  1. Biotic andAbioticThings

  2. Objectives • Differentiate living and non-living things • Discuss the characteristics of living things

  3. What are living things? • The things we see around can be divided into two groups. • Biotic and Abiotic • Click each tab to view what living things and non-living things are.

  4. What are living things? • The things we see around can be divided into two. Living and non-living things. • Click each tab to learn what living things and non-living things are. Non-living things can be divided into two. The things that were once a part of a living thing. For example: coal, paper The things that were never a part of a living thing. For example: stones, water, air

  5. What are living things? • The things we see around can be divided into two. Living and non-living things. • Click each tab to learn what living things and non-living things are. Characteristics of living things include growth and development, reproduction, movement, response to stimulus, and metabolism.

  6. Cells • All living things are made of cells. • Unicellular – one cell • Multicellular – many cells • Levels of Organization: • atoms, molecules, cell, tissue, organ, system, organism, population, community, ecosystem, biome, biosphere

  7. Characteristics • The characteristics of living things are: • Movement • Metabolism • Growth and Development • Response to Stimulus • Reproduction • Click each characteristic to learn more.

  8. Characteristics • The characteristics of living things are: • Movement • Metabolism • Growth and Development • Response to Stimulus • Reproduction • Click each characteristic to learn more. All living things have the ability move. The movement can be internal or external.

  9. Characteristics • The characteristics of living things are: • Movement • Metabolism • Growth and Development • Response to Stimulus • Reproduction • Click each characteristic to learn more. The ability to undergo chemical reactions to convert food into energy.

  10. Characteristics • The characteristics of living things are: • Movement • Metabolism • Growth and Development • Response to Stimulus • Reproduction • Click each characteristic to learn more. • Growth means becoming larger and complicated. • Life span • Life expectancy • Life cycle

  11. Life span – how long an organism lives • Life expectancy – the average length of time within a population • Life cycle - the complete succession of changes undergone by an organism during its life

  12. Characteristics • The characteristics of living things are: • Movement • Metabolism • Growth and Development • Response to Stimulus • Reproduction • Click each characteristic to learn more. Living things react to touch, light, heat, cold, and sound. Changes (stimulus) cause an organism to react (response).

  13. Response to Stimuli • Tropism – a plant’s growth response toward to away from a stimulus. • Geotropism, phototropism, thigmotropism, hydrotropism • Adaptations – in response to their environment, species evolve, or change over time.

  14. Characteristics • The characteristics of living things are: • Movement • Metabolism • Growth and Development • Response to Stimulus • Reproduction • Click each characteristic to learn more. Reproduction is the process of creating a new organism like itself.

  15. Reproduction • Asexual – One cell can split into two to make a new organism • Sexual – Two cells share DNA to make a new organism

  16. Population All members of one species in a particular area. A species is a group of individuals that can reproduce offspring.

  17. Community All the different organisms that live together in an area and interact. Within a community, there are many populations.

  18. Ecosystem All the biotic and abiotic things that working together as a functional unit.  Ecosystems will fail if they do not remain in balance. Within an ecosystem, there are many habitats.

  19. Biome Large regions of the world with similar plants, animals, and other living things that are adapted to the climate. It is made up of similar ecosystems.

  20. Biosphere All the environments on earth that are inhabited by life. People that study how living things interact with one another and with their environment is called ecology.
