What is the difference between the abiotic and biotic factors of an ecosystem? Give an example. Describe five biotic and abiotic processes on this planet that cause adaptive radiation (speciation) to take place and the environment in which each occu...
The acquisition of photosynthesis is a fundamental step in the evolution of eukaryotes. However, few phototrophic organisms are unambiguously recognized in the Precambrian record. The in situ detection of metabolic byproducts in individual microfossils i
The scope of their work is huge, covering oceans, forests, wildlife, fresh water, climate and food. They support some of the most endangered animals today – giant pandas, tigers, elephants, gorillas, sea turtles, polar bears, rhinos and whales.A huge thanks to all of these top ...
the proximity of the supermoon can have a direct effect on the Earth, specifically with the tides. Tides are caused by the gravitational interplay of the sun and moon on Earth's oceans. The tides are highest during a new and a full moon, and...
There are at least 800 different living species of Cephalopods. Two important extinct taxa are the Ammonites, and the Belemnites (orderBelemnoidea, of class Coleoidea). Cephalopods are found in all theoceansof the world and at all pelagic levels. None of them can live in freshwater (water...
What is the ecological importance of nematodes? Why is it difficult to protect marine biodiversity? What are three ways in which we could try to protect marine biodiversity? Describe two benefits that terrestrial ecosystems provide for oceans. Describe an ecosystem and all the parts included. Why ...
This agrees with the early occurrence of sulfate reducers in the geological record as inferred from published microscopic pyrite data, and identifies their role as important in both global oceans and local basins in the Paleoarchean.doi:10.1016/j.epsl.2012.03.020Desiree L. Roerdink...
the perspective of the supercooled droplets, the air is in equilibrium at saturation, but from the perspective of the ice crystals, the air is supersaturated. Therefore, water vapor will sublimate on the ice crystals. Since the amount of water vapor in the air has decreased, and from the ...
