The correct answer is option b. Carolus Linnaeus. 
The binomial nomenclature also known as binary nomenclature refers to a general system of naming species of living things by providing each a name comprising of two parts, in this Latin grammatical words are used. 
Such a name is known as a binomial name or a scientific name. The initial part of the name demonstrates the genus to which belongs the genus, while the second part; the specific name demonstrates the species within the genus. 
 
        
                    
             
        
        
        
An igneous rock can be formed from cooled magma. The igneous rock can become sedimentary if it is broken down by wind or water. The sedimentary rock can become metamorphic if it becomes buried in the earth, where pressure and heat would turn it into a metamorphic rock. The metamorphic rock can then become an igneous rock by melting underground and turning into magma, flowing out of a volcano, and cooling.

The biome that has infertile soil, principally oxisols, to which the vegetation <span>has roots systems that capture nutrients from litter decay, is the tropical rainforest.
Soil types are highly variable in the tropics and are the result of a combination of several elements or variables which includes climate, vegetation, topographic position, parent material and also the soil age. Most of the tropical soils are described by leaching and poor nutrients. It also has two classifications: namely the ultisols and oxisols. Ultisols are known as well-weathered, acidic red clays soils. They are deficient primarily in major nutrients such as potassium and calcium. Oxisols are also an acidic type of tropical soil. However, they are well drained compared to the ultisols.
