1. What is Ecology
The study of the interactions among living things and their environment

2. Where on Earth does life exist?
Life exists in the biosphere.

3. The levels of Organization in the Biosphere
Biome
Ecosystem
Community
Population
Species

4. Biosphere Biome Ecosystem Community Part of Earth where life exits
Population
Species
Part of Earth where life exits
Ecosystems with the same
climate and communities
Let
me break it
Down!
All living and nonliving factors in a
particular environment
Group of different species that live
together in one area
A group of the same species living in
one area
An organism, an individual
Good job
my friend!

5. Biomes
A biome is a large ecosystem characterized by a distinctive type of vegetation and maintained under the climatic conditions of the region. Biomes can be either terrestrial or aquatic.

6. Biomes Terrestrial Aquatic Freshwater Tundra Marine Water
Estuaries
Tundra
Northern Coniferous Forest
Deciduous Forest
Grasslands
Deserts
Tropical Forests
Shrub Lands

7. Tundra Few plant species survive the cold, severe climate
Permafrost: ground below the surface is always frozen

8. Georgia Lake Ecosystem
Biosphere
Biome: Deciduous Forest
Ecosystem: trees, animals, rocks, air, water, soil, etc..
Community: Georgia Lake
Population: fish
Species: Trout FIsh

10. Levels of Organization Illustration
Create/Illustrate the levels of organization in a marine aquatic environment or the tropical rainforest.
Include: biosphere, biome, ecosystem, community, population, species
Have fun !!!

11. Ecology All ecosystems are made of living and nonliving things.
Biotic Factors: living things such as plants, animals, fungi, and bacteria
Abiotic Factors: nonliving things such as wind, air, soil, and rocks
Think of the rainforest biome and list 5 biotic factors and 5 abiotic factors of this biome.

12. Take a Moment and Think What is biodiversity?
Explain keystone species.
Variety of living things in an
Ecosystem
A species that has a large effect
on an ecosystem

14. All organisms in an ecosystem must have a source of energy in order to survive.
Producer/Autotroph: organisms that use the energy from the sun through photosynthesis or utilize chemosynthesis to make their own food.
Consumer/Heterotroph: organisms that consume other organisms for their food source.

15. There are 5 types of Consumers/Heterotrophs
Get with a friend and think of 2 examples for each type of consumer.
Herbivores: eat only plants
Carnivores: eat other animals
Omnivores: eat both plants and animals
Detrivores: eat detritus (dead organic matter)
Decomposers: detrivores that break down dead organic matter into simpler compounds

16. Food Chain and Food Web
Food chains and food webs show the feeding relationships and movement of energy from organism to organism.

17. Food Chain
Food Chain: a series of steps in which organisms transfer energy by eating and being eaten.
Take a Moment : Using the following organisms, create a simple food chain. Remember the arrow points to the belly the organism goes in.
Rabbit
Sun
Hawk
Bacteria
Grass

18. Each level in a food chain is referred to as a trophic level.

19. Food Web
Food Web: a complex network of feeding relationships.

20. Symbiotic Relationships
Mutualism: both species benefit
Commensalism: one species benefits and the
other is neither harmed nor benefited
Parasitism: one species benefits and the other is
harmed
