Ecosystem Powerpoint For Technology

  1. 1. By Erica Lamar
  2. 2. Standard III.5 Ecosystems  All students will explain how parts of an ecosystem are related and how they interact; explain how energy is distributed to living things in an ecosystem; investigate and explain how communities of living things change over a period of time; describe how materials cycle through an ecosystem and get reused in the environment; and analyze how humans and the environment interact. ◦ It is within ecosystems that communities of living things interact.
  3. 3. An ecosystem is an area where plant and  animals interact with each other. They feed, mate, and share the same place in the environment. There are many different ecosystem, like  lakes, forests, cities, etc. We will be studying one major ecosystem near us. Lake Michigan and the plants and animals that live in them. We will study: ◦ The Lamprey Plant Life ◦ Trout Animals around Lake Michigan
  4. 4. Lake Michigan is one  of 5 lakes that surround Michigan It is on the left side  of Michigan with Wisconsin on the other side. It houses many  species of animal and plant life and we will review 3 of them
  5. 5. There are several  species of Lamprey in the Great lakes: ◦ Silver Lamprey, ◦ American Lamprey, ◦ Northern Brook Lamprey and ◦ Chestnut Brook Lamprey.
  6. 6. Lamprey are a marine animal that live in fresh water all  around the world. They are not found in Africa’s coastal regions because Lamprey larvae have a fairly low tolerance for warm/ high water temperatures.
  7. 7. Lamprey have cartilage  skeleton and have a jawless mouth. Their mouth is circular with many rows of teeth. They bore into fish, mainly Lake Trout in Lake Michigan and Streams. They are a pest because they have no natural enemies and affect fishing in lakes and streams. Lamprey are NOT fish.
  8. 8. Because Lamprey feed Seeing that we have   on trout they have an already learned about affect on plants in lake the food web, what Michigan and humans. other ways might Lamprey affect the ◦ They affect fishing for natural balance in the people that enjoy have trout for dinner. Great Lakes ◦ Because there are less trout in increase the amount of small fish that live in Lake Michigan ◦ Which in turn increases plant life in Lake Michigan
  9. 9. Many Trout are  camouflage so that they blend into their environment. Unlike Lamprey,  they have jaws, fins, and are fish. But like Lamprey  they feed on fish, but Trout feed on smaller fish.
  10. 10. At two years old Trout change  color and find mate because they are ready to reproduce. The male and female mate and  the female lays her eggs in a nest in gravel in fresh water. The Alevin (larvae) hatch and live off their yolk sac. The Fry ( adolescent trout)  swim around finding their own food, mostly zooplankton. When they are adults they are  ready to reproduce again. Trout are sometimes a  migratory fish, being able to travel from lake to stream to ocean about 3 times in one life time. They live for about 7 years.
  11. 11. Trout are food for If Trout were not   not only humans apart of Lake but Lamprey, Bears, Michigan how and other wildlife would it affect all that live in and the things that around Lake depend on it? Michigan. They are important  for fisherman who need them to make a living.
  12. 12. There are many Some of these plants   plants the live in and include around Lake ◦ Algae Michigan. They all ◦ Milkweed serve their own ◦ Lily pads purpose and are important to the survival of animals they live in and around the lake. How plants affect  their ecosystem
  13. 13. Algae is important in  living animals in marine environments. ◦ It produces oxygen in water for fish and other animals to breath ◦ It is a food source ◦ A common form of algae is Seaweed (which is eaten by many people)
  14. 14. Milkweed is  important for nectar seeking bees and monarch butterflies. It is helpful to some  plants by repelling some pest like wireworms They provide beauty  and oxygen to Lake Michigan's shores.
  15. 15. They provide nice  resting places for frogs and turtles in lake They provide oxygen  like all plants and are nice to look at. They can become  invasive, blocking out sunlight trying to reach the water it’s in.
  16. 16. Algae is important If we didn’t have   for feeding. plants in Lake Michigan could Milkweed is  animals get the important for bees oxygen required to and monarch live? butterflies. Water lilies are nice  places to rest for small animals like frogs and turtles. All of them provide  oxygen!
  17. 17. Not only do animals live Some animals that live   in lake Michigan, but around Lake Michigan they live around Lake are: Michigan. ◦ Black Bears When we think of bodies ◦ White tail Deer  of water as ecosystems we often only think of the animals that live in them, but there are many animals the live outside of water to think about. How animals around  Lake Michigan affect their Ecosystem
  18. 18. Black bears are apart of  Michigan. They are spread through  out Michigan but are in high density in the upper peninsula. The shores of lake Michigan reach the upper peninsula, making it an important part of the to the survival of the black bear. Black bears feed on a  variety of things including berries, vegetation and trout.
  19. 19. They are in every  county in Michigan. They each plants,  fruit, acorns, and wild corn. They are sometime  preyed on by the black bear.
  20. 20. Black Bears feed on If Black bears didn’t   vegetation and eat trout how would trout in and around that affect the Lake Michigan. population of trout in Lake Michigan? Deer are sometimes  preyed on by Black Bears.
  21. 21. Though we don’t think much about how  plants and animals interact with each other in the environment, they do. In Lake Michigan alone many animals depend  on plants to survive, and larger animals depend on the smaller ones. They work in a beneficial way and sometimes a harmful way. The interaction of all these plants and animals in the same environment is an ecosystem.
