food chain & food web

Cards (23)

  • Organisms need food in order to survive
  • Some organisms make their own food, while others eat other organisms for food
  • We can describe the relationships between organisms based on the food they eat
  • The Sun is the main source of energy for all plants, which can trap light from the Sun directly
  • All other organisms get energy from the Sun indirectly
  • Plants trap light from the Sun to make food during photosynthesis
  • Energy from the food made by plants may be used by the plants or stored in parts of the plants
  • The rabbit is a plant-eater, it gets energy from the plants it eats
  • The bear is a plant-and-animal eater, it gets energy from the plants and other animals it eats
  • The falcon is an animal-eater, it gets energy from the other animals it eats
  • Producers
    Plants that can make their own food using chlorophyll and sunlight
  • Consumers

  • If there were no producers, there would be no food for consumers
  • Predators
    Animals that hunt and kill other animals for food
  • Prey
    Animals that are killed and eaten by predators
  • Predators help to control the number of prey in a community
  • Food chain

  • Food chains always begin with a producer
  • Energy is transferred from one organism to another in food chains and food webs
  • Food web
    Interconnected food chains in a community
  • Organisms in a community depend on one another
  • When the population of one organism increases or decreases
    The populations of other organisms in the community are affected
  • Types of organisms
    • Plant-eater
    • Animal-eater
    • Plant-and-animal eater
