That would be ascomycota or sac fungi. Sac fungi are characteristically known for producing ascus. This is a sac-like structure that contains haploid spores called ascospores. Some examples of sac fungi are yeast, truffles, morels and dead man's fingers.
I agree because an ecosystem and a host are basically the same thing.
Answer:
Absolute Zero
Explanation:
It is based on molecular motion, with the temperature of 0K, also known as absolute zero, being the point where all molecular motion ceases. The freezing point of water on the Kelvin scale is 273.15K, while the boiling point is 373.15K
It wouldn't be 0 degrees C or 0 degrees F because the temp of the molecular motion stop in Celsius is -273.15 degrees and in Fahrenheit it would be -459.67 degrees.
I hope this helps :)
