A population estimate is a calculation of the size of a population for a year between census periods or for the current year.
These mushrooms and other fungi will be classified as decomposers and they will obtain their nutrition by breaking down the body of organisms that have died. These organisms play a vital role in the cycling of nutrients in a food chain, since they convert the macromolecules present in dead organisms into smaller ones and release them back into the environment.

- The pathogen cultivated must cause sickness when it's injected in suceptible inviduals.
- The pathogen must be isolated from the injected individuals and must be exactly as the first one.
If there is an increase in orbital radius, this would also increase the average orbital speed or the velocity.
The orbital radius and the orbital speed is directly proportional. When the radius is increased, the orbital speed will also increase but it has to add energy to the system to increase the orbital radius.
