In the classification of fungi, several criteria are utilized to categorize different species. These include:
In contrast, the mode of nutrition is not a primary criterion for the classification of fungi. This is because fungi typically have a consistent mode of nutrition, being heterotrophic organisms that absorb nutrients from external sources. Therefore, the correct answer here is Mode of nutrition.
A bob of heavy mass \(m\) is suspended by a light string of length \(l\). The bob is given a horizontal velocity \(v_0\) as shown in figure. If the string gets slack at some point P making an angle \( \theta \) from the horizontal, the ratio of the speed \(v\) of the bob at point P to its initial speed \(v_0\) is :
