Primary succession is a method of fertilizing soil that was barren and had never supported plant life, for example soil left over by a moved glacier of lava.
The soil is first "normalized", using pioneer species such as lichens, algae and fungi.
After this, plants able to survive in less harsh conditions such as grasses.
Therefore, the fertility of soil during early years of primary succession does not increase much and it is a process that involves a long period of time.
Tracers are defined as elements
that can be monitored through biochemical reactions. This characteristic of tracers makes
them useful for the exploration of the mechanism of chemical reactions by
tracing the path that the they follow from reactants to products. A good
number of complex biochemical reactions (e.g. photosynthesis) have been studied
using tracers.
Answer:
energy?
Chemical energy of a chemical substance can be transformed to other forms of energy by specific chemical reactions. For example, when a fuel is burned, the chemical energy is converted to heat energy. When digested food is metabolized within in a biological organism, chemical energy is also converted into heat energy.
