• ecosystem where biotic and abiotic
• factors interact with tehe enviroment naturally
• they can be:

• ARTIFICIAL
• they are
• man-made
• cities

ARTIFICIAL ECOSYSTEM

• THEY NEED HUMAN TO TAKE CARE OF THEM.FOR EXAMPLE ARE....
• GREEN HOUSE
• PARKS
• ZOOS
• TOWNS
• CROP FIELDS

NATURAL ECOSYSTEM

• TERRESTRIAL ECOSYSTEM
• they are located in london.
• they very depending on:
• altitude,sunligth,temperature,rainfall,soil
• AQUATIC ECOSYSTEM
• they are located in the water.
• they very depending on:
• salinity,sunligth,depth,water rate flow,oxigen

AQUATIC ECOSYSTEM

• FRESHWATER
• they are found in:
• rivers.
• lakes.
• pond.
• streams.
• wedlands.
• MARINE ECOSYSTEM
• they are foun in:
• oceans
• seas

FRESHWATER ECOSYSTEM

• RIVERS:AMAZON RIVER POND-POZA
• LAKES:LOCH NESS MARSH-MARISMA

FRESHWATER ECOSYSTEM

• wedlan are very famous attraction in florida
• living in them you can see a very special inhabitant.
• do you knoy which une?

AQUATIC ECOSYSTEM FACTORS

• SALINITY:amount os salt disolved in the water.
• freshwater | river ----------------------------------- least salty
• ecosystem | estuary -----------------------------------
• marine |
• ecosystems | ocean --------------------------------------most salty

AQUATIC ECOSYSTEM:FACTORS

• / DEPTH:distance from the surfance to the bottom
• /
• / LIGTH LEVEL:amount of ligth on a surface or area

AQUATIC ECOSYSTEM:FACTORS

• WATER FLOW RATE:the amount of water that passes through a giveng surface per minute

FRESHWATER ECOSYSTEM

• a body of brakish water
• (fresh water mixes with salty water)
• found where
• revers meet the sea.
• it is the widest part of a river

MARINE ECOSYSTEM

• SEAS
• OCEANS

Folie 13

• THE COSTAL ZONE:
• it extends from the land to wear sunligth penetrates the water so,photosynthesis is possible.
• THE MIDDLE ZONE:
• it is beteen the 200and 1000 m deep.there is very little ligth so, photosyntesis its no possible,so plants don`t live heare but many animals do.
• THE DEEP/DARK ZONE:
• its extend froom 1000 m deep to the botton of the ocean floor.There is no ligth heare.fish feed on the remains of organims from above

MARINE ECOSYSTEM

• PRODUCERS CONSUMERS PREDATOR
• PHITOPLAKTON \ ZOOPLAKTON \ FISH LARVE \ SMALL FISH \ GRAND FISH

FOOD CHAIN

• A food chain shows who eats whom to get energy/foot from eating and survive.
• food chains begin with a plant and end with an animal

FOOD WEBS

• THE FOOT WEB IS A GROUP OF INTERCONNECTED FOOD CHAINS.
• MOST LIVING THINGS ARE PART OF SEVERAL FOOD CHAINS IN A ECOSYSTEM.
