  2. Ecology? • Ecology:is the scientific study of the relation of living organisms with each other and their surroundings. • Ecosystems: are defined by a web, community, or network of creatures that arrange into a self-organized and complex systems and several levels of bigger systems constituting systems of smaller systems within them.

  3. Vocabulary! • You will need your vocabulary sheet here.  we will be adding words to our vocabulary sheet as we go through this unit. Every time you see a word that is on our vocab. let me know and we will define it together. • Let’s read the vocabulary words together. • Food Chain: is a series of plants and animals that are linked together because they feed on each other. • “Weird Friends Unlikely Allies in the Animal Kingdom”

  4. Weird Friends! • What friendship was the most interesting? • How do the animals help each other? • If I were a fisherman and I decided to hunt Sperm Whales until no more existed. What do you think would happen to the Red Phalaropes? • What happens if the Red Phalaropes starve because they don’t have the parasites form the sperm Whale to eat? • What is being effected with the process that we just talked about?

  5. Balance of Nature • There are 4 things nature needs to stay in balance. • food, water, space, shelter • This scale represents the world we live in. Right now, it • is balanced because these animals help one another.

  6. Balance of Nature • But what happens if the Sperm Whale goes away?

  7. Balance of Nature • What happened now that the Sperm whale is extinct?

  8. Balance of Nature • Before your house was built it was all trees and fields like what I have put on the scale. What if I bulldoze some of the trees and put houses there instead?

  9. Balance of Nature • Before your house was built it was all trees and fields like what I have put on the scale. What if I bulldoze some of the trees and put houses there instead?

  10. Balance of Nature • Houses and trees can still work together and balance each other out. But, what if I bulldoze the rest of the trees and put houses there instead?

  11. Balance of Nature • The world still looks balanced because there are still other trees that are alive. What if these trees were fruit trees and we needed their fruit to survive. Is the world still in balance? • Houses and trees can still work together and balance each other out. But, what if I bulldoze the rest of the trees and put houses there instead?

  12. Food Chain

  13. 3 Keys to theFood Chain! • Producer: • it is a plant that makes its own food. • Consumer: • is an animal that eats the food • Decomposer: • eats dead plants and animals

  14. Producer! • What are some examples of Producers? Would these be eaten by Omnivores? Carnivores? Herbivores? Herbivores

  15. Consumers! • What types of animals that we learned about earlier this year would be Consumers? • Insects • Birds • Mammals • Reptiles • Amphibians What kinds of animals would consumers be? Omnivores? Carnivores? Herbivores? All Three !!!!!!!!!!

  16. Decomposers! • Animals that eat food-they cannot make food on their own like a plant or tree can. • For example? What kinds of animals would decomposers be? Omnivores? Carnivores? Herbivores? All Three !!!!!!!!!!

  17. Habitats! Is this the habitat you live in? Is this the habitat you live in? Is this the habitat you live in? Is this the habitat you live in? Is this the habitat you live in?

  18. Decomposer Experiment • Decomposers eat, digest and munch, all of the organic (natural) garbage that humans, animals and plants produce. They then put it back in to the air and the soil so that we can use the nutrients and chemicals again. • If we did not have these critters we’d be up to our eyeballs in dead leaves and animal bones. • We are going to do an experiment to see how decomposition works. • Question: What if Yeast (bacteria) and a banana (plant) get into a fight. • Who wins? V.S Who is going to win this fight? Why?

  19. Air Pollution! • Polluted air contains a lot of human-made materials that are unhealthy for plants and animals. • What kinds of things pollute the air? • Campfire smoke • Pollution from factories and vehicles • Acid Rain • Tobacco smoke • What can we do to help reduce the air pollution? • Ride a bike or walk • Turn off lights Experiment! How dirty is the air that you breath?

  20. Water Pollution! • Water: • 3/4th of the earth is covered in water. People, plants and animals depend onthis clean water. • What Pollutes the water? • Factories, paper mills, oil, sewer, garbage. • Pollutants cause creatures to have unhealthy drinking water, get stuck in the trash and it suffocates fish, causes eggs to be smothered. • Drinking polluted water causes illnesses and diseases for people, plants and animals around the world. • How can we help keep our water clean? • Recycle • Properly dispose of trash and other chemicals • Don’t leave the water running

  21. Land Pollution • Healthy soil maintains life on earth • What are some causes of land pollution? • Deliberate dumping • City dumps • Water pollution washes up on land • Overcrowding in cities • The things we buy in stores • How can we keep our land clean? • Recycle • Clean up after ourselves • Be careful how much trash we produce and how we dispose of it. Composting!!!!!!!!!

  22. Recycle! How can recycling help our earth? What do these words mean? What kinds of things can we recycle? Do you recycle?

  23. Review: • Vocabulary: • Food Chain: plants and animals that are linked together because they feed on each other. • Producer: a plant that makes its own food • Consumer: can not make its own food it is an animal that eats the food produced by other sources • Decomposer: eats dead plants and animals and puts the nutrition back in the soil for the cycle to start over • Habitat: Where a plant or animal lives • Herbivore: eats only plants • Carnivore: eats only meat (other animals) • Omnivore: eats both plants and meats • Air Pollution: pollution that is in the air that harms plants, humans, and animals. • Land/water Pollution: anything that is not naturaly put into the earth. • Conservation/Recycle: Using less un-natural materials. Reuse materials when you are finished with them.
