Ecology - Negative Interaction - PREDATION (KMB)

Predation - The interaction between two species in which one specie, the predator, feeds on the other specie, the prey.

1. Negative Interaction: PREDATION

2. P PREDATION PREDATOR P PREY

3. Predation The interaction between two species in which one specie, the predator , feeds on the other specie, the prey .

4. Predator and prey relationships

5. A predator is an organism that eats another organism.  The prey is the organism which the predator eats. 

6. lion and zebra

7. bear and fish

8. fox and rabbit

9. Bear and berry

10. rabbit and lettuce

11. grasshopper and leaf

12. Predation , in the broadest sense, describes interactions that have a positive influence on one species, and a negative influence on the other species.

13. Predation theory when prey are numerous their predators increase in numbers, reducing the prey population, which in turn causes predator number to decline.

14. Predator-prey population dynamics

15. Predators kill prey  affects prey death rate prey population size depends on number of predators with few predators, prey population grows with many predators, prey population shrinks Predator-prey population dynamics are connected

16. Predators eat prey  affects predator birth rate predator population size depends on number of prey with many prey, predator population grows with few prey, predator population shrinks Predator-prey population dynamics are connected

17. Predators kill and eat prey  affects prey death rate  affects predator birth rate with few predators , prey population with many prey, predator population with many predators, prey population with few prey, predator population Predator-prey population dynamics are connected grows grows shrinks shrinks

18. Prey numbers increase, predator numbers increase…

19. 5 T y p e s O f Predation

20. 5 TYPES OF PREDATION

21. Herbivores Animals that prey on green plants, seeds or fruits

22. Carnivores Typical predation , where one animal consumes another

23. Insects Parasitoids Insects lay eggs on or in host, and host is consumed by larvae

24. Parasites and Disease Depend on host for nutrition

25. Cannibalism Predator and prey are the same species

30. TRAP #4 Tactics of the P R E D A T O R

31. BIGGER, WILDER, FASTER #5 Tactics of the P R E D A T O R

32. 700 lbs & built to kill

33. 200 mph

34. 17,000 lbs

35. RESPONSES OF THE PREY

36. RESPONSES OF THE P R E Y camouflage #1

37. There are two major types of camouflage: Cryptic Camouflage Disruptive Camouflage

38. When an organism conceals itself by appearing like parts of its surrounding environment Cryptic Camouflage

39. chameleon cuttlefish octopus 3 organisms that can control the coloration Cryptic Camouflage

40. When patterns or colors are used to confuse predators to hide the head or tail areas of an organism Disruptive Camouflage

41. Disruptive camouflage confuses predators. Disruptive Camouflage

42. Other organisms have fake eye spots or other patterns so predators attack the wrong end

43. ESCAPE #2 RESPONSES OF THE P R E Y

44. POISON #3 RESPONSES OF THE P R E Y

45. Poison dart frogs are small, brightly colored rainforest frogs that have very poisonous skin. Poison dart frog

46. Poison dart frogs

47. Its skin secretes a nerve toxin that can paralyze a potential predator fire salamander

48. Its body contain toxins which taste terrible to potential predators. monarch butterfly

49. ARMOR #4 RESPONSES OF THE P R E Y

50. PLAY DEAD #5 RESPONSES OF THE P R E Y

51. MIMICRY #6 RESPONSES OF THE P R E Y

52. Mimicry is when one species closely resembles another species to gain some advantage

53. There are two types of mimicry: Batesian Mimicry Muellerian Mimicry

54. When a species that is NOT dangerous mimics a species that IS dangerous Batesian Mimicry

55. When two dangerous species mimic each other Muellerian Mimicry
