<span>During nitrification, ammonia is changed back into nitrate.</span>
Nitrification is a three-step process of oxidation of ammonia. It is an aerobic process performed by small groups of autotrophic bacteria (<span>Nitrosomonas,
Nitrobacter</span>).
First step- ammonia to hydroxylamine,
Second step-hydroxylamine to nitrite,
Third step-nitrite to nitrate.
Nitrification together with ammonification is part of a nitrogen cycle.
The small intestine has cilia to absorb nutrients and reabsorb water
Answer:
Fungi, many birds, and a wide variety of insects all share the <u>bark</u> of a tree in the forest. Part of the <u>hyphae</u> of the fungi is to obtain energy from dead organic matter, such as dead wood. Temperatures above 0°C and sufficient water in the environment help define the range of<u> spore germination</u> for fungi.

Answer:
<em>Entamoeba histolytica</em>
Explanation:
<em>Entamoeba histolytica </em>is the causative agent of amebiasis (amebic dysentery). The pathogen enters the human body through consumption of contaminated water or food and enters the small and large intestines. <em>E. histolytica</em> targets the epithelium of large intestine and creates ulcers in it. <em>E. histolytica </em>enter the mucosa and submucosa of the intestine through these ulcers and leads to severe dysentery, that is amoebic dysentery.
