4. Levels of Organization
1. ORGANISM
One individual from a population
Example: alligator

5. Levels of Organization
2. POPULATION
Group of individuals of the same species that live together
Example: alligators living in the same area

6. Levels of Organization
3. COMMUNITY
All the populations of species that live in the same habitat and interact with each other
Example: Population of alligators and all the species they interact with.

7. Levels of Organization
4. ECOSYSTEM
Community of organisms and their abiotic environment
Example: the swamp where the alligators live

Ecologist divide environment factors that influence organisms into two groups:
ABIOTIC

Producers

24. Living things need energy!
How do we get energy?
How do plants get energy?
Organisms in a community can be divided into three groups:
- Producers
- Consumers
- Decomposers

25. PRODUCERS
Producers – organisms that use sunlight directly to make food (photosynthesis)
Examples – plants, algae, GREEN
What does produce mean?

26. CONSUMERS
Consumers – organisms that eat other organisms to get their energy.
What does consume mean?

27. Types of Consumers Herbivore – an animal that eats only plants
Examples: grasshopper, prairie dogs, and bison
Carnivore – an animal that eats other animals
Examples: coyotes, hawks, owls
Omnivore – an animal that eats plants and animals
Examples: mice, bears, humans

28. DECOMPOSERS
Decomposers- organisms that get energy by breaking down dead organisms
Examples – worms, fungi, and bacteria

Decreasing energy for higher consumers
Large amounts of producers are needed
Only 10% of energy is passed from level to level, 90% is wasted!

40. Bellwork 3/2 page 68 – Food Chain vs. Food Web

41. Food Chain
Food chain – a diagram that shows one path of energy flowing from one organism to another

42. Food Web
Food web- shows multiple paths of the feeding relationship between organisms in an ecosystem

46. You have 10 minutes at the beginning of class to work on the tasks from yesterday! Everyone start with Task 2. If you have that done, work on any others that are incomplete.

47. Types of Interactions – pg. 69

48. With your group use prior knowledge…
Discuss the meaning of the following terms:
MUTUAL
PARASITE
ADAPT
COMMENSAL

49. SYMBIOISIS
Relationship with two different organisms living in close association with each other
There are three kinds:
- mutualism
- commensalism
- parasitism

50. MUTUALISM
Relationship where both species benefit

51. ADAPTATION
Changes in behavior and structure of an organism to become more suited to an environment

52. PARASITISM
Relationship where one organism benefits and the other (the host) is harmed.

53. PREDATOR
Organism that eats all or part of another organism

54. COMMENSALISM
Relationship where one benefits and the other is unaffected.

55. PREY
Organism that is killed and eaten by predator

65. Honey guide birds alert and direct badgers to bee hives
Honey guide birds alert and direct badgers to bee hives. The badgers then expose the hives and feed on the honey first. Then the honey guide birds eat. 2

68. Ostriches and gazelles feed next to each other
Ostriches and gazelles feed next to each other. They both watch for predators and alert each other to danger. Since the visual abilities of the two species are different, they each can identify threats the other animal would not as readily see. 5

Yucca flowers are pollinated by yucca moths. The moths lay their eggs in the flowers where the larvae hatch and eat some of the developing seeds. Both species benefit. 13
