The right answer is non rebreather.
A non-rebreather mask (NRB) is mainly used to provide oxygen to treat hypoxia, in which arterial blood oxygen saturation is less than 90 percent.
Non-rebreather masks offer an increased level of moisture towards the nasal passage, which can become inflamed and irritated with prolonged oxygen treatment. Increased humidity also increases the patient's respiratory secretions.

Answer:
1. The primary way that fungi reproduce and spread their species on Earth is through spores. These spores are carried by the wind or by other organisms.
2. The role of mycorrhizae in plants is that they live in the roots of plants and turn unusable matter into minerals and water for the plants. The plants also provide energy and a place for the mycorrhiza to live.
3. The three main substances that fungi convert into usable forms for other organisms are phosphorus, nitrogen, and carbon.
4. Fungi break down organic matter and convert it into usable nutrients.
5. It's helpful that fungi attack and kill other organisms that are parasitic because these parasitic organisms can wreak havoc on the ecosystem. The fungi help to protect other species and populations by controlling and curbing the growth of the parasitic organism.
