1. Living things and the environment
1.1
Living things and the environment

2. Activity (teacher prints individual nature picture)
Look at the picture
Use colored pencil to draw arrows to living things and name them
Use colored pencil to draw arrows to non-living things and name them
Class discussion:
How do living things in picture depend on non-living things????

3. WHAT is HABITAT?
Habitat - is an environment that provides the things (food, water, home) for an organism to live, grow and reproduce.

4. Habitat Different organisms live in different habitats
Why? Because different organisms have different needs
For example, snakes like hot temperature, so they like deserts

5. Match the organism to its habitat

6. Environment Abiotic factor: Biotic factor: living non-living things
(ex. rocks, soil,
water)
Biotic factor: living
things (ex. horse,
worm, trees)

7. BIOTIC FACTORS page 7
Other examples of biotic factors:

8. Abiotic FACTORS

9. WATER

10. SUNLIGHT

11. OXYGEN

12. TEMPERATURE

13. SOIL

14. LEVELS of ORGANIZATION
Organism
Populations
Communities
Ecosystems

16. WHAT IS AN ORGANISM?
Organism – is an single living thing.

17. What is POPULATION?
Population- is all the members of the same animals or plants that are in a specific area.

18. What is SPECIES?
Species - is a group of organisms that are similar and can mate with each other and produce viable offspring (is a part of population).

19. WHAT IS COMMUNITY?
Community – is all the different populations that live together in an area

20. WHAT IS ECOSYSTEM?
Ecosystem- is an area in which living and non-living parts interact with each other.

21. LEVEL OF ORGANIZATION- review
Organism (a single living thing)
Population
Community
Ecosystem

22. WHAT IS ECOLOGY????
Ecology- is the study of how living things interact with each other and with the environment (a part of science).

23. SCIENCE
Biology
Chemistry
Physics
Astronomy
Ecology

24. Review: matching
Organism __how living things interact with their environment
Habitat __different populations living together
Biotic factor __can breed with each other. Similar to each other
Abiotic factor __non-living thing, i.e. rocks
Photosynthesis __home, where species live
Species __animals or plants, i.e. tiger
Population __living thing, i.e. fish
Community __plants make food using the sun
Ecosystem __same species living together
Ecology __place where organisms live, i.e. desert

25. REVIEW 1.1: What is habitat?

26. Why do different organisms live in different habitats?

27. How do abiotic factors differ from biotic factors?

28. What are levels of organization?

29. What is community?

30. Assessment 1 page 10
1a. What basic needs are provided by an organism’s habitat? 1b. What might happen to an organism if its habitat could not meet one of its needs? 2a. Define the terms biotic and abiotic factors. 3b. List all the biotic and abiotic factors in Figure 4.

31. Assessment 1 page 10
2c. Explain why water and sunlight are two abiotic factors that are important to most organisms. 3a. List these terms in order from the smallest level to the largest: population, organism, ecosystem, community. 3b. Would all the different kinds of organisms in a forest be considered a population or a community? Explain. 3c. How might a change in one population affect other populations in a community?
