  1. all right.
  2. While we're here in the fresh water bio, let's go
  3. ahead and discuss some of the levels of organization.
  4. Uh, we're gonna go ahead and click here on the
  5. green text.
  6. Levels of organisation include the organism, the population, community, ecosystem
  7. and biosphere.
  8. Um, an organism which is down on the bottom here.
  9. As we can see, it's a individual animal plant or
  10. a single celled life form.
  11. Um, it basically embodies the properties of life.
  12. That's the smallest.
  13. Then you go up to population.
  14. Population is all of the members of the same species
  15. that live in the same place at the same time.
  16. So as because you hear the by the organism is
  17. a fish.
  18. The population is gonna be all of the same species
  19. of fish living in the same lake or the same
  20. part of the leg at the same time, the community
  21. is gonna be a group of interacting species living in
  22. the same place.
  23. The same species are bound together by the network of
  24. influences that species have on one another.
  25. Um, so the community is kind of all of these
  26. different species, and it kind of looks at the the
  27. roles that they all play and how they're all intertwined
  28. ecosystem Is communities being plural?
  29. Um, of all living organisms interacting as a system, Um,
  30. in the same place, the biotic and a biotic components
  31. are linked together through nutrient cycles and energy flow.
  32. Then you have the biosphere, which is basically a worldwide
  33. some of all of the ecosystems global ecological systems, integrating
  34. all living things and their relationships is another way to
  35. define a biosphere.
  36. Let's go ahead and take a closer look at just
  37. one organism.
  38. The fish here, So the fish has Right here is
  39. a video of this, our guests a picture of a
  40. single circulatory system of the fish.
  41. Um, it's basically you're just one looping system.
  42. The heart is one of the examples of an Oregon.
  43. It actually has four parts and exit and enter.
  44. And then the two parts in the middle, which is
  45. made up though the heart is the Oregon, that Oregon
  46. is made up of a muscle and valve tissue.
  47. The cells working together is actually what makes up the
  48. muscle involved tissues, Uh, in this example here of the
