The Tropical Andes are located in South America following the path of the Andes. They run, mainly, through five countries, Venezuela , Colombia , Ecuador , Peru , and Bolivia . The land initially was roughly 1,258,000 km 2 (486,000 sq mi) but has decreased to 314,500 km 2 (121,400 sq mi), leaving 25% of the original land.
Map of the Andean region of South America. Current agricultural practices of the Andean region of South America typically involve a synthesis of traditional Incan practices and modern techniques to deal with the unique terrain and climatic elements of the area.
A freshwater aquatic food web. The blue arrows show a complete food chain (algae → daphnia → gizzard shad → largemouth bass → great blue heron). A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community.
The sparsely populated eastern slopes of the Andes enjoyed abundant precipitation and warmer temperatures than the highlands, but also had agriculture challenges such as steep terrain. This region was important for its tropical crops, bird feathers, gold, and wood. [14] [15] The Incas transported agricultural goods by llama caravan.
The presence of the various altitudinal floors of the Andes mountain range in Peru and its proximity to the geographical equator allows the existence of a series of microclimates and species, from areas of usual snowfall to tropical forests; With 84 of the 104 climatic zones on the globe, it is one of the 12 countries in the world with the ...
A food web model is a network of food chains. Each food chain starts with a primary producer or autotroph, an organism, such as an alga or a plant, which is able to manufacture its own food. Next in the chain is an organism that feeds on the primary producer, and the chain continues in this way as a string of successive predators.
It is between 4,500 and 4,800 m (14,764 and 15,748 ft) in the tropical Ecuadorian, Colombian, Venezuelan, and northern Peruvian Andes, rising to 4,800–5,200 m (15,748–17,060 ft) in the drier mountains of southern Peru and northern Chile south to about 30°S before descending to 4,500 m (14,760 ft) on Aconcagua at 32°S, 2,000 m (6,600 ft ...
Food chain in a Swedish lake. Osprey feed on northern pike, which in turn feed on perch which eat bleak which eat crustaceans.. A food chain is a linear network of links in a food web, often starting with an autotroph (such as grass or algae), also called a producer, and typically ending at an apex predator (such as grizzly bears or killer whales), detritivore (such as earthworms and woodlice ...
