  • This food chain shows the sun, a producer, and consumers. What important part of the food chain was left out of this image?
    Decomposer- needed to break down and recycle nutrients back into the soil
  • Name three examples of decomposers.
    bacteria, fungi, worms, etc...
  • Which animal populations are FIRST to be affected if the plankton in the aquatic ecosystem were to become extinct?
    Penguins, Krill
  • Name three examples of producers.
    plant, tree, grass, bushes, phytoplankton, etc...
  • In the energy pyramid here, which organisms have the most energy available?
    Carnivores
    Herbivores Top Predator
    Producers
    Herbivores
  • This diagram shows the amount of energy that moves from one feeding level to another in a food web.
    Energy Pyramid
  • What happens to a population when there is more food in an ecosystem?
    The population will increase
  • What does an omnivore eat?
    Both plants and animals
  • What are some examples of limiting factors for populations in an ecosystem?
    Competitions for food, space, water, etc... are all limiting factors for a population
  • Name the different parts of this food chain.
    plant= producer; snail= primary consumer; bird= secondary consumer; fox= tertiary consumer; bacteria= decomposer
  • What part of the food chain does this image represent?
    Consumer
  • Name three examples of consumers.
    shark, owl, humans, etc...
  • What part of the food chain does this image represent?
    Producer
  • What is a food web in an ecosystem?
    A food web is all of the food chains interacting together in an ecosystem.
  • The largest group of organisms found in a food web would be:
    Producers
    Secondary Consumers
    Primary Consumers
    Tertiary Consumers
  • What does a decomposer do in an ecosystem?
    Breaks down and recycles dead organic matter and waste back into soil as nutrients for plants to use again
  • What animal populations are first to be affected in this coniferous forest ecosystem if the seeds were to completely disappear?
    Mouse and squirrel
  • What animal populations are first to be affected in this coniferous forest ecosystem if the grass were to completely disappear?
    Mouse and squirrel
  • What happens to a population when there is less food in an ecosystem?
    The population will decrease
  • In the energy pyramid here, how much of the energy in the producers gets passed to the herbivores?
    20%
    10%
    100%
  • What part of the food chain does this image represent?
    decomposer
  • What is a food chain in an ecosystem?
    A food chain shows how different organisms eat each other within an ecosystem.
  • What is always at the start of a food chain?
    A producer (plant) that used energy from the sun to create food through photosynthesis.
  • What would happen in this aquatic ecosystem food web if the blue whale became extinct?
    Blue whales eat krill so there would be more krill. Krill eat plankton so there would be less plankton.
  • Name the different parts of this food chain.
    water plant= producer; bug= primary consumer; fish= secondary consumer; pelican= tertiary consumer
  • Which animal populations are FIRST to be affected if the krill in the aquatic ecosystem were to become extinct?
    Seal, Squid, Seagull, Blue Whale
  • What is a producer?
    A plant or plant-like organism. Producers make their own food.
  • Why is the sun important for an ecosystem?
    The sun provides energy for plants to grow.
  • What does a carnivore eat?
    Other animals (meat)
  • What does a herbivore eat?
    Plants
  • What is a consumer in a food chain?
    An organism that eats producers or other consumers for their energy.
