E.O.C Review
  • SC.912.L.17.9
  • Made by Janice Garcia

Producers
  • Producers get their energy from the sun through a
    process called Photosynthesis.
  • Plants take the sunlight and use its energy to
    make sugar.
  • The plant uses this sugar, also called glucose to
    make many things, such as wood, leaves, roots,
    and bark.
  • Oxygen is also produced by the plant in this
    cycle, which is then let off into the air

Consumers
  • Animals are called consumers because they can not
    make their own food, instead they eat other
    organisms.
  • There are 3 consumers
  • --PRIMARY CONSUMER
  • --SECONDARY CONSUMER
  • --TERTIARY CONSUMER

5
Primary Consumers
  • Primary consumers feed directly upon primary
    producers to obtain their nutrients and energy.
  • This group of organisms includes familiar grazers
    such as cattle, horses and zebras.
  • Example Grass is a producer. A dear is a
    Primary consumer. The dear eats the grass
    (producer).

6
Tertiary Consumer
  • A carnivore at the top level in a food chain that
    feeds on other carnivores or an animal that feeds
    only on secondary consumers and producers.
  • Tertiary consumers are mostly on the highest
    level of a food chain.
  • Some examples includes, lions, hawks and even
    humans.

7
Decomposers
  • Decomposers break down dead plants and animals.
  • They break down the waste of other organisms.
  • Decomposers are very important for ecosystems
    because if they weren't in the ecosystem, the
    plants would not get essential nutrients, and
    dead matter and waste would pile up.
  • Worms, molds, fungus, bacteria, and
    actinobacteria are some general categories of
    decomposers.

8
  • Trophic levels are the feeding position in a food
    chain such as primary producers, herbivore,
    primary carnivore, etc. Plants form the first
    trophic level, the producers. Herbivores form the
    second trophic level, while carnivores form the
    third and even the fourth trophic levels.
  • The feeding of one organism upon another in a
    sequence of food transfers is known as a food
    chain.
  • In an ecosystem there are many different food
    chains and many of these are cross-linked to form
    a food web.
  • There are 3 types of ecological pyramids .
  • -Number pyramid
  • -Biomass pyramid
  • -Energy pyramid

The Water Cycle
  • The water cycle is made up of different parts
  • -evaporation (and transpiration)
  • -condensation
  • -precipitation
  • -collection
  • EVAPORATION
  • -Evaporation is when the sun heats up water in
    oceans or other water sources and turns it into
    vapor. The water vapor or leaves the river, lake
    or ocean and goes into the air.
  • CONDENSATION
  • -Water vapor in the air gets cold and changes
    back into liquid, forming clouds. This is called
    condensation.

11
  • PRECIPIATION
  • -Precipitation occurs when so much water has
    condensed that the air cannot hold anymore. The
    clouds get heavy and water falls back to the
    earth as rain, hail, sleet or snow.
  • COLLECTION
  • -When water falls back to earth as precipitation,
    it may fall back in the oceans, lakes or rivers
    or it may end up on land. When it ends up on
    land, it will either soak into the earth and
    become part of the ground water that plants and
    animals use to drink. The cycle starts all over
    again.

12
Carbon Cycle
  • Carbon is a part of the ocean, air, rocks and
    even living things.
  • Carbon is attached to some oxygen in a gas called
    carbon dioxide.
  • Plants use carbon dioxide and sunlight to make
    their own food and grow. Plants that die and are
    buried may turn into fossil fuels made of carbon
    like coal and oil over millions of years.
  • When humans burn fossil fuels, most of the carbon
    quickly enters the atmosphere as carbon dioxide.

Energy in Joules
  • Joules is a measure of energy.
  • It measures heat, electricity and mechanical
    work. It was named after English physicist James
    Prescott Joule.
  • The joule is a unit equivalent to a Newton-meter,
    or a kilogram-meter squared per second per second.
