Answer: A chemical reaction occurs when some substances change chemically to other substances. Chemical reactions are represented by chemical equations. Consider a simple chemical reaction, the burning of methane. In this reaction, methane (CH4) combines with oxygen (O2) in the air and produces carbon dioxide (CO2) and water vapor (H2O). The reaction is represented by the following chemical equation:

CH4 + 2O2 → CO2 + 2H2O

How do invasive species spread? identify three methods.Why do invasive species pose such a threat?
seropon [69]

Answer:

See the explanation below.

Explanation:

A species is invasive can be spread, naturally either by the behavior of the species, or introduced accidentally or voluntarily by man.

The invasive species increases its density in the occupied area or colonizes new territories over time.

That an invasive species is harmful means that it produces significant changes in the composition, structure or processes of natural or semi-natural ecosystems, endangering native biological diversity.

Uncontrolled reproduction of this invasive species also increases the risk of control and extermination of the species, due to the acclimatization of the new species in the environment as well as possible exponential reproduction.
