Show Answers:

  1. Are people, trees, dogs or birds biotic or abiotic factors?
    biotic factors
  2. Water, sunlight and CO2 are abiotic factors necessary to complete the process of ________________.
  3. Are temperature, soil, oxygen, water and sunlight examples of biotic or abiotic factors?
    abiotic factors
  4. What is the study of how living things interact with each other and with their environment?
  5. The community and abiotic factors ______ an ecosystem.
  6. A poplation belongs to a community of different ____________.
  7. The smallest unit of organization is a single _____________, which belongs to a population of other members of its species.
  8. All of the different populations that live together in an area make up a _________________.
  9. All of the members of one species in a particular area are referred to as a _____________.
  10. ______________________is the process in which organisms use water along with sunlight and CO2 to make food.
  11. What are the nonliving parts of an ecosystem called?
    abiotic factors
  12. What are the living parts of an ecosystem called?
    biotic factors
  13. An organism obtains food, ________, shelter and other things it needs to live, grow and reproduce from its surroundings.
  14. What is the place where an organism lives and provides the things the organism needs to survive called?
  15. All living and nonliving things that interact in a particular area make up an ____________.
  16. What are the four levels of organization within an ecosystem called?  (from smallest to largest)

  17. What are some basic needs provided by an organism's habitat that give the organism an opportunity to grow and reproduce?
    • food
    • water
    • shelter
    • air
    • other things
  18. Why are water and sunlight two important abiotic factors to all organisms?
    All organisms need water to survive and carry out their life processes.  Plants and algae need water and sunlight to make their own food in photosynthesis.  All other organisms depend directly, or indirectly, on plants and algae for food.
  19. What is an ecologist?
    An ecologist is a scientist that studies ecology.  They look at how all biotic and abiotic factors are related.  They study how organisms react to changes in their surroundings and how they respond to changes in the conditions around them.
  20. What part of a plant is food made in the process of photosynthesis?
    the leaves
  21. What is the food called that is made in photosynthesis?

    (C6 H12 O6)
  22. What are two by-products of photosynthesis?
    H2O and O2
  23. Where is food stored after plants make food in the leaves during photosynthesis?
    in the roots
  24. What part of plants support the top part of the plant and transport, water, minerals and food made in the  leaves?
    the trunk
  25. What part of plants absorb water and minerals, anchor the plant and store food after it is made in photosynthesis?
    the roots
  26. Why is the energy of the sun important to all organisms on earth?
    The sun provides energy for photosynthesis and provides warmth for organisms on earth.
  27. What abiotic factors are important to organisms on earth?  Why?
    • water-for life processes
    • soil-home for animals/for photosynthesis
    • air-to breath as you can only live a few
    • minutes without it
    • sunlight-energy for photosynthesis/ 
    • warmth
    • temperature-determine's the organisms that can live in an area
  28. What basic needs do all living things have?
    • food-for energy
    • water-life processes/hydration/home for aquatic animals
    • air-O2 to breath/CO2 for photosynthesis
    • soil-home for animals/photosynthesis
    • other things-bacteria to help with digestion/decomposition to return raw materials to the environment
