1. Ecology/ populations & succession

2. Bell work What is an ecosystems?
What things are included in an ecosystem?
Are there living and non living things in an ecosystem?
Bell work

3. This Chapters Big Ideas
Ecology is the study of interacting ecosystems
Ecosystems have living and nonliving parts.
All living things are organized into groups.
Energy moves within ecosystems.

4. What is an ecosystem?
Ecosystem: is made up of organisms interacting with one another and with nonliving factors to form a working unit.

5. What is an ecosystem?
Ecology: is the study of interactions that take place among living and nonliving parts of an ecosystem.

6. What is an ecosystem?
Biosphere: is the part of Earth where organisms can live.
Includes the top layer of Earth’s crust, oceans, rivers, and lakes, as well as the surrounding atmosphere.

7. What is an ecosystem? Biotic vs. Abiotic factors Abiotic Biotic
All living things in the ecosystem
Abiotic
All nonliving things in the ecosystem
Ex: soil, temperature, water, sunlight
Biotic vs. Abiotic factors

9. What is an ecosystem?
Every ecosystem is made up of many biotic and abiotic factors working together.
These factors can be balanced or off balanced
Exit Card:
What could cause an ecosystem to be off balance??

11. Section2: Relationships among living things
Bell work: compare and contrast biotic and abiotic factors.

12. Relationships among living things
Studying the entire biosphere would be a huge job!! So scientists split up the biosphere into smaller groups in order to study. They then see how these smaller groups interact together.

13. Relationships among living things
Population: is a group of the same type of organisms living in the same place at the same time.
Example: the different fish species that live in a coral reef is considered a population

14. Relationships among living things
All of the populations that live in an area make up a community.
Example: The fish, mollusks, echinoderms, and cnidarian in the reef make up a community.

15. Relationship among living things
Identify three populations in this picture below:

16. Is this a Population or community?

17. Identify two populations below…

18. Relationships among living things
Population density: compares the size of the population with its area.

19. Relationships among living things
Can a population grow larger and larger forever???

20. Relationship among living things
NO!!!
Limiting factors: Factors stop a population from growing
Examples: Water, food, & shelter.

21. Relationships among living things
Our human population in 5 minutes.

22. Relationships among living things
A small treat… maybe too small ;)
Competition

23. Relationships among living things
Competition: happens when a resource can not supply a whole population
This can happen with food, water, shelter, and sunlight.

24. Symbiotic Relationships
Symbiosis: any close relationship between species of animals/plants
Mutualism: both species benefit
Commensalism: one organism benefit and the other is not helped or harmed
Parasitism: one organism benefits, the other is harmed and may even die.

25. Relationships among living things
Niche: The role of an organism in an ecosystem
What is a frogs niche in a pond ecosystem?
What is a plants niche in the pond ecosystem?
What is your niche today in this class?

26. Relationships among living things
Habitat: the place where an organism lives.
Where is a polar bears habitat?
Where is a whales habitat?
Where is your habitat?

28. Energy through the ecosystem
Energy moves through an ecosystem in the form of food!!
Lets take a look at how this happens…

29. Energy through the ecosystem
Producers vs. Consumers
Producers
An organism that makes its own food
plants
Consumers
Eats other organisms for energy
Animals

30. Energy through the ecosystem
So… what is a decomposer??

31. Energy through the ecosystem
Modeling the flow of energy:
We can show the flow of energy through a food chain or a food web !!

34. Intro to Succession
Ecological succession is the observed process of change in the species structure of an ecological community over time.
Licking Heights intro task

35. Primary Succession
The first batches of organisms that establish themselves in that environment are called primary colonizers, primary community, or simply pioneers.
Primary succession occurs where the area is totally devoid of vegetation such as places devastated by volcanic activity or glaciations.
Typical examples of primary succession are species such as lichens and algae. They form the base line for other species to sprout up and grow in the area.

36. Secondary Succession
This type of succession is forced because the previous population was wiped out due to factors such as sudden steep changes in the climate such as a flood or drought or biotic interventions such as concreting or fire.
Due to these factors the area lost the living matter, but the substratum has been modified to sustain living matter and thus the next population developing there is called a secondary succession.
