  • 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
  • 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...
  • 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
  • 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 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 are some examples of limiting factors for populations in an ecosystem?
    Competitions for food, space, water, etc... are all limiting factors for a population
  • 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.
  • What is a food web in an ecosystem?
    A food web is all of the food chains interacting together in an ecosystem.
  • Name the different parts of this food chain.
    water plant= producer; bug= primary consumer; fish= secondary consumer; pelican= tertiary consumer
  • What part of the food chain does this image represent?
    Producer
  • What happens to a population when there is more food in an ecosystem?
    The population will increase
  • Name three examples of decomposers.
    bacteria, fungi, worms, etc...
  • What does a carnivore eat?
    Other animals (meat)
  • Name three examples of consumers.
    shark, owl, humans, etc...
  • What does an herbivore eat?
    Plants
  • 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 happens to a population when there is less food in an ecosystem?
    The population will decrease
  • What does an omnivore eat?
    Both plants and animals
  • 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 is a consumer in a food chain?
    An organism that eats producers or other consumers for their energy.
  • Which animal populations are FIRST to be affected if the krill in the aquatic ecosystem were to become extinct?
    Seal, Squid, Seagull, Blue Whale
