THE FOLLOWINGREPRESENT? RELATED? • PRODUCER • CONSUMER • OMNIVORE, HERBIVORE, CARNIVORE • FOOD CHAIN • FOOD WEB • DECOMPOSER • DETRITIVORE • CARRYING CAPACITY
  • Food web in a mountain forest • Which type of organism is a decomposer in this food web? A. Earthworm B. Grass C. Mouse D. Snake
  • AnswerA. EarthwormB. GrassC. MouseD. Snake
  • Food web in a field • Which of the following changes would decrease the carrying capacity of the field for all of the populations that live there?A. An introduction of wild cats to the fieldB. A severe decrease in rainfall, resulting in droughtC. An outbreak of an often fatal viral infection among miceD. A thinning of the shells of owls’ eggs, resulting in fewer births

  • ENERGY IN ECOSYSTEMSWHERE DO AUTOTROPHS GETTHERE ENERGY FROM? WHY IS ENERGY IMPORTANT? • THE FLOW OF ENERGY IN A FOOD CHAIN IS ONE DIRECTION • ENERGY FLOWS FROM THE SUN OR INORGANIC COMPOUNDS TO AUTOTROPHS (PRODUCERS) AND THEN TO VARIOUS HETEROTROPHS (CONSUMERS) • REMOVING DECOMPOSERS WOULD STOP THE CYCLING OF MATTER IN NATURE.
  • Examine Food Web • Which of the following pairs of consumers in this food web has the greatest amount of energy available for them to consume? a. Hawk and mountain lion b. Rabbit and grasshopper c. Snake and songbird d. Trees and grass
  • Answera. Hawk and mountain lionb. Rabbit and grasshopperc. Snake and songbirdd. Trees and grass
  • Flow of energy through a food chain and the cycling of matter in nature • How would the absence of decomposers most significantly affect the flowchart?A. The flow of energy would be affected.B. The dissipation of energy would be less.C. It would stop the cycling of matter in nature.D. The supply of nutrients for the producers would be less.
  • AnswerA. The flow of energy would be affected.B. The dissipation of energy would be less.C. It would stop the cycling of matter in nature.D. The supply of nutrients for the producers would be less.
  • ECOLOGICAL PYRAMIDSWHAT ARE TROPHIC LEVELS? WHAT ARE ECOLOGICAL PYRAMID? • THE PRODUCERS HAVE THE HIGHEST ENERGY LEVEL • ONLY 10% OF ENERGY IS PASSED ON TO THE NEXT TROPHIC LEVEL. WHY? • WHO EATS SECOND LEVEL CONSUMERS? • WHO EATS PRODUCERS? • WHAT ARE THE THREE TYPES WHAT TYPE OF PYRAMID IS THIS? OF ECOLOGICAL PYRAMIDS?
  • Different trophic levels in food chain • Which statement about this diagram is true?A. The biomass at a trophic level is less than the level above it.B. The population at a trophic level is greater than the level below it.C. The amount of energy available at a trophic level is less than the level below it.D. The organism at each trophic level belongs to a different kingdom than the level above it.
  • AnswerA. The biomass at a trophic level is less than the level above it.B. The population at a trophic level is greater than the level below it.C. The amount of energy available at a trophic level is less than the level below it.D. The organism at each trophic level belongs to a different kingdom than the level above it.
  • ENERGY FLOW • Which of these best explains what happens between trophic levels as energy moves up a food chain?A. Energy is transferred completely from one organism to the next.B. Energy is transferred but some of it is lost to the environment.C. Energy is recycled uniformly throughout.D. Energy is produced in greater quantities.
  • AnswerA. Energy is transferred completely from one organism to the next.B. Energy is transferred but some of it is lost to the environment.C. Energy is recycled uniformly throughout.D. Energy is produced in greater quantities.
  • Feeding Patterns Observed • Which of the following best explains the difference in the amount of available energy in the trophic levels of the desert ecosystem?A. There is less energy available in the producers because their tissues are less dense than those at higher trophic levels.B. There is more energy available in the second trophic level because less energy is needed for hunting compared to the higher trophic levels.C. There is more available energy in the birds of prey because they have greater muscle mass for storing energy than organisms in lower trophic levels have.D. There is less available energy in the fouth trophic level because of the loss of energy through metaoblism in each of the lower trophic levels.
  • AnswerA. There is less energy available in the producers because their tissues are less dense than those at higher trophic levels.B. There is more energy available in the second trophic level because less energy is needed for hunting compared to the higher trophic levels.C. There is more available energy in the birds of prey because they have greater muscle mass for storing energy than organisms in lower trophic levels have.D. There is less available energy in the fourth trophic level because of the loss of energy through metabolism in each of the lower trophic levels.
  • ECOLOGICAL SUCCESIONWHATS HAPPENING OVER TIME? EXPLAIN • ECOLOGICAL SUCCESSION • PRIMARY SUCCESSION • SECONDARY SUCCESION • PIONEERS SPECIES
  • Ecological Succession • A new island breaks through the surface of the sea near Iceland after a long series of volcanic eruptions. Which of theseA. Birds organisms is most likelyB. Insects to be the first one toC. Lichens colonize the island andD. Flowering plants start a succession?

  • PHOTOSYNTHESIS & CELLULAR RESPIRATION WHAT EQUATION IS THIS? WHAT HAPPENS IF YOU FLIP IT? EXPLAIN HOW THIS WORKS.HOW DO ORGANISM RELEASE ENERGY? WHERE DOES PHOTOSYTHESIS TAKE PLACE? WHERE DOES CELLULAR RESPIRATION TAKE PLACE?

  • Photosynthesis • Sam places a small green plant inside a test tube and seals the test tube inside a flask. The flask has a glass tube sticking out of the stopper, so he can periodically analyze the gas in the flask.

What will his analysis most likely show?A. During the night, the amount of both gases remain constant.B. The amount of both gases in the flask remains constant over a 24-hr period.C.
