Ecosystyms:Oceans

The ocean is home to many variaties of living creatures to non-living things   from seaweed to octopus. Here's what the ocean is about.

Facts about the ocean

-the average temperature is about 63 degrees fahrenheit on the surface and the average  is 29 degrees fahrenheit the ocean reef
-The open ecosystem contains the largest ecosystem in the world



Biotic Factors
-fish
-whales
-sharks
-dolphins
-coral

Abiotic factors
-sunlight
-water
-moisture
-tempature
-soil type


Carrying capacity
carrying capacity- the maximum population that an area will support without undergoing deortation

fish can die if they don't have resourses they need

predator/prey relationships:
limiting factors- an environmental  factor that tends to limit population size

sharks/ fish
octopus/plankton

Energy roles
Producers- are also called autotrophs,they receive their energy from the sun,make their own food through photosynthesis,and provide the most energy that feeds the rest of the ocean ecosystem.producers-seaweed
consumers-fish, sharks,whales and more
decomposers-algi, plankton,and various bacterias

Consumers- are also called heterotrophs, they don't make their own food,they feed on other organisms(plants and animals) ,receive their energy by consuming other organisms,and there are 4 types of consumers which are herbivores, carnivores, omnivores, and scavengers.

Decomposers- organisms that break down wastes and dead organisms and return the nutrients back into the environment.

Food chains and food webs

food web
alge- any kind of fish-octopus-blue whale

Trophic levels and food pyramids

Photosyntheseis

During the process of photosynthesis plants break apart the reactants of carbon dioxide and water and recombine them to produce oxygen (O2) and a form of sugar called glucose (C6H12O6).

Photosynthesis takes place inside plant cells in small things called chloroplasts. Chloroplasts (mostly found in the mesophyll layer) contain a green substance called chlorophyll. Below are the other parts of the cell that work with the chloroplast to make photosynthesis happen

Plants use energy from sunlight to turn water and carbon dioxide into an energy-rich sugar called glucose. This process is called photosynthesis, which means “making things with light”. Photosynthesis takes place inside capsules in the leaf cells, called CHLOROPLASTS.

Tropisims

Tropisms are directional movement responses that occur in response to a directional stimulus. Plants are not able to relocated if they happen to start growing where conditions are suboptimal.

- seaweed

-sea cucumber

- algae

- kelp

-seagrass

plants like seaweed help the ecosystem survive because the first consumers need it

The role of decomposers

Decomposers are vital in the ocean because they have to break down the dead organisms at the bottom of the ocean to get back the nutrients from them and give it off to the living organisms.If there were no decomposers the effects would be that the ecosystem wouldn't have a lot of nutrients,the soil will not be healthy,and plants would not produce.

Some decomposers that are in the ocean are shrimp,brittle stars,starfish,crabs,sea urchins,and seaweed.

Adaptations

The adaptions purpose is to enable traits so organisms can survive in their ecosystem and there are two types of adaptations structural and behavioral;structural is the physical features of an organism and behavioral is how an organism acts.These adaptations adapt to the ocean.

You need to identify the difference between a web and a chain, and explain why a food web makes more sense. Also, make sure to include definitions of producers, consumers, and decomposers. You've included a lot of great information, but it would look better in maroon! 😄
