  • Which Ecosystem is more sustainable and why?
    1 because there is more than one producer
  • A food chain should always begin with -
    the Sun
  • These organisms eat decaying matter.
    decomposers
  • Primary consumers eat secondary consumers. TRUE or FALSE?
    FALSE
  • Species diversity hurts the ecosystem. TRUE or FALSE?
    FALSE
  • Primary consumers eat-
    producers
  • Arrows in a food chain or food web show the flow of energy from one organism to the next. TRUE or FALSE?
    TRUE!
  • An organism can be a primary consumer and a secondary consumer. TRUE or FALSE?
    TRUE! Upland sandpipers are an example because they eat grass and grasshoppers.
  • How much energy is lost as you travel up- the trophic level energy pyramid?
    10%
  • What is biodiversity?
    A wide variety of species in an area.
  • Name the number one factor that plants often compete for.
    sunlight
  • Explain the difference between a food web and a food chain.
    answers may vary
  • A forest that has been cleared by logging increases biodiversity. TRUE or FALSE?
    FALSE!
  • The place where an organism lives is called a-
    habitat
  • Which Ecosystem is more sustainable and why?
    2 because there primary consumers can eat more than just one thing
  • What will happen to the deer if the bush dies?
    The deer will eat the grass
  • These organisms only eat meat.
    carnivores
  • Which Ecosystem is more sustainable and why?
    1 because almost all of the animals eat more than one thing
  • Which Ecosystem is more sustainable and why?
    1 because there are more producers available
  • Organisms DO NOT compete for abiotic factors. TRUE or FALSE?
    FALSE
  • Which Ecosystem is more sustainable and why?
    2 because there are more primary consumers
  • In what biome would I find the following organisms?
    Tundra
  • Which trophic level has the LEAST amount of energy?
    tertiary consumer
  • Which trophic level has the greatest amount of energy?
    producers
  • After a forest fire, primary consumers will MOSTLY compete for -
    food
  • What is a producer?
    plants, organisms that can make their own food by photosynthesis
  • Which Ecosystem is more sustainable and why?
    1 because it has more producers
  • Which Ecosystem is more sustainable and why?
    1 because there are more primary consumers
  • High biodiversity is bad. TRUE or FALSE?
    FALSE
  • What will happen if the green plant dies?
    the whole ecosystem will collapse
  • What will the fox eat if the birds die?
    rabbits
  • Which Ecosystem is more sustainable and why?
    1 because most organisms have more than one food source
  • Tertiary consumers receive energy from secondary consumers. TRUE or FALSE?
    TRUE
  • A stable ecosystem is called-
    sustainable
  • Secondary consumers eat-
    Primary consumers
  • Ecosystems with more species are more sustainable. TRUE or FALSE?
    TRUE!
  • As you get closer to the equator, biodiversity-
    increases
  • These organisms eat both plants and animals.
    omnivores
  • A food web can have no more than 15 organisms of different species. TRUE or FALSE?
    FALSE
  • Trophic levels show the different levels of how organisms get their energy. TRUE or FALSE?
    TRUE
  • The higher the biodiversity, the higher the---
    sustainability
  • What is wrong with this food web?
    the arrows are pointing the wrong way
  • Fish can move near other aquatic organisms when oxygen levels are low. TRUE or FALSE?
    TRUE
  • Which Ecosystem is more sustainable and why?
    Ecosystem 2 because there is more biodiversity
  • An ecosystem with low biodiversity is very strong. TRUE or FALSE?
    FALSE
  • Which Ecosystem is more sustainable and why?
    1 because each carnivore has a variety of prey
