Biology

1. Biology Ecosystems

2. Content Standard 4.2 Organisms cooperate and compete in ecosystems

3. Ecology

4. Ecology The study of ecosystems

5. Ecosystems include all the interacting parts of the environment in an area.

6. Interactions in ecosystems - 5 min

7. A niche is the sum total of an organism's use of biotic and abiotic resources in the environment, how it "fits into" an ecosystem.

8. A number of different animals can live in the same biome because each occupies its own special space, or niche.

9. A niche may apply to species, populations, or even individuals

10. Species cannot coexist in a community if their niches are identical.

12. After years of searching Walter finally found his niche.

13. Habitat The physical area in which an organism lives.

14. Niche The way of life of an organism.

15. Prey Predator Predator's predator Predation

16. Prey Predator Predator's predator Refers to the relationship between a predator and prey. Predation

17. Prey Predator Predator's predator In other words, one organism using another for food. Predation

18. Predation - 9 min

19. Carnivores eat only meat Herbivores Omnivores eat only plants eat plants and meat

21. Food Chain: The specific sequence in which organisms obtain energy within an ecosystem.

22. Primary Consumers Also called herbivores, eat only plants.

23. Secondary Consumers Also called carnivores, eat only animals.

24. Tertiary Consumers eat secondary consumers.

25. Food Web

26. Food Web Interrelated food chains within an ecosystem.

28. Why don't humans eat carnivores?

29. Kingfisher Trout Insect Larvae Algae Food Pyramid

30. Indicates the trophic levels within an ecosystem Kingfisher Trout Insect Larvae Algae Food Pyramid

31. Trophic is a word associated with energy. Kingfisher Trout Insect Larvae Algae Food Pyramid

32. Kingfisher Trout Insect Larvae Producers 100% Algae

33. All producers are able to make their own food through photosynthesis. Kingfisher Trout Insect Larvae Producers 100% Algae

34. Food stored by producers is ALL the food energy available in the food chain. Kingfisher Trout Insect Larvae Producers 100% Algae

35. Kingfisher Trout Primary Consumers 10% Insect Larvae Producers 100% Algae

36. Primary consumers feed on producers. Kingfisher Trout Primary Consumers 10% Insect Larvae Producers 100% Algae

37. Primary consumers use 90% of their food energy to stay alive. Kingfisher Trout Primary Consumers 10% Insect Larvae Producers 100% Algae

38. Kingfisher Secondary Consumers 1% Trout Primary Consumers 10% Insect Larvae Producers 100% Algae

39. Secondary consumers feed on primary consumers Kingfisher Secondary Consumers 1% Trout Primary Consumers 10% Insect Larvae Producers 100% Algae

40. Tertiary Consumers 0.1% Kingfisher Secondary Consumers 1% Trout Primary Consumers 10% Insect Larvae Producers 100% Algae

41. Tertiary Consumers 0.1% Kingfisher Only 10% of the energy in one trophic level is available as food for the next higher level. Secondary Consumers 1% Trout Primary Consumers 10% Insect Larvae Producers 100% Algae

42. ALL food chains, food webs, and food pyramids begin with producers. Algae

43. A normal food pyramid looks like this.

44. Give me an example of how the pyramid could look like this.

46. Protective Coloration

47. Allows an organism to blend with the environment. Protective Coloration

48. A prey animal looks like a dangerous, or bad tasting, animal. Mimicry

49. Which one is poisonous? Mimicry

50. Coral Snake Scarlet Kingsnake Red on black is friend of Jack. Red on yellow will kill a fellow. Mimicry
