Answer :
The classification of the following descriptions and examples is both keystone and flagship species. Hence the correct option is c.
A species classified as both a keystone and a flagship species plays a dual role in ecological significance and conservation emphasis. Keystone species have a disproportionately large impact on their ecosystem, influencing its structure and function. Flagship species, on the other hand, serve as charismatic representatives for conservation efforts, capturing public attention and support.
When a species embodies characteristics of both, it not only holds ecological importance in shaping its environment (keystone) but also acts as a symbol for broader conservation initiatives, garnering public interest and support (flagship). This dual classification underscores the species' pivotal role in both ecological and conservation contexts, emphasizing its crucial significance for maintaining ecosystem health and promoting environmental awareness. Hence the correct option is c.
