  • Which is a more realistic representation of the transfer of energy within an ecosystem: a food chain or a food web?
    Food Web
  • Which organisms go through photosynthesis: consumers, producers, or decomposers?
    Producers
  • An animal that only eats meat
    Carnivore
  • How many producers are in this food web?
    3 (carrots, grasses, grains)
  • What is the process that producers go through to make their own food?
    Photosynthesis
  • a living thing that breaks down dead plants and animals into simpler matter
    Decomposer
  • What is a series of events in which one organism eats another and obtains energy and nutrients?
    Food Chain
  • What is a consumer that only eats other animals?
    Carnivore
  • What is a consumer that eats both plants and animals?
    Omnivore
  • What is at the beginning of all food chains? The Earth would not be able to function without the energy from this very large star!!
    The sun
  • What is a consumer that only eats plants?
    Herbivore
  • What is an organism that obtains energy by feeding on other organisms?
    Consumer
  • What is an organism that can make its own food, and is the source of food for other organisms?
    Producer
  • What is an organism that is hunted and eaten?
    Prey
  • a group of living things in which the first is eaten by the second, the second is eaten by the third and so on
    Food Chain
  • What is an organism that breaks down dead organisms and returns the nutrients back to the soil?
    Decomposer
  • Horrible snake disease hit the Earth and all the snakes were wiped out. What would increase?? What would decrease??
    INCREASE - MICE DECREASE - KITE OR HAWK
  • What are organisms that eat secondary consumers (carnivores, omnivores)?
    Tertiary Consumers
  • An animal that eats plant AND meat
    Omnivore
  • What is an organism that hunts and eats other organisms?
    Predator
  • Several food chains together
    Food Web
  • What is a carnivore that feeds on dead organisms?
    Scavenger

    Abiotic Factors
  • There are 2 apex predators in this food web. Who are they?
    Foxes, Owls
  • What are organisms that eat producers (herbivores)?
    Primary Consumers
  • A carefully balanced system where plants and animals live and work together; this is also known as a community
    Ecosystem
  • What are organisms that eat primary consumers (carnivores, omnivores)?
    Secondary Consumers
  • 2 products of photosynthesis:
    oxygen, glucose (sugar)
  • What is the ultimate source of energy for this food chain?
    Sun
  • The shrew is what type of consumer?
    Primary Consumer/Herbivore
