1. Ecosystem Organization

2. Ecology
The study of the relationship between populations and the environment.

4. Organism
Organism = an individual living thing

5. Population
All individuals of one SPECIES that live in the same area at a given time

6. Community
All the populations that live in an ecosystem. This includes all plants, animals, fungi, bacteria, etc.

7. Ecosystem
All the living and nonliving parts of an environment (community & environment)

8. Biotic Factors of an Ecosystem
Biotic = features of the environment that are alive or were once living.
Examples:
Bacteria
Mushroom
Hawk
Grass

9. Abiotic Factors of an Ecosystem
Abiotic = nonliving physical features of the ecosystem
Examples:
Climate (typical weather in an area from season to season)
Air, Water, Sunlight, Soil, Temperature

10. What makes up an ecosystem?

11. Check for understanding!
Ecosystem Organization

12. Label the diagram below using the words: Ecosystem Individual Organism Community Population

13. Study the picture below and list 3 biotic factors & 3 abiotic factors in this ecosystem

14. Carrying Capacity
The largest number of individuals of a particular species that an ecosystem can support overtime.

15. Interdependence is a Balance
Ecosystems will fail if they do not remain in balance.
A balanced ecosystem is the result of interactions between the community and environment
No community can carry more organisms than its food, water and
shelter can accommodate.

16. Limiting Factors
Anything that restricts or limits the size of a population, including the living and nonliving features.

17. More Examples of Limiting Factors
Lack of resources like food, water, space
Predation
Climate
Habitat Destruction
All of these limit the growth of certain populations in the ecosystem.
