THE OCEAN

BIOTIC :

  • sharks
  • whales
  • dolphins
  • sea horses
  • little fishes
  • sea shells,ect...
  • seaweeds
  • algae

ABIOTIC:

  • water
  • sunlight
  • temperature
  • wind nutrients
  • aeral exposure

CARRYING CAPACITY

A carrying capacity is the size of the population that can be supported indefinitely upon the available ressources and services of that ecosystem.

In the coast of los angeles,the carrying capacity of Great White sharks is about 10 because the coast is small and there is less algae and if there is less algae, there is less fish which means less sharks,it is just like a food chain.

LIMITED FACTORS

A limited factor is when a presence or an absence of a factor limits the growth of a ecosystem element.

The limited factors of the Great White sharks are the climate, the population growth and being hunted .

ENERGY ROLES

Producers: they are any kind of green plants;they take enrgy from the sun.Some examples of the producers in the ocean are:

  • seaweed
  • algae
  • sea grasses

Consumers:they are any organism that can't make their own food;they take energy from the producers.some examples of consumers are:

  • lobsters
  • shrimps
  • mussules

Decomposers: an organism that primary feeds on dead organisms or the waste from living organisms;they take energy from the consumers.Some examples of decomposers are:

  • bacteria
  • fungi

FOOD CHAINS AND FOOD WEBS

Food webs are more realistic than food chains because food webs consists of all different food chains in a particular ecosystem.

For example, if you take away the small sharks, the large sharks population would decrease.

TROPIC LEVELS AND ENERGY PYRAMIDS

We use a pyramid shape to let people see that the bottom of the pyramid get more energy than the top.

The producers get more energy than the top level because each level each level get 10% of the level before it.

PHOTOSYNTHESIS

The chemical equation of photosynthesis is C6H1206.

The essential ingredients in photosynthesis are :

  • sunlight
  • chlorophyll
  • water
  • carbon dioxide

Glucose is produced by photosyntesis.

TROPISMS

a tropism is the turning of all or part of an organism in a particular direction in response to an external stimulus .

Some example of tropisms in the ocean:

  • algae
  • seaweed
  • saegrasses

For example,sunlight helps algae make food an grow.

THE ROLE of DECOMPOSERS

The ocean needs decomposers because they ingest waste and convert it into essential nutrients back into the ocean ecosystem.

If there were no decomposers in the ocean there would be pile of dead organisms and the nutrients in the waste and dead organisms would not be release back into the ecosystem.

Some examples of decomposers are:

  • bacteria
  • fungi

great examples, but make sure to give the definitions for carrying capacity and limiting factors.
