Title: Ecological Principles


1
Ecological Principles
2
Objectives
  • Define Ecology
  • Compare and contrast biotic and abiotic factors
  • Describe the three types of symbiosis

3
ECOLOGY
  • is the study of the interactions among organisms
    and their environment
  • studied by an ecologist

4
THE ENVIRONMENT
5
  • An organisms surroundings
  • Composed of living (biotic) and nonliving
    (abiotic)things
  • Biotic Factors humans, plants, birds, fungi,
    bacteria, protists
  • Abiotic Factors water, light, temperature, air,
    soil

6
LIVING RELATIONSHIPS
7
  • Describes the associations that organisms have
    with other organisms of a different species
    within the environment

8
Symbiosis
  • A relationship between organisms in which at
    least one of them benefits
  • Three types of symbiosis in ecosystems are
    mutualism, commensalism, and parasitism.

9
Mutualism (, )
  • Both species benefit
  • from being in
  • relationship with
  • one another
  • ex. honeybee
  • flower

10
Commensalism (, 0)
  • One
    organism benefits
  • while
    the other is

  • unaffected (neither
  • helped
    nor harmed)
  • Ex.
    robin in a tree

11
Parasitism (, -)
  • One organism benefits at
  • the expense of the other
  • One organism benefits,
  • other harmed but not
  • not killed
  • Example
  • deer tick on a deer

12
Predation (, -)
  • one organisms benefits
  • by hunting, killing, and
  • feeding on another
  • organism
  • AKA predator prey
  • relationship

  • fox rabbit

13
  • predator organism that hunts, kills, and feeds
    off another
  • prey organism that is hunted killed

14
Competition
  • Occurs when organisms in the same ecosystem are
    competing with each other for resources such as
    food, water, sunlight, and living spaces

15
Objectives
  • Describe plants and animals found in various
    biomes
  • Identify the biome that we live in

16
BIOMES
17
  • A large region that contains similar plant and
    animal ecosystems and is characterized by certain
    climate conditions.
  • Biomes can be terrestrial (land) or aquatic
    (water).

18
Terrestrial Biomes
19
Temperate Deciduous Forest
  • Trees (birch, oak, maple,
  • elm) lose leaves in fall
  • Animals such as bears,
  • deer, rabbits, squirrels,
  • many species of birds

20
Coniferous Forest
  • Cone shaped trees (fir,
  • pine, spruce)
  • Moose, bears, lynxes
  • wolves
  • Snow covered ground
  • during long winters

21

22
Tropical Rain Forest
23
  • Made up of tall trees with broad leaves that form
    a dense canopy of vegetation
  • Animals include a wide variety of snakes,
    lizards, colorful birds, and many kinds of monkeys

24
Grassland
  • Made up of
  • grasses plants
  • that produce
  • colorful flowers
  • Called a prairie in
  • U.S.

25
  • Has rich, fertile soil
  • Well suited for growing crops
  • Animals include bison, mice, and prairie dogs

26
Desert
27
  • Arid or dry
  • Very little yearly rainfall
  • Vegetation sparse, consists of plants like cacti
  • Animals include snakes, lizards, and jackrabbits

28
Tundra
29
  • Very cold conditions
  • Very little vegetation
  • Contains permafrost (permanently frozen soil
    located underneath topsoil
  • Animals include musk oxen wolves

30
Aquatic Biomes
  • Aquatic biomes can be freshwater or marine

31
  • Freshwater biomes include rivers, streams, lakes,
    ponds, and wetlands
  • Wetlands are land
  • areas that remain
  • wet for all or part
  • of the year.
  • They include
  • swamps marshes

32
  • Marine biomes consist of the oceans

33
  • Oceans have 4 distinct zones
  • intertidal
  • neritic
  • oceanic
  • benthic

34
  • Intertidal where ocean meets the land. Animals
    include shellfish birds
  • Neritic numerous fishes, sea turtles, squids,
    coral reefs

35
  • Oceanic open ocean most of zone cold dark
    not much life. Fishes whales
  • Benthic ocean floor bottom feeder animals like
    starfish, anemones, sponges
