1. ECOLOGY
THE STUDY OF HOW ORGANISMS INTERACT WITH EACH OTHER AND WITH THEIR ENVIRONMENT.

2. ENVIRONMENT ORGANIZATION
INDIVIDUAL – 1 ORGANISM OF A SPECIES
POPULATION- ALL OF THE ORGANISMS OF THE SAME SPECIES THAT LIVE IN THE SAME AREA.
COMMUNITY- ALL OF THE POPULATIONS THAT LIVE IN THE SAME AREA.
ECOSYSTEM- ALL OF THE LIVING ORGANISMS AND NON LIVING FACTORS IN THE SAME AREA.
BIOME- A LARGE REGION THAT HAS A DISTINCT CLIMATE AND SPECIFIC TYPES OF PLANT AND ANIMAL LIFE
BIOSPHERE- THE PART OF EARTH THAT SUPPORTS LIFE

4. BIOTIC FACTORS- The living or once living factors in an ecosystem.
human, hawk, plants, fish, turtle, bacteria, algea

5. ABIOTIC FACTORS- All of the nonliving
factors in an ecosystem.
land, water, air, temperature

6. HABITAT- The place an organism lives.

7. NICHE- The role/job an organism has in its ecosystem.

8. FEEDING RELATIONSHIPS
Most energy that moves through an ecosystem starts with the sun.

9. PHOTOSYNTHESIS- Chemical
process by which plants use light
energy to make sugar from water
and carbon dioxide.

12. PRODUCERS- can make their own
food

13. HERBIVORES (CONSUMERS)-
obtain energy by eating plants

14. CARNIVORES (CONSUMERS)-
obtain energy by eating other
animals (they eat meat)

15. SCAVENGERS (CONSUMERS)-
obtain energy by eating the dead
remains of animals

16. OMNIVORES (CONSUMERS)-
obtain energy by eating both plants
and animals

17. DECOMPOSERS- Organisms that
feed on dead matter and breaks them down into nutrients that are returned to the soil

18. FOOD CHAIN- traces the path of
energy as it moves from one
organism to the next in an
ecosystem

19. FOOD WEB- several overlapping
food chains

20. RELATIONSHIPS BETWEEN DIFFERENT SPECIES
COMPETITION- occurs when organisms compete for the same resource
PREDATION- feeding relationship where one organism captures, kills, and eats another organism
SYMBIOSIS- a close relationship between two species

21. COMPETITION

22. PREDATION

23. SYMBIOSIS

24. MUTUALISM- both species benefit

25. l
COMMENSALISM- one species
benefits and the other is unaffected

26. PARASITISM- one species benefits
and the other is harmed
