ECOSYSTEM IN COLOMBIA
Transcript of ECOSYSTEM IN COLOMBIA
This biome consists of two vegetation types : warm and cold desert Desert.
They have average temperatures ranging between 7 and 11 ° C and annual rainfall between 130 and 340 mm , depending on the area .
In the cold desert dominant life forms are geophytes and chamaephytes , coverage is very low and you can see only one layer . Function is deciduous and leaf type graminiforme is mostly small . This vegetation is active in the summer months .
The warm desert presents mostly chamaephytes and therophytes and like the cold desert coverage is very low. The vegetation is vertically arranged in two layers and the function is deciduous and sharpened. The predominant type of leaf is leathery . The areas where this vegetation is by water and wind erosion and heavy rains are characterized
CLASSIFICATION OF COLOMBIAN ECOSYSTEM
The most important terrestrial ecosystems of Colombia are:
Ecosystems are divided, generally, in terrestrial, in land water and marine. In Colombia, various systems have been applied for classification of ecosystems, especially of terrestrial ecosystems. The ecosystem classification presented below to Colombia, is defined according to the main types of ecosystems (TPE), which, by presenting variants related to habitat characteristics, leading to major habitat types TPH.
This ecosystem is famous for its exuberance and possessing one of the greatest diversity of plants and animals in the world. The vegetation is very developed and can be divided into many layers or "flats", depending on your height (ground, understory, canopy, emergent trees.) The canopy is typically formed by tall trees, 25-35 m tall; giant emergent trees exceed 50 m in height.
The temperate coniferous forest is a forest corresponding to temperate coniferous, evergreen vegetation, with warm summers, cold winters and adequate rainfall where gymnosperms or coniferous trees dominate terrestrial biome.
This group brings together diverse ecosystems such as savannahs, wetlands and moors, which have in common the predominance of non-tree species widely distributed. These, in turn, are subdivided into the following types of habitat: seasonal savannas, flooded savannas, montane grasslands (moors) and scrub hills.
They are comprised mainly of mangroves, which are types of trees adapted to be submerged and are tolerant to salinity. Mangroves are found on the shores of the Caribbean Sea and Pacific Ocean.
Colombia has two kinds of aquatic ecosystems:
• FRESHWATER ECOSYSTEMS
• MARINE ECOSYSTEM
Freshwater ecosystems are freshwater bodies like rivers, lakes, swamps. They differ from marine ecosystems because they have a high concentration of salts.
Marine ecosystems are within aquatic ecosystems. They include oceans, seas and swamps, among others. Life arose and evolved in the sea. The marine environment is very stable when compared to terrestrial or freshwater habitats. The temperatures of large oceanic masses vary little and salinity (3.5%). The ionic composition of seawater is similar to the body fluids of most of the marine organisms. Our main marine ecosystems are:
• Coral formations or coral reefs.
• Coastal and rocky bottoms.
• Seascapes and sandy bottoms.
• pelagic systems.
