  1. Catalyst: 3/14 Look at the picture below. In your catalyst box, write out 2 columns: Living/ nonliving. Write a list of the LIVING objects you notice on the picture and the NONLIVING objects.

  2. Ecology …the study of how organisms interact with each other and their environments

  3. Introduction • Groups of animals live in specific habitats. • There are two factors included in every habitat: • Biotic factors • Living things, like…? • Abiotic factors • Nonliving things, like…?

  4. Like a set of nesting dolls… • We can think about the interactions and types of living things by organizing them into groups, smallest to largest. • An organism is any individual living thing. • Example: hummingbirds • A population includes all members of one species that live in the same area. • Example: all the hummingbirds in West Adams

  5. …bigger and bigger groups! • A community includes all of the different species that live in the same area. • Example: all the birds, ants, maple trees, dogs, etc. that live in Los Angeles • An ecosystem includes both the community and the abiotic factors. • Example: the Los Angeles community plus the cars, buildings, rocks, air…

  6. The organisms in a habitat can be organized in the following way… ecosystem community species population

  7. Organism Organism • An species is a group of the same living thing, such as alligators.

  8. Population Population Organism Organism • A population is a group of the same species that lives in one area.

  9. Community Community Population Population Organism Organism • A community is a group of different species that live together in one area.

  10. Ecosystem Ecosystem Community Community Population Population Organism Organism • An ecosystem includes all of the organisms as well as the climate, soil, water, rocks and other nonliving things in a given area.

  11. Biome Ecosystem Ecosystem Community Community Population Population Organism Organism • A biome is a major regional or global community of organisms characterized by the climate conditions and plant communities that thrive there.

  12. Tropical • Tropical Rain Forest: warm temperatures and abundant rainfall occur all year. • Plants: lush thick forests. • Animals: monkey, parrots, snakes, lizards, iguanas

  13. Grassland • Grassland: primary plant life is grass. Occurs in a variety of climates. Moderate rainfall • Plants: Buffalo grass, coneflowers, goldenrods, clover • Animals: coyotes, eagles, bison, bobcats.

  14. Desert • Desert: very dry climate. Very little rainfall. • Plants: cacti, store water or have deep root systems. • Animals: Many animals are nocturnal (why?). Insects, arachnids, reptiles, and birds.

  15. Temperate • Temperate biomes: Deciduous and Rain forests • Plants: oaks, beeches, maples, redwoods • Animals: cardinal bird, squirrel, bears

  16. Taiga • Taiga: cooler climates. Winters are long and cold, often lasting 6+ months. 30-85 inches rainfall/year. • Plants: Coniferous trees. • Animals: animals with heavy furs

  17. Tundra • Tundra: subzero temperatures. Very little rainfall • Plants: arctic frost • Animals: artic fox, snow owl

  18. Food webs • All organisms need FOOD to survive! • Food webs show what eats what.

  19. Eat or be eaten • Here are some important terms that will help you describe interactions in a food web. 1. Producer (autotroph) • can make its own food • forms the base of the food web

  20. Mmmmm…delicious. 2. Consumer (heterotroph) • cannot make its own food There are several words that describe consumers… • Prey: the hunted • Predator: the hunter • Herbivore: eats plants • Carnivore: eats animals • Omnivore: eats both plants and animals

  21. Hey, you gonna eat that? 3. Decomposer • Breaks down dead organisms • Examples: bacteria, maggots, fungi, worms • Complete the circle of life by returning nutrients to the soil

  22. Your mission… • Label the organisms on the coloring sheet you don’t know. (use the next slide to help you) • Color in the organisms. • In your Notebooks: • WRITE THREE examples of how the organisms might interact. Use vocabulary words from your notes. • Use the organisms to create a sample food web. (must show at least 5 organisms)

  24. *How do different species of organisms interact with each other? Agenda [insert date] • Intro to ecology: notes • Food webs • Coloring sheet
