Presentation Transcript

  1. Warm-up: 9/10 How do you know if something is a “living” thing? Make a checklist for your answer. Living things have: • ___________ • ___________ • ___________ (etc.)

  2. Living things and Ecosystems Anchoring Question: Is coral a living or non-living thing? How do we know?

  3. Let’s see how you did: Make a T-chart in your notebook: As you watch the following video, write down a list of the different biotic and abiotic factors you see.

  4. Intro to Ecology:

  5. New cornell notes: Characteristics of Living things Essential question: How can we tell the difference between living and non-living things? *Write these notes in your notebook! Do not turn this in with your warmup/exit slip!

  6. Five Characteristics of Living things (pg. 28): • Living things respond to their surroundings. • Living things grow and develop. • Living things are able to reproduce. • Living things use energy to survive. • Living things are made of smaller building blocks called cells. *Compare these to the class list. What is the same? What is different?

  7. Warmup: 9/11 What are the 5 characteristics of life that your textbook uses? Use that checklist to determine whether the following are biotic (living) or abiotic (nonliving). One has been done as an example:

  8. Characteristics of Life:

  9. 1. Respond to Stimuli in Their Environment • Stimuli- factors in the environment that living things react to Examples: Light, temperature, sound, and more.

  10. 2. Grow and Develop • Cells divides to make new cells during cell division & this results in growth. • Some cells become specialized and perform different jobs (differentiation).

  11. 3. All Living Things Reproduce • Sexual - two sex cells required • Asexual - only one parent cell is needed

  12. 4. Need Energy to Survive • Autotrophs - get energy from sun • Heterotrophs - get energy by consuming nutrients from their environment

  13. 5. Composed of Cells • Unicellular (one cell) • Single-cell organisms have everything they need to be self-sufficient - example: bacteria • Multicellular (many cells) • Many-cell organisms have specialization. - example:animals, plants
