  • What types of consumers are there?
    Herbivores, carnivores, omnivores, scavengers and parasites.
  • What are herbivores? Give an example.
    These are consumers that eat plants, including leaves, flowers, fruit, pollen, nectar, seeds and roots.
  • What is another way to call heterotrophs organisms?
    They are called consumers because they consume energy from other living things.
  • What are biotic factors?
    They are living things.
  • What are carnivores? Give an example.
    These are organisms that feed on other animals.
  • What is a drought? What are the negative effects?
    Droughts are caused when the amount of water necessary for living things to survive is not available. Many plants die because they cannot perform photosynthesis
  • What is deforestation?
    Deforestation happens when we destroy forests by cutting down trees.
  • Living things that obtain their nutrients from other living things are called...
    Heterotrophs
  • Living things that can make their own nutrients are known as...
    Autotrophs
  • What are scavengers? Give an example.
    These are organisms that consume waste and dead animals.
  • What is a flood? What are the negative effects?
    Floods can leave plants and animals submerged in water, causing alteration in their food chains.
  • What is a population?
    A population is a group of individuals of the same species that live in the same space and at the same time.
  • What is another way to call autotrophs organisms?
    Autotrophs are called producers because they produce energy for other living things.
  • Is there an organization in nature?
    Yes, biotic factors interact.
  • Why are forests so important?
    Habitats of animals, creation of medicine, give us oxygen.
  • What is an ecosystem?
    An ecosystem consists of the living things in a certain place, the conditions of the place (temperature, light and humidity among other things) and the interact
  • Give five examples of autotrophs organisms.
    Teacher checks.
  • Give three examples of autotrophs organisms.
    Teacher checks.
  • What are omnivores? Give an example.
    These are organisms that consume both animals and vegetables
  • What are abiotic factors?
    They are nonliving things.
  • What is a community?

  • What are parasites? Give an example.
    These are consumers that feed on other animals but without killing them. They can live inside or outside the body they consume.
  • In what way heterotrophic and autotrophic organisms interact?
    Heterotrophic organisms consume autotrophic organisms, and sometimes they benefit from each other.
  • Name The Harmful Effects of Human Activity.
    Agriculture and the Use of Pesticides, Indiscriminate Hunting and Introduction of a New Species.
  • Name the Natural Causes that alter Food Systems.
    Glacial periods, Volcanic eruptions, Floods and droughts.
