    extinct
  25. A species that is in danger of becoming endangered.
    threatened species
  26. What is Symbiosis?
    A relationship between two kinds of organisms that last over time.
  27. Explain the difference between mutualism, parasitism and commensalism.
    • Mutualism - a relationship that benefits both
    • Parasitism - a relationship that one organism benefits from the other and the other is harmed
    • Commensalism - a relationship and only one benefits but the other is not harmed.
  28. How can the change in one population in an ecosystem affect other populations in the same ecosystem.
    If the fish population goes down, then the food chain would suffer and affect the other population of animals in a bad way because there is not enough food.
  29. How do chemicals affect or endanger living things?
    For example: water pollution can affect stream and lake animals the algae grows a lot because of the fertilizer, then when it dies it begins to decay in the water and uses the oxygen that the other animals and plants need to survive.
