Question

Discribe three terrestrial and 2aquatic biomes. Where to do these biomes occur and under what cinditions?

Answer 1

1) Terrestrial Biomes  

a) Tropical Wet Forest--Tropical wet forests are also classified as tropical rainforests. This biome is located in regions of Equator. The vegetation is characterized by plants with large leaves which fall off all year round. Unlike deciduous forest plants, the plants in this ecosystem do not have a seasonal loss of leaves correlated with weather and sunlight variations; these forests remain "evergreen" year-round. Tropical wet forest weather and sunlight levels are very constant relative to other terrestrial biomes, with temperatures varying from 20 ° C to 34 ° C (68°F to 93°F).

b) Savannas---Savannas are grassland with sparse trees in Africa , South America and Northern Australia. The savannas are hot, tropical areas with an average temperature of 24 ° C to 29 ° C (75 ° F to 84 ° F) and 10–40 cm of rain each year. Savannas have a large dry season; for this reason, forest trees do not grow as much as in tropical moist forest (or other plant biomes). There are relatively few trees in the grasses and forbs (herbaceous flowering plants) which dominate the savanna

c) Subtropical Deserts----Subtropical deserts occur between latitude 15 ° and 30 ° north and south, which are based on the Cancer which Capricorn Tropics. This environment is quite dry; evaporation overtakes precipitation in certain years. Subtropical hot deserts will have surface temperatures over 60 ° C ( 140 ° F) throughout the day and temperatures below 0 ° C (32 ° F) at night. Temperatures in cold deserts will rise as high as 25 ° C and fall below -30 ° C (-22 ° F). Subtropical deserts are distinguished by less than 30 cm (12 in.) of low annual precipitation with little monthly variability and lack of predictability of rainfall.

2) Aquatic Biomes

a) Marine Biomes ---The ocean is marine biome of the largest. It is a continuous pool of salt water and in chemical composition is fairly uniform; it is a thin solution of mineral salts and decayed biological content. Coral reefs are a second form of marine ecosystem within the ocean. A third unique marine biome forms estuaries, coastal areas where salt water and freshwater mix together.

b) Freshwater Biomes---Biomes of freshwater include lakes and ponds (standing water), rivers , and streams (flowing water). They do have wetlands that will be discussed later on. In order to provide water resources for drinking water, crop irrigation, sanitation, and industry, humans rely on freshwater biomes. These different roles and benefits for humans are called ecosystem services. Lakes and ponds are located in terrestrial ecosystems, and are thus related to abiotic and biotic factors that affect these terrestrial biomes.
