1. Ecology
Scientific study of interactions between organisms and their environment.

2. Interdependence An organisms ability to interact with their :
Non-living environment
Other organisms
Survival depends on these interactions

3. Interdependence 6

4. Levels of Organization
Biosphere
Biome
Ecosystem
Community
The study of ecology ranges from the study of an individual organism to populations, communities, ecosystems, biomes—and, finally, to the entire biosphere. The information that ecologists gain at each level contributes to our understanding of natural systems.
Population
Individual

5. Organism/Individual/Species
An individual/species can breed and produce fertile offspring

Population
A group of organisms, (same species), which live in the same place at the same time.

7. copyright cmassengale
Community
All the populations of different species that live in the same place at the same time.

8. Ecosystem (Living and Nonliving)
ALL the organisms and non-living environment found in a particular place

Biomes are
groups of ecosystems that have similar climate & communities

The Biosphere
Life is found in air, on land, and in fresh and salt water.
The BIOSPHERE is the portion of Earth that supports living things.

11. Animal Interactions

12. What shapes an ecosystem?
Biotic Factors
All of the living things in an environment.
Plants, Animals, bacteria, etc.
Abiotic Factors- non living things in the environment.
Climate
Wind
Nutrient Availability
Sunlight

13. Sunlight is the main source of energy for life on Earth

14. Energy Transfer Producers/Autotrophs Consumers/Heterotrophs
These are organisms that must eat other organisms for food/energy.
These are organisms that use sunlight to make their own food/carbs

15. Producer (autorotroph) or consumer (heterotroph)?

16. 5 types of heterotrophs 1. Herbivore 2. Carnivore -eats animals
eats plants
Cow eating grass
2. Carnivore
-eats animals
Lion eating a zebra

17. Bears mainly eat berries and fish
4. Decomposer
breaks down organic matter-NO MOUTH
Mushrooms are decomposers
3. Omnivore
-eats plants and animals
Bears mainly eat berries and fish

18. feeds on plant and animal remains (Detrivore) (HAS A MOUTH)
Crab
5. Detritivore
feeds on plant and animal remains (Detrivore) (HAS A MOUTH)
Earthworms
Mite
Snail

19. Food Chain Video

20. Super awesome high tech ecology animation

21. Sun light energy is converted by plants into useable carbohydrate energy, and stored in the plant
Carb energy is transferred to the wolf as it eats the fox
Fox remains recycled into soil by decomposers (bacteria) who eat the carcus
Carb energy is transferred to the fox when it eats the rabbit
Carb energy is transferred to the rabbit when it eats the plant

22. Energy flow in an Ecosystem
Energy flows through an ecosystem in
one direction, from the
sun autotrophs heterotrophs
Last slide I talked about with period 1 22

23. Food chains show how energy flows from one organism to the next.
Each level in the food chain is called a trophic level.
Terrestrial ecosystems usually have 3 or 4 levels. 23

24. Food Chains Given these organisms create a food chain GRASSHOPPER
SNAKE

25. Honors food chain Producer Primary Consumer Seconday Consumer
Tertiary Consumer
Quaterny Consumer

26. Make your own With your team, make your own food chain
Start with a producer, then primary consumer, secondary consumer, tertiary consumer.

27. Food Web
This links all of the food chains in an ecosystem together

A food web links all the food chains in an ecosystem together
