Answer the following questions based on environmental conservation and biodiversity :(a) Complete the flow chart :[Flow chart: a box labelled ‘Classification of threatened species’ with arrows going down to four empty boxes.]

Answer: Classification of threatened species — (1) Endangered species, (2) Rare species, (3) Vulnerable species, (4) Indeterminate species.

• Endangered species: their number has declined or habitat has shrunk so much that they may become extinct in the near future unless conservation measures are taken, e.g. lion-tailed monkey, lesser florican.
• Rare species: their number has declined considerably; being endemic they may become extinct very fast, e.g. red panda, musk deer.
• Vulnerable species: their number is extremely low and continues to decline, e.g. tiger, lion.
• Indeterminate species: they appear to be endangered, but due to some behavioural habits (like shyness) there is no definite information about them, e.g. giant squirrel (Shekru).
