Title: Interaction of living things and cycles in nature.


1
Interaction of living things and cycles in nature.
  • Chapter 2 and 3 review

2
The five levels of environmental organization.
  • Organism one organism of one species.
  • Population two or more organisms of the same
    species.
  • Community different populations of organisms
    living together.
  • Ecosystem a community of organisms and the
    abiotic factors.
  • Biosphere the part of Earth where life exists

sequence.

Two main part of an environment
  • Biotic Factors all the living organisms that
    live and interact with one another.
  • Abiotic Factors all the non-living elements of
    an environment.

7
Links in a food chain
  • A food chain shows the pathway of energy transfer
    as a result of how organisms eating patterns.

8
Sun
  • The ultimate source of energy for all living
    things.

9
Producers
  • Producers make their own food through a process
    called photosynthesis. This requires sunlight.

10
Consumers
  • Consumers can be level one (primary) or level two
    (secondary) consumers.
  • Level one consumers can be herbivores which mean
    they only eat plants, or omnivores which means
    they plants and animals.
  • Level two consumers can be omnivores or
    carnivores which eat only meat.

11
Level one consumers
12
Level two consumers
13
Scavanger
  • Scavengers are consumers that eat the left overs
    of other consumers.

14
Decomposers
  • Decomposers break down dead organisms and return
    nutrients to the soil.

15
Food Web
  • A food web shows the feeding relationships
    between lots of different organisms in an
    ecosystem.

16
Can you answer these questions?
1. Name the living things in the food web that
are producers. ______________________ ____________

food web that are consumers. ____________________

does the snake eat? ______________________________

eat? ______________________________________ 5.

as? ______________________________________
17
Energy Pyramid
  • An energy pyramid shows an ecosystems loss of
    energy as it passes from one organism to the
    next.
  • An ecosystem must have more producers than
    consumers or it will collapse.
  • An ecosystem must have more level one consumers
    than level two consumers are it will collapse.

18
What does an energy pyramid look like?
19
Limiting Factors
  • The growth of a population is controlled by
    limiting factors.
  • Limiting factors are resources that are necessary
    for life.
  • Limiting factors are food, water, space. Amount
    of sunlight, temperature and other natural
    resources.

20
Carrying capacity and competition
  • Carrying capacity is the largest population an
    ecosystem can support. Limiting factors control
    the carrying capacity of all ecosystems.

21
Competition
  • Competition is when two or more individuals or
    populations complete for the limiting factors
    that are available in a particular ecosystem.

22
Predators
  • Predators are organisms that all or part of
    another organism. Predators are hunters.

23
Prey
  • Prey are organisms that are killed and eaten by
    other organisms.

24
What are adaptations?
  • Adaptations allow predators to catch their prey,
    but also allow prey to escape predators.
  • Some adaptations are
  • Camouflage speed staying in herds defense
    chemicals quills talons.

25
Mutualism
  • Mutualism is a symbiotic relationship in which
    both organisms benefit.

26
Commensalism
  • Commensalism is a relationship where one organism
    benefits and the other is not affected.

27
Parasitism
  • Parasitism is a relationship in which one
    organism benefits and other is harmed.

28
Water cycle
  • The water cycle is the movement of water between
    oceans, atmosphere, land and living things.
  • The main parts are
  • Evaporation
  • Condensation
  • Precipitation
  • Run-off

29
Water Cycle
30
Carbon Cycle
  • The carbon cycle is the exchange of carbon
    between the environment and living things.
  • Photosynthesis is the basis of the carbon cycle.

31
Nitrogen Cycle
  • The nitrogen cycle is the movement of nitrogen
    between the environment and living things.
