1 Biology Ecosystems

2 Objective Organisms cooperate and compete in ecosystems

3 Ecology

4 The study of ecosystems
Ecology The study of ecosystems

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

6 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.

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

8 A niche may apply to species, populations, or even individuals

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

10

11 After years of searching Walter finally found his niche.

12 Habitat The physical area in which an organism lives.

13 Niche The way of life of an organism.

14 Prey Predator Predator's predator Predation

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

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

17 Carnivores Herbivores Omnivores eat only meat eat only plants
eat plants and meat

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

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

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

22 Tertiary Consumers eat secondary consumers.

23 Food Web

24 Interrelated food chains within an ecosystem.
Food Web Interrelated food chains within an ecosystem.

25 Why don't humans eat carnivores?

26 Spark 2 topics you feel are
Most important to slow the change of our ecosystem Most easily changed behavior.

30 Kingfisher Trout Insect Larvae Producers 100% Algae

31 All producers are able to make their own food through photosynthesis.

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

33 Primary Consumers 10% Producers 100%

34 Primary consumers feed on producers. Primary Consumers 10%

35 Primary consumers use 90% of their food energy to stay alive.

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

40 ALL food chains, food webs, and food pyramids begin with producers.

41 A normal food pyramid looks like this.

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

43 Protective Coloration

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

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

46 Which one is poisonous? Mimicry

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

48 Symbiosis is a close association between two dissimilar organisms.

49 One organism benefits (parasite), the other is harmed (host).
Parasitism One organism benefits (parasite), the other is harmed (host).

50

51

52

53 One organism benefits, the other neither benefits or is harmed.
Commensalism One organism benefits, the other neither benefits or is harmed.

54

55 Both organisms benefit equally.
Mutualism Both organisms benefit equally.

56 Mutualism is common in nature.
