Understanding the Circle of Life in Ecology

2. Answer in your science notebook: What do you think is meant by, “the circle of life?” Checking: Water and Carbon Cycle Questions

3. What is Ecology? • Ecology is the study of interactions between organisms and the living and non-living components of their environment.

4. * Clip 1: List two living and non living factors that you saw in the video clip from The Lion King. * Clip 2: What was the relationship that the living and non living factors shared with one-another in th video clip from The Lion King?

5. What is an Ecosystem? • Interacting groups of Species and their environment • Consists of both biotic and abiotic factors • Biotic Factors: Living things • Ex: Birds, tiger, bees, etc. • Abiotic Factors: Non Living things • Ex: water, oxygen, rocks, etc.

6. Abiotic Vs. Biotic Factors Animals: Biotic Rocks: Abiotic Weather: Abiotic Flowers/Plants: Biotic Temperature: Abiotic

7. Who’s Who in an Ecosystem?

8. Levels of Organization • Make like a pyramid so you know which group is the most inclusive and which group is the least inclusive. • Along with the label, and picture (colored), include the definition for each level.

9. Biome Matching

10. Match each plant/animal with the appropriate biome. • Take notes on each biome and the types of plants and animals that live there. • Why is it important to protect biodiversity in each biome?

11. Food Chain/ Food Web Guided Reading • Due Monday

12. Reflection • Which level of organization do ecologists start to look at both biotic and abiotic factors together?

13. Bell Work • Describe what you think the difference between a food chain and a food web is? • Assignment: Food Chain/Web Questions and diagram Stamp: Levels of Organization Diagram (levels labeled, pictures colored, and definition)

14. Reflection: Can an organism be classified as both a consumer and a producer? Why or why not?

15. Bell Work • What is the definition of a trophic level? What is the first trophic level that a food chain or a food web begins with? • Assignments: • Review Food Chains/Food Webs • Population Ecology Graphs (3 by tomorrow) • Stamp: Food Chain/Food Web Questions *Midterm review grades going in today

16. AUTOTROPHIC(PRODUCER): organisms that make their own energy. • EX: plants, algae, certain bacteria • HETEROTROPHIC (CONSUMER): organisms that consume their own food for energy. • EX: animals • DECOMPOSER –organisms that breaks down organic substances • EX: certain bacteria, fungi, worms

19. Type of Consumers • Herbivore – an organism that gets its energy by consuming plants.= primary consumers • Carnivore – an organism that gets its energy consuming meat. = second consumers & tertiary consumers • Omnivore – an organism that gets its energy by consuming both plants and meat.= secondary consumers & tertiary consumers • Detrivore- organisms that eat dead/rotting organisms • EX: worms, vultures, & arthropods

21. Trophic Level (feeding/energy level)- consists of all organisms feeding at the same energy level

26. Ecological Pyramid of Trophic Levels

27. Ecological Pyramid of Trophic Levels

28. Create your own FOOD WEB Pick a biome you just researched. Draw a food web with ten organisms. You must have one of each of the terms below. Label what each organism is (they may be more than one, so put all that they are): • Heterotroph • Decomposer • Primary Consumer • Secondary Consumer • Tertiary consumer • Herbivore • Carnivore • Omnivore • Detrivore • Autotroph/Producer Your food web needs to be colored, organized, and demonstrate effort.

29. Reflection Name one of the following from the movie The Lion King: • Omnivore • Carnivore • Herbivore Are they considered an autotroph or heterotroph?

30. Bell Work • Begin your graphs right away. In 20 minutes we are moving on to the group activity and you need them done. • Assignment: Population Ecology • Stamp: Graphs (3)

31. VOCABULARY • BIOSPHERE- broadest, most inclusive = the thin volume of Earth and its atmosphere that supports life.

32. VOCABULARY • ECOSYSTEMS- includes all of the organisms and the non-living environment found in a particular place.

33. VOCABULARY • COMMUNITIES- includes all the interacting organisms living in an area.

34. VOCABULARY • POPULATIONS- includes all the members of a species that live in one place at one time. • ORGANISMS- simplest level= individual

35. VOCABULARY • HABITAT- WHERE LIVING ORGANISMS LIVE. • NICHE- A SPECIES WAY OF LIFE, OR THE ROLE THE SPECIES PLAYS IN ITS ENVIRONMENT.

36. VOCABULARY • HABITAT- WHERE LIVING • ORGANISMS LIVE. • NICHE- A SPECIES WAY OF LIFE, OR THE ROLE THE SPECIES PLAYS IN ITS ENVIRONMENT.

38. Biome Poster Example

39. Requirements for Biome Pyramid • You must include the title of your biome (total of 6 biomes) • -You must include 5 biotic factors: • 5 plants or animals • -You must include 2 abiotic factors: • You can choose any 2 abiotic factors (ex: humidity, temperature, percipitation, • Location of the Biome • Creativity and neatness

40. Cycle Notes • Nitrogen Cycle and Carbon Cycle • http://www.dpi.vic.gov.au/vro • Keyword: Nitrogen Cycle • Keyword: Carbon Cycle • Water Cycle • http://teacher.scholastic.com/activities/studyjams/water_cycle/

41. Interactions between Species • How can prey avoid getting captured?

43. Mimicry • Resemblance of a distasteful or poisonous species http://www.youtube.com/watch?NR=1&v=t-LTWFnGmeg&feature=endscreen

44. Camouflage http://www.youtube.com/watch?v=SCgtYWUybIE&feature=fvst

45. Camouflage • The ability to blend in with the environmental surroundings http://www.youtube.com/watch?v=SCgtYWUybIE&feature=fvst

46. WHERE’S THE FOX?

47. Bell Work • What does symbiosis mean? Do you know the different types of symbiosis? • Assignment: Symbiosis game

48. Species Relationships Symbiosis

49. Species Relationships • Symbiosis: 2 or more species live together in a close long-term relationship. • Examples: Parasitism, Mutualism, & Commensalism

50. Parasitism-
