Presentation Transcript

  1. Living Things and the Environment A presentation by Ms. Musich

  2. Visualize! • Picture a forest scene in your head. • What kind of plants do see? • What kinds of animals do you see? • What kind of non-living materials do you see?

  3. Fontainebleau forest, Ile de France

  4. Ecosystem • An ecosystem is all the living and non-living things that interact in a particular area. • Animals? • Plants? • Rocks? • Oxygen? • Soil? • Minerals?

  5. Habitats • Organisms live within a specific place within an ecosystem. • An organism obtains food, water, shelter, and other things it needs to live, grow, and reproduce from its surroundings. • The place where an organism lives and provides its needs is called its habitat.

  6. For example… A prairie dog’s habitat is in underground tunnels. A mushroom’s habitat is in moist soil, tree bark, or mossy rocks.

  7. Habitats Continued • An ecosystem may contain MANY habitats. • An animal or plant lives in a particular ecosystem because it meets the organisms needs. Habitat Video

  8. Brainstorm! • Types of Ecosystems (ex. Forest)

  9. Brainstorm! • Types of habitats (ex. Cave)

  10. Checking for Understanding! • What is the difference between a habitat and an ecosystem? • HOMEWORK: Pick an ecosystem and create a detailed illustration including at least 3 living items and 3 non-living items. This assignment must be colored in order to receive full credit. NO WRITING REQUIRED.

  11. Biotic Factors • Animals interact with both living and non-living elements in the environment. • The living parts of an ecosystem are called biotic factors.

  12. Quick GAME! • I’m going to call out a letter of the alphabet. You will have 45 seconds to pick a biotic factor starting with that letter. Try to be creative because if you and another student have the same answer, then you’re out. • Winners will receive prizes!

  13. Biotic Factors • Include: • All plants • All animals • Decomposers • Worms, Fungi, Protists, & Bacteria

  14. Abiotic Factors • All non-living parts of an ecosystem are called abiotic factors. • These factors include: • Water ~ very important for photosynthesis • Sunlight ~ without plants we couldn’t survive • Oxygen ~ animals need it to survive • Temperature • Soil ~ provides homes for many animals

  15. With which abiotic factors is the frog interacting with here?

  16. Populations • What do you already know about populations? • A species is a group of organisms that are physically similar and can reproduce with each other to produce offspring. • A population is all the members of one species in a particular area.

  17. For example… • “Designer Dogs” • AKA Goldendoodle & Morkie • Dogs can be bred with one another because they are all the same species: Canisfamiliaris

  18. + = Golden Retriever Standard Poodle Goldendoodle + = Hippopotamus Rhinocerous

  19. For Example… The Giant Panda is a species. Panda Facts! The Grizzly Bear is its own species.

  20. Bears: What’s the Difference? • Grizzly Bear’s Classification:  Phylum:Chordata this means the animal has a backbone. Class:Mammalia this means the animal is a mammal Order:Carnivora this means the animal is a carnivore Family:Ursidae this means the animal is in the bear family Genus:Ursus this designates the bear as a grizzly • We classify organisms in order to group them by similar characteristics. • Check out these other bears…

  21. So… • If a cat is an organism within a species… My oldest cat, Lucky 

  22. Then… • All of the cats within a particular area (my house) are considered to be a population. Figaro Lucky Button Benny Stella

  23. Other examples of populations • All the prairie dogs in Texas • All the pigeons in New York City • All the daisies in a field

  24. NOT A POPULATION! • All the trees in a forest • Why is this not a population? • The area in which a population lives can be as small as a single blade of grass or as large as the whole planet. • Brainstorm other types of populations.

  25. What makes up a community?

  26. Communities • All of the different populations that live together in an area make up a community. • Remember, ecosystems are made up of more than just one population of species. • For example, a ocean ecosystem is made up of more animals than just whales.

  27. A Prairie Community • A prairie community may include: • Prairie Dogs • Hawks • Tall grasses • Badgers • Snakes • Insects • And more… All of these are populations on their own, but together make up a community.

  28. Ecology • Ecology is the study of how living things interact with each other and the environment.
