3. I. Habitats A. An organism is a living thing.

Animal Habitats (8:01)

4. I. Habitats
C. An environment that provides the things the organism needs to live, grow and reproduce is its habitat.
D. One area may have many habitats.
E. Why do different organisms live in different habitats? Different kinds of organisms have different needs. Their habitats must meet those needs for live.

5. II. Biotic Factors
A. An organism interacts with both the living and nonliving parts of its habitat.
B. The living parts of a habitat are Biotic factors.
C. Name a biotic factor in your habitat.
People
Plants
Animals

6. III. Abiotic Factors
A. Abiotic factors are the nonliving parts of an organism’s habitat.

7. III. Abiotic Factors B. Abiotic Factors include:
1. WATER all living things need water to carry out their life processes.
2. Water is required for the process of photosynthesis.

8. III. Abiotic Factors B. Abiotic Factors include:
3. Most living things require Oxygen to carry out their living processes.

9. III. Abiotic Factors B. Abiotic Factors include:
4. The temperatures that are typical of an area determine the types of organisms that can live there.
Frozen, No Heat Experience (1:04)

10. III. Abiotic Factors B. Abiotic Factors include:
5. Soil is a mixture of rock fragments, nutrients, air, water and decaying material.

11. III. Abiotic Factors
C. How do Abiotic Factors differ from Biotic Factors?
Biotic factors are living and Abiotic factors are nonliving.
Living = Plants and Animals
Nonliving = Water, Sunlight, Oxygen, Temperature and Soil

12. IV. Levels of Organization
A. Organism is the smallest level of organization.
1. A species is a group of
organisms that are physically
similar, can mate with each
other and produce offspring
that can mate and reproduce.

13. IV. Levels of Organization
B. All the members of one species in a particular area are a Population.
Mr. Parr Ecosystem Song (3:27)

14. IV. Levels of Organization
C. All the different populations that live together in an area are a Community.

15. IV. Levels of Organization
D. The community of organisms that live together in a particular area, along with the nonliving surroundings, make up an Ecosystem.
E. What is Ecology?
It is the study of how
Living things interact with
each other and their
Environment.
