Sonoran dessert and the intruders

it is usually about non-native (invasive) species entering the Sonoran Desert ecosystem.

The Sonoran Desert is a large desert that stretches across parts of Arizona, California, Sonora (Mexico), and Baja California. It is home to unique plants and animals such as saguaro cacti, coyotes, roadrunners, and Gila monsters.

Who are the intruders?"Intruders" are usually invasive species—plants or animals that do not naturally belong in the Sonoran Desert but have been introduced there.

Examples include:

  • Buffalo grass – an invasive grass that spreads quickly and increases the risk of wildfires.

  • Red brome – another invasive grass that competes with native plants.

Reduction

Reduction

At the same time of oxidation, an atom of magnesium oxide, water, and a free electron combine to form a slightly different version of magnesium oxide.

This means it no longer needs hydroxide atoms, so it ejects it.


This type of reaction is called reduction.

Oxidation reduction

Oxidation and reduction are opposite processes that always happen together, so they are called redox reactions. Oxidation is the loss of electrons, while reduction is the gain of electrons. A simple way to remember this is OIL RIG — Oxidation Is Loss, Reduction Is Gain. In a redox reaction, the substance that loses electrons is oxidized, and the substance that gains electrons is reduced. For example, when zinc reacts with copper ions, zinc loses electrons and becomes Zn²⁺, while Cu²⁺ gains those electrons and becomes copper. The substance that causes another substance to be oxidized is called the reducing agent, while the substance that causes another substance to be reduced is called the oxidizing agent. Oxidation can also be described as gaining oxygen or losing hydrogen, while reduction can mean losing oxygen or gaining hydrogen. Redox reactions are important in rusting, burning, batteries, respiration, photosynthesis, metal extraction, and many chemical…

What is oxidation

In oxidation reaction, oxidation release electrons, which is very helpful.


hydrogen ion from the electrolyte combines with a zinc atom, forming zinc hydroxide.


Hydrogen ion and electrolysis combined with zinc equals zinc hydroxide.


This is oxidation.


This release electrons, electrons stored in a brass.
