Marine ecosystem :
Characteristics 
Are among of earth's  aquatic ecosystem . Examples include salt marshes , intertidal zones estuaries,  lagoos , mongroves , coral reefs , the deep sea and the sea floor . They can be contrasted . Supports the animal life and vice versa . See the food chain 

Food chain :  large shark > mahi mahi >mackerel>small fish> zooplankton > phytoplankton :

INTERACTS WITH HUMANS :
Negatives 
Humans living near the coast have probably always used the ocean as a source of food  . Fishing was probably the first use of the ocean by  humans in the comercial fishing have restulted in the over exploitation of many fish stoks.

RAINFOREST ECOSYSTEM

                               Characteristics: 

Location:

Are located in the equatorial zone between the tropic Cancer and Capricorn.

Temperature: 

Rainforest are forest characteristics by high rainfall.

Flora and Fauna: 

They may be many millions of species of plants, insects an microorganisms. Mammals , reptiles, birds and invertebrates.

Snakes, turtles , cuculidae and chamaleons.

Interaction with the humans: 

                                   Positives and negatives

 Have been called the jewels of the Earth and world`s largest pharmacy. Medicines , fungal infections , burns respiratory problems and wound treatment.Tropical rainforest provide timber as well as animal products such meat and hides

Also have value as tourism destinations and for the ecosystem services provided.

                                     Deforestation: 

Biologists have estimated that large numbers of species are being driven to extintion.

                                        Food chain: 

PRODUCERS: Plants produce their own food from the energy form the sun

HERVIBORES : these animals eat plants . the butterfly eat nectar form plants

OMNIVORES: these animals eat plants and animals.

CARNIVORES: these animals eat meat which includes animals and insects

RainForest

Characteristics

Giraffes:

  Giraffes are hebivores.

They can measure arround 6 metres!!!😉

 And they can weight 750 or 1600 kg !!!😊

 Some of the giraffes of west of Africa are on 

DANGER OF EXTINCTION !!!😭

Savanna have 2 seasons :

WET season 

and

DRY season

Here you can see that the wet season have more vegetation than the dry season.

VEGETATION :🌾

 They are: gramíneas, Triodia and Astrebla 

Sometimes this plants can measure more than 2 metres tall.

They are specially on savanna and deserts ( but I think warm

deserts).

FOOD WEB:🍗

The plants are eaten by:

elephants, antelopes,buffalos,

rhinos, zebras and giraffes.

 Elephants are eaten by the lion.

 Antelopes are  eaten by the lion.

 Meerkats are  eaten by the lion.

The lion isnt´n eaten by no one, but

we the lion die the decomposer eat

them.

Buffalo is eaten by the lion.

Rhinos are eaten by the lion.

Zebras are eaten by the lion.

And giraffes are eaten by the

lion.

INTERACTION WITH HUMANS:

Positive: 

The good people help to the animals and the 

plants , and some people to wanted to saved 

all the species that are in danger of extinction.

 Negative:

 We pollute a lot and we hunt animals , and sometimes,

we hunt  animals are on danger of extinction.

cold desert

COLD DESERT😋

Where can you find it?

We  can find it in: Antarctic, Greenland, Northern and Western China, Turkestan, Iran and the Nearctic area.

Characteristics:

Snow in winter, rain in spring and in autumn.

Summers are short and wet.

Average temperature in winter: -2º and 4º

Average temperature in summer: 21º and 26º

Vegetation:

There is little vegetation. Plants can be between 15 and 122 cm high.

In some areas we can find ground covers such as liquens. In other areas plants are far away from each other.

We can see grasses, shadscale and camelthorn.

Animals:

We can see deer and polar bear in winter.

We can see small mammals such as rats, miece, squirrels, fox, coyote and lizards in spring, summer and autumn.

Jack rabbits, snakes and wolves are part of this ecosystem too.

We see insects when it's rain season.

Foodchain:

Mosquito is eaten by lizzard.

Lizzard is eaten by fox.

Fox is eaten by wolf.

Wolf is eaten by descomposer when is dead.

Human interaction:

Cold deserts are areas with very few inhabitants. So human impact is very limited in cold deserts.

Positive:

Cold deserts are officially protected, banning many destructive human activities and allowing natural life to grow.

Negative:

Global warming is detroying many ecosystems due to the temperatura increase of the planet, caused by human actitity.

temperate forest

temperate forest

characteristics:

1. the weather is fresh
2. the precipitacion is great
3. is a lot of vegetación

the interaction by the humans

1. + the exploitation of forest
2. - we hunt a lot of animals that's why is are in danger of extinción

fun facts

1. trees in temperate forest can usually take cold water  , but they don't grow

food chain

the grasshoper eat th

e plant that are the producer, the mice eat the grasshoper the snake eat the mice , the Eagle eat the snake and when the Eagle die is eaten by a decomposer
