34. Biology 10/10 Warm up: In ecology, what does it mean if an organism is a consumer? Today’s activities: Notes + practice mini-quiz Read page 63-73 Food web posters due Today

35. ECOLOGICAL PYRAMIDS and the Transfer of Energy in Ecosystems Which animals are at each level? What type of ecological niche do they each belong to?

36. Ecological Pyramids: graphs which illustrate the trophic levels in a community.

37. Most ecological pyramids are large at the base and narrow at the top. This is because every time that an organism is eaten by the next trophic level, some of the energy is lost as heat. More Energy Less Energy

39. 3 TYPES OF PYRAMIDS: 1. Pyramid of Biomass 2. Pyramid of Energy 3. Pyramid of Numbers

40. Pyramid of Biomass: Illustrates the amount of biomass in each trophic level –Biomass weight is determined after dehydration Shows the amount of matter lost between trophic levels. Measured in Kg, grams or pounds

41. Pyramid of Biomass

42. Pyramid of Energy: Shows the energy available at each trophic level. –The size of the blocks represents the proportion of productivity –Measured in Joules or Calories

43. Pyramid of Energy: Most of the energy available to the community is in the 1st trophic level. Only 10-20% of the energy is available to the next trophic level (≈ 90% lost)

44. Pyramid of Numbers: Illustration of the number of organisms at each level

45. What kind of Pyramid is this? Energy, the trophic levels are measured in Kilocalories

46. How can more people be supported on Earth when there is a limited supply of resources? Human Population Growth It depends on what they are eating…

47. Mini-Quiz 10/10 1. What does a biomass pyramid illustrate? 2. If a 150 pound animal ate nothing but plants, estimate how many pounds of plant material it takes to build 150 pounds of animal biomass. 3. If a 150 carnivore ate nothing but herbivores, estimate how many pounds of plant material it takes to build 150 pounds of carnivore biomass. 4. Which category of organisms contain the most biomass on a biomass pyramid? 5. Which category of organisms contain the least biomass on a biomass pyramid?

48. Biology 10/9 Warm up: In ecology, what does it mean if an organism is a producer? Today’s activities: Notes + practice mini-quiz Read page 63-73 Food web posters due Thursday

49. Food Chains and Food Webs

50. What is a food chain? A food chain is “a sequence of organisms, each of which uses the next, lower member of the sequence as a food source”

52. Important facts about food chains In a food chain each organism obtains energy from the one at the level below. Plants are called producers because they create their own food through photosynthesis

53. Primary Producers Primary producers are “organisms capable of producing their own food” We can also say that they are photosynthetic, use light energy.

54. Primary Producers Examples of primary producers include algae, phytoplankton, and large plants. Primary producers are eaten by primary consumers (herbivores)

55. Important facts about food chains Animals are consumers because they cannot create their own food, they must eat plants or other animals to get the energy that they need.

56. Four types of consumer Herbivores: animals that eat only plants. Carnivores: animals that eat only other animals. Omnivores: animals that eat animals and plants. Detritivores: Animals that eat dead materials and organic wastes

57. Other Ways to Classify Consumers 1.Primary Consumers: Herbivores 3. 2.Secondary Consumers: Carnivores that eat herbivores 3. 3.Tertiary Consumers: Carnivores that eat other carnivores 3.

58. Mini-Quiz 10/9 1. 2 examples of producers 2. 2 examples of herbivores 3. 2 examples of carnivores 4. 2 examples of omnivores 5. 2 examples of detritivores
