5. Ecology Inquiry
In your notes, make a list of all the types of organisms, including plants, humans, insects that you have seen near our school.
How do these organisms interact with one another?
Do any of the organisms provide energy/nutrients to one another?
We are going to start today with an ecology inquiry. At the top of your notes is a box. In this box I want you to make a list of all the types of organisms including plants, humans, insects that you see by your home or your school. After you make a list of the plants answer question #2. How do the organisms you listed interact with one another? Do any of the organisms you listed provide energy? Keep this list in mind as we start our ecology unit this week and as we discuss the definition of ecology today.

6. Ecology
Key Point #1: _____________is the study of interactions between organisms and their environment.
ECOLOGY
Ecology
How would this forest fire impact the environment and organisms? The fire ruins home for animals and changes the environment. There are less trees and bushes now.

7. For ecologists to study the earth, they organize the earth into smaller units.

9. THE BIOSPHERE The Biosphere:
Part of the earth that is capable of supporting life

11. Let’s Start at the Bottom…
Organism:
Any one thing that is living
Example: an elephant
Every organism has a job in its ecosystem, this job is called a _________
Niche: to eat shrubs and fruits
niche
NICHE

13. Population Population: Same type of organism living in the same place
Example: In the savanna, a herd of 20 elephants would make up one population

15. Communities Communities: Different populations living together
Example: In the savanna, populations of elephants, lions, and zebras live and interact to form a community

17. Ecosystem Ecosystem: All the ecosystems in a bigger geographic
Therefore, all the COMMUNITIES AND THE ABIOTIC FACTORS in a certain place make up an ecosystem
Ecosystem:
A community of living organisms interacting with their environment
biotic and abiotic
All the ecosystems

location makes up a biome
Biotic and abiotic

Examples?
Abiotic factors
non-living
Example?
Introduce ecosystem. Biotic and abiotic factors working together

19. How do the biotic and abiotic factors depend on one another?
Turn and Talk
How do the biotic and abiotic factors depend on one another?

Have students turn and talk with a classmate about the answer to this question. When they are finished, be ready to share out.

20. Abiotic and Biotic Interactions
The purple arrows indicate the heat energy released at each stage. The flow of energy can also mean work being done and nutrients that give us energy.
The First Law of Thermodynamics states that energy (or matter) cannot be created or destroyed, but can only change forms. Students know it’s restatement as “The Law of Conservation of Energy” and/or “The Law of Conservation of Matter”.
Point out to students that each and every time energy or matter “changes form” energy is invariably conserved but the internal energy of a closed system changes as heat and work are transferred in or out of it. (Closed systems are rare in biology!)
The entropy of any isolated system not in thermal equilibrium almost always increases. “Chaos happens”.
The Second Law of Thermodynamics states that in all energy transformations entropy occurs (we usually refer to this as heat in biology).
The cycles listed on the Abiotic side of the diagram refer to all of the cycles of matter on Earth- Rock cycle, phosphorus cycle, water cycle, carbon cycle, etc.). Another important Physics law that pertains to ecology is the Conservation of Matter (also called the Conservation of Mass), which states that matter cannot be created or destroyed. Anytime we use the word conservation we imply a mathematical relationship. What you put in on the left side of an equation must all be accounted for on the right side of the equation.
These two principals are important to understand since anytime you transform energy or change matter, you have to account for everything that went into the process and that must equal everything that came out of the process (even if some of the products are degraded forms such as entropy or heat).
It may help students so see the mathematical expression of entropy which is symbolized by “S”; 𝑆= 𝑞 𝑇 where q = quantity of heat (in Joules, thus an energy) and T is the temperature in Kelvins.

22. What is a biome?
Biome:
A geographical region with distinctive types of plants, animals, and climate
Example: tropical rain forest, savanna, and grasslands
Sometimes people use the words “ecosystem” and “biome” interchangeably - However, technically an ecosystem can be much smaller than a biome, for example it can be as small as a puddle!
We are going to start really big with a Biome. A biome is a large region that has distinctive climate and plants.

23. Key Point #3: Biomes are made up of biotic and abiotic factors.
