Presentation Transcript

  1. Ecology Biological Communities and Interactions

  2. Ecology: the relationships between living things and their environment. • Terms to Know: • Biotic – all living organisms • Abiotic– all non-living things (air, water, light, rocks, soil,…) • (a - means without; bio - means life)

  3. Biotic

  4. Abiotic

  5. ABIOTIC

  6. ABIOTIC

  7. ABIOTIC

  8. Organization of Living Things (Biotic) Species – group of organisms able to Interbreed, under natural conditions, and produce fertile offspring. A liger (cross btwn. A tiger and lion in a zoo is not natural condition. A donkey bred with a horse makes a Mule –which is sterile. Fertile: can reproduce Sterile: cannot reproduce

  9. Organization of Living Things (Biotic) continued… • Population – group of 1 species living in the same place at the same time. • Community – several populations that interact with each other. • Ecosystem – all of the populations in the community and the environment (abiotic) . • Can be Aquatic – in water • Or Terrestrial – on land

  10. Organization of Living Things (Biotic)Continued… Biosphere: The layer of the earth where life exists (includes the soil and into the atmosphere) Other Ecology Terms to Know: Habitat : where an organism lives Niche : what an organism does to survive/it’s job in the ecosystem.

  11. Species (Organism) Population Community Ecosystem Biosphere

  12. Species Interactions SYMBIOSIS – A close relationship btwn 2 species in which one or both depend on the other. TYPES OF SYMBIOSIS Mutualism Commensalism Parasitism Competition Predator-Prey

  13. MUTUALISM - both species benefit.

  14. MUTUALISM – Clown fish and anemone

  15. MUTUALISM Clown fish and anemone

  16. MUTUALISM – ants and acacia tree

  17. MUTUALISM – flower and bee

  18. MUTUALISM – crocodile and bird

  19. MUTUALISM – shrimp and eel

  20. MUTUALISM – ray and remora

  21. MUTUALISM – Remora’s Head

  22. COMMENSALISM – one species benefits, the other is not affected. Spanish moss on an oak tree.

  23. COMMENSALISM – birds and Trees

  24. PARASITISM – One species benefits, the other species is harmed. Tick sucks blood of animals

  25. PARASITISM – Hook Worm

  26. PARASITISM - Hook worm in a foot

  27. PARASITISM- Mistletoe

  28. Mistletoe

  29. COMPETITION – organisms who need the same resources (food, habitat, mates,…)

  30. o Competing Kangaroos

  31. Predator – Prey – organism kills another for food.

  32. Predator-Prey
