What is all that area that contains life called?

5. Ecology is the study of the relationships
between living and non-living things.
What is all that area that contains life called?
The Biosphere- Anywhere life exists. Examples = land, water, & air

6. Biome -similar climate & species
Ex = tundra, temperate forest

7. Interacting biotic and abiotic factors.
Where life exists –land, water, & air
Biome /similar climate & species
Ecosystem
Interacting biotic and
abiotic factors.
Different populations in
an area

11. Populations of species that interact can
have a variety of relationships.
Parasitism…

12. Parasites drain energy from other living
organisms

13. Populations of species that interact can
have a variety of relationships.
parasitism
predator – prey (predator eats prey)

14. Populations of species that interact can
have a variety of relationships.
parasitism
predator - prey

15. Populations of species that interact can
have a variety of relationships.
parasitism
predator – prey
mutualistic symbiosis (2 organisms live
closely together both benefit.

have a variety of relationships.

commensalism (2 organisms live
closely together 1benefits the other is
neither helped or harmed.)

monarch = poisonous
viceroy = nonpoisonous

19. How did the viceroy evolve to use this type of camouflage?
viceroy = nonpoisonous
monarch = poisonous

20. Ecology is studied in a variety of ways.

21. What is the ultimate source of energy for
most life on Earth?

22. What is this ?
Decomposers
bacteria & fungus
bacteria & fungus

23. Food Chains show how energy moves
through the ecosystem.
What are the trophic levels in a food chain.
and what are some terms that describe them.

27. What can be shown with pyramids?
Ecological Pyramids
Section 3-2
Energy Pyramid
Shows the relative amount of
energy available at each trophic
level. Organisms use about 10
percent of this
energy for
life processes.
The rest is lost
as heat.
Pyramid of Numbers
Shows the relative
number of individual
organisms at each
trophic level.
Biomass Pyramid
Represents the amount of
living organic matter at each
trophic level. Typically, the
greatest biomass is at the
base of the pyramid.
Go to Section:

28. Matter is not created or destroyed it is
cycled through living and non-living parts
of the environment.
List 3 examples of Matter that cycles.
(Hint- think elements.)

30. Water Cycle

32. Carbon Cycle

34. Phosphate Cycle

37. carbon + water + nitrogen + phosphate =

39. carbon + water + nitrogen + phosphate =
C HO N P
CHO
CHON
CHONP

40. carbon + water + nitrogen + phosphate =
C HO N P
CHO - carbohydrates and lipids
CHON - proteins
CHONP – nucleic acids
CHONPS- some of protein’s amino acids
require sulfur

41. Sulfur Cycle
Some amino acids also require sulfur

42. Limiting factors can prevent or limit growth.
Why was your bean not growing when you
first got it? (what was the limiting factor)

43. nitrogen deficiency
normal growth
Why does limiting nitrogen cause so many
problems?

44. Nutrients provide material for growth and
living. Anytime there is not enough of
a required nutrient growth and life is limited.

45. The more productive the ecosystem
the more standing biomass.
What is the most productive ecosystems?

46. Pollution can be chemicals, nutrients,
conditions, or structures that are harmful.
Its amazing just how large a problem this
can be!

47. Eutrophication is the gradual filling in of
bodies of water through the build up of
sediment.
How would an algae bloom affect this?

48. How can eutrophication be sped up by
human activities?

49. If there are lots of plants why would other
organisms die?

53. How can you help.

54. Encourage Others to Conserve
Reduce, Reuse, Recycle
Use Less Heat and Air Conditioning
Change a Light Bulb
Buy Energy-Efficient Products
Plant a Tree
Use the "Off" Switch
Get a Report Card from Your Utility Company
Use Less Hot Water
Drive Less and Drive Smart
Use less harmful substances.
Encourage Others to Conserve

55. Some things like mercury are
bioaccumulative.
It becomes more
concentrated as
you go up the
food chain.
How can you
reduce this
problem?
