b.- THE MAIN CHARACTERISTICS OF AN ECOSYSTEM 

1.- Living things in an ecosystem include plants (flora), animals (fauna), fungi and microorganisms.

 2.- The non-living components of an ecosystem are: soil (with rocks and minerals), air, water, sunlight, temperature and climate.

 

3.- The place where a plant or animal normally grows or lives is called a habitat.The habitat of camels is arid areas and dry deserts.

 4.- All living things adapt themselves to help them survive in their environment. Penguins, for example, have adaptations to protect them from cold temperatures.

 5.- An ecosystem doesn´t have a particular size.  

 ( Un ecosistema no tiene una forma particular).

6.- They can be very big, big, medium, small and tiny.

( Ellos pueden ser muy grandes, grandes, medianos, pequeños y muy pequeños ).

7.- A tiny drop of water is an ecosystem.

( Una pequeña gota de agua es un ecosistema ).

8.- The biggest ecosystem on planet Earth is the Earth itseft.

( El mayor ecosistema del Paneta Tierra es la Tierra ).

9.- Ecosystems can be terrestial and aquatic, natural and man-made.

Los ecosistemas pueden ser: terrestres y acuáticos, naturales y hechos por el hombre).

 

 

c.-  TYPES OF ECOSYSTEMS

Natural ecosystems can be terrestrial or aquatic.

The Earth’s main terrestrial ecosystems are: tundra, different types of forests, different types of grasslands, tropical rainforest and desert.

 ( los  principales ecosistemas de la tierra son: tundra, diferentes tipos de bosques, diferentes tipos de sabana, bosques tropicales y desierto ),

 

Aquatic ecosystems can be marine; seas and oceans or freshwater; lakes, rivers,...                                                    

(Los ecosistemas acuáticos pueden ser: de agua salada; mares y oceános o de agua dulce; lakes, rivers, ... )

APART FROM THESE NATURAL ECOSYSTEMS, THERE ARE MAN-MADE ECOSYSTEMS AS WELL SUCH AS AQUARIUMS.
( Además de estos ecosistemas naturales, hay ecosistemas hechos por el hombre tambiém, como los acuarios, las ciudades, etc
