Use the balanced equation of a nitrogen cycle pathway below to support the conservation of matter and energy.
Nastasia [14]

Law of thermodynamics states that matter and energy cannot be destroyed or created, but can be converted from one form to another. A balanced equation ensures that this basic principle is observed.

On the left-hand side of the equation (the reactants), there are 2 Nitrogen moles and 8 Hydrogen moles. After the reaction, the molecules are rearranged. Nonetheless, the moles of Nitrogen and Hydrogen in the products remain the same.

inysia [295]

Answer:

Allopatric speciation

Explanation:

Speciation is the gradual process by which two different species are formed from a single species due to evolution.

Allopatric speciation will occur when the speciation is due to geographical isolation of a species to the extend it prevents or interferes with the gene flow. Therefore, the populations can not mate with each other and they evolve separately.

This is what happened to the fox species when they were separated by a mountain range.
