TEMPERATURE, WATER, SOIL, ROCKS...

TYPES OF ECOSYSTEMS :TERRESTRIAL ECOSYSTEMS

ecosystems

RELATIONS

among living things in an ecosystem are given different relationships:

relations of power

competitive relationship

cooperative relationships

feed in ecosystems

producers: plants make their own food.consumers

primary: herbivores animals secondary: carnivorous animals

Carnivorous animals

• carnivorous animals eat other animals

food chains• the food chain is the way to represent the mode in

which is feed on living things in an ecosystem

COMPETITION• THE LIVING BEINGS COMPETE

WHEN THEY HAVE A NEED.

• PLANTS COMPETE FOR SUNLIGHT, GROW MORE QUICKLY.

• ANIMALS COMPETE FOR FOOD, TERRITORY.

THE COOPERATION

• THE COORPORACIÓN OCCURS WHEN TWO LIVING BEINGS ARE COLLABORATING AND WILL BENEFIT

CONSERVATION OF ECOSYSTEMS

• :

ECOSYSTEMS ARE IMPAIRED

ECOSYSTEMS ARE IMPAIRED BY

• POLLUTION

• DEFORESTATION

• OVEREXPLOITATION

THE CONTAMINATION

pollution can affect water, air

and soilamong the causes of

pollution are waste and

smoke

REDUCE CONTAMINATION

using clean transportationdepositing trash in proper containers for recycling

The deforestation

deforestation is the loss of forests for timber or crops when forests disappear, disappear also the animals that inhabit

THE EROSION

trees are cut when the ground is bare and the rain and the wind drag

the ground. soil loss is called erosion

and damages the ecosystem even more

the overhuntingoverexploitation occurs when an ecosystem take more animals or plants they produce. an example is tuna fishing has endangered the survival of spice

ecosystem protection

ecosystems are protected by the laws of the declaration space-protecting national parks as an example of this is the park closes snowfall santamarta
