  • What is a secondary consumer?
    A secondary consumer is a carnivore (that eat primary consumers; the herbivores).
  • What is a food chain and a food web?
    A foos chain is the relationship between a plant, the herbivore that eats it and the carnivore that eats it. A food web is a "group" of food chains.
  • During photosynthesis, what do plants breathe out?
    Oxygen.
  • What is a producer in a food web?
    Producers are living things that produce their own food (with energy from the sun and nutrients from the soil). Example: plants.
  • When an animal's fur is the same colour as the environment this is called what?
    Camouflage
  • What is a biome?
    A large ecosystem made up of smaller ecosystems.
  • What is a primary consumer?
    A primary consumer is a hervibore animal (that eats producers).
  • What is the biosphere?
    All living things on Earth including those in the atmosphere, hydrosphere and geosphere. *The largest ecosystem, because it contains all the different biomes.
  • Give an example of a decomposer
    Worms are decomposers
  • What is a tertiary consumer?
    A tertiary consumer is a carnivore that eats secondary consumers (other carnivores).
  • What is a habitat?
    The place where a community lives. A habitat can be a forest, water in a pond, a mountain, the rocks or soil.
  • What is a community?
    All the populations that live in a habitat. For example: a community can be made up of a population of foxes, a population of eagles, a population of trees...
  • During photosynthesis, what do plants breathe in?
    Carbon dioxide
  • What is the hydrosphere?
    All water on Earth including saltwater and freshwater
  • What is the atmosphere?
    Layer of gases that surrounds the Earth.
  • Where does photosynthesis happen?
    In the chloroplasts of leaf cells.
  • What is a population?
    All the individuals of the same animal or plant species living in a place. A fox is an individual; a group of foxes that live in the same are is a population.
  • Give an example of parasitism
    A mosquito sucks blood from a dog.
  • Give an example of mutualism
    A bee pollinates a flower
  • What is a decomposer?
    A decomposer is a living thing that decompose other elements of the food web when they die. This way, the nutrients go back into the soil.
  • What forms an ecosystem?
    The climate, living things and the place they live.
  • Which two factors are very important for climate?
    Precipitation and temperature.
  • What is at the top of the food web?
    The sun because it allows producers to make food
  • What is the difference between a lake and a river?
    Lakes are still fresh water and rivers are moving fresh water.
  • What are the three layers of the Geosphere?
    Nucleus/Core, Mantle, Crust
