33. CONSUMERS EAT PRODUCERS & OTHER CONSUMERS!
WHAT DO YOU CALL THESE GUYS? CONSUMERS
PRODUCERS aka AUTOTROPHS
CONSUMERS EAT PRODUCERS & OTHER CONSUMERS!

34. CONSUMERS a.k.a. HETEROTROPHS!
The creatures ABOVE producers on the food chain are aka CONSUMERS aka HETEROTROPHS
PRODUCERS aka AUTOTROPHS
CONSUMERS a.k.a. HETEROTROPHS!

35. but it all begins with the Sun (unless you are in the benthic zone)!
CONSUMERS aka HETEROTROPHS
PRODUCERS aka AUTOTROPHS
but it all begins with the Sun (unless you are in the benthic zone)!

36. but wait! we almost forgot someone!

37. DON’T FORGET! decomposers are heterotrophs TOO-THAT EAT dead PRODUCERS & CONSUMERS TO return nutrients back to the producers!

38. DON’T FORGET! decomposers are heterotrophs TOO-THAT EAT dead PRODUCERS & CONSUMERS TO return nutrients back to the producers!

39. decomposer= detrivores
DON’T FORGET! decomposers are heterotrophs TOO-THAT EAT dead PRODUCERS & CONSUMERS TO return nutrients back to the producers!

40. CONSUMERS THAT EAT ONLY PRODUCERS (HERBIVORES) ARE PRIMARY CONSUMERS

41. CONSUMERS THAT EAT ONLY PRODUCERS (HERBIVORES) ARE PRIMARY CONSUMERS

42. IS THIS A FOOD CHAIN OR WEB?

43. food chains show a single relationship between species.
THIS A FOOD CHAIN!
food chains show a single relationship between species.

44. THIS IS A
FOOD WEB
IT SHOWS
MANY
RELATIONSHIPS
BETWEEN
PRODUCERS &
CONSUMERS.

45. A FOOD WEB IS made up of MANY FOOD CHAINS.

46. A FOOD WEB IS made up of MANY FOOD CHAINS.
How MANY food chains are here?

47. A FOOD WEB IS made up of MANY FOOD CHAINS.
How MANY food chains are here? 18

48. ARROWS point TO the
CONSUMER, & SEPARATE
EACH TROPHIC LEVELS

49. ARROWS point TO the CONSUMER, & SEPARATE EACH TROPHIC LEVELS
CAN YOU COUNT the RANGE of TROPHIC LEVELS among all the FOOD CHAINS in this
FOOD WEB?

50. ARROWS point TO the CONSUMER, & SEPARATE EACH TROPHIC LEVELS
CAN YOU COUNT the RANGE of TROPHIC LEVELS among all the FOOD CHAINS in this
FOOD WEB? 3 to 6

51. How many trophic levels does the nematode belong
to here?

52. How many trophic levels does the nematode belong
to here? 3 (2nd, 3rd and 4th trophic levels)

53. How many detrivores does this food web have?

54. How many detrivores does this food web have?
2: bacteria and fungi break down organic waste.

55. How many autotrophs are in this food web?

56. How many autotrophs are in this food web?
Only 1 mentioned here (plants)

57. Are protozoa primary consumers here?

58. Are protozoa primary consumers here? No, they eat
bacteria, not the plant (producer/autotroph).

59. How many organisms are ONLY primary consumers?

60. How many here are ONLY primary consumers? NONE?
Fungus eat the plant, & also decompose dead organic
matter. Nematodes eat producers & consumers.

61. PRODUCERS (photo & chemosynthesizers) = AUTOTROPHS CONSUMERS = HETEROTROPHS PRIMARY CONSUMERS = HERBIVORES SECONDARY CONSUMERS = CARNIVORES DECOMPOSERS = DETRIVORES
