In the context of environmental science and biology, various types of conservation methods are applied to protect species. One key type is taking threatened species out of their natural habitat and placing them in special settings. This process involves:
Based upon these descriptors, this type of conservation is known as Biodiversity conservation. This approach focuses on maintaining and restoring varied forms of life and ensuring they are conserved ex-situ, that is, outside their natural habitats.
Study the pie chart given below, representing the global biodiversity and proportionate number of species of major taxa.
Answer the following questions:
[a] Identify 'X' and 'Y' in the given pie chart.
[b] Which one of the two 'X' or 'Y' is the most species-rich taxonomic group and by what percentage?
[c] Name the level of Biodiversity represented by the following:
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 :
