Although plants account for more than 90 percent of the earth’s two trillion tons of biomass, they represent only some 20 percent of earth’s classified and named organisms. In contrast, while the animals make up only a small fraction of the biomass, they represent more than 60 percent of...
“a medium sized butterfly, measuring about 3 inches from wingtip to wingtip. Its body is about one inch long. Its four wings are generally a field of yellow, orange or gold, with veins of black running through them. A band of black, thickest at the front, rings the wings, and the ...
How are climate zones classified? How does an area's weather differ from the area's climate? How are biomes classified geographically? What is the coldest climate type within Koppen's climate system? How are terrestrial biomes defined?
How seismic zones are classified? How does an area's weather differ from the area's climate? How many climate zones are there? How are biomes classified geographically? What is a climate zone map? How are forest biomes classified? What are the climate zones in Africa?
Satellite Earth observations (EO) can provide affordable and timely information for assessing crop conditions and food production. Such monitoring systems are essential in Africa, where food insecurity is high and agricultural statistics are sparse. EO-b
Out of the 74 CK chondrites listed in the Meteoritical Bulletin Database (2006; excluded considerably paired specimens; see http://tin.er.usgs.gov/meteor/metbull.php) we analyzed 24 and subclassified the CK chondrites in terms of their chemical composition and sulfide mineralogy: sL (...
As abstract as climate zones may seem, they remain a key tool for understanding earth’s manybiomes, tracking the extent of climate change,determining plant hardiness, and more. The Discovery of Earth’s Climate Zones The concept of climate zones dates back to ancient Greece. In the 6th centu...
[11] The soil is classified as an Auburn very rocky silt loam (lithic haploxerepts). It contains 43% sand, 43% silt, and 13% clay. Its bulk density at surface layer (0–30 cm) is around 1.61 ± 0.10 g cm−3 (n = 54). Total nitrogen and carbon content of the soil are ∼...
What is the function of fire in grassland and mountain forest biomes? How have protists traditionally been classified? What are the main types of natural disturbances that influence: 1) forests? 2) grasslands? How does climate influence a biome, and what are some of the factors that determine...
Why are aquatic ecosystems classified differently than terrestrial biomes? Explain how the three major types of deserts differ in their climate and vegetation. Explain why rainforests are often found along the equator while deserts are often found in the subtropical regions. What are so...
