Presentation Transcript
1. ECOLOGY The study of interactions of organisms and their environment
2. Levels of Organization • Individual Organisms (Species) • Populations • Communities • Ecosystems • Biosphere
3. Organisms/Species • A human ( Homo sapien ) • Deer • Piranaha • Worm • Bigfoot?
4. Populations • Same species living in same area • Species? -can breed and produce offspring that can have babies
5. Communities • Coral Reef • Cedar swamp • Vernal pool
6. Ecosystems • Tropical rainforest • Desert • Temperate deciduous forest (ours) • Ponds • Coral reef
7. Biosphere
8. Physical Conditions ABIOTIC - non-living • Sunlight • Water • Temperature • Soil • Wind • Disturbance BIOTIC - living things • Bacteria • Protists • Fungus • Plants • Animals
9. PRODUCER - an organism that makes its own food (autotroph) - becomes food for other organisms.
10. CONSUMER - organism that obtains food by eating others (producers or other consumers)
11. DECOMPOSER - organism that breaks down wastes and dead organisms
12. HERBIVORE - consumer that eats only producers.
13. OMNIVORE - consumer that eats both producers and consumers (plants, fungi, and meat)
14. CARNIVORE - consumer that eats only other consumers (exclusively meat-eaters)
15. FOOD CHAIN - pathway of food transfer from one trophic level to another.
16. FOOD WEB -pattern of feeding in an ecosystem consisting of interconnected and branching food chains
17. Energy Pyramid
18. Primary Succession • The development of brand new land – (volcano created new land)
19. Secondary Succession • A once established forest is destroyed and has to start growth over. For example a forest fire
20. Mutualism • Both species benefit
21. Commensalism • One species benefits the other gets nothing
22. Parasitism • One species harms another • Think parasite
23. Predation • Predator Prey – One eats the other
