The question asks to identify the region in India where the Great Indian Hornbill is most likely found in its natural habitat. This requires knowledge of the natural distribution and habitat preferences of this specific bird species.
D) Western Ghats — The Western Ghats are a biodiversity hotspot characterized by dense evergreen and moist deciduous forests, which are the primary natural habitat for the Great Indian Hornbill. These forests provide the necessary large trees for nesting and a rich food source of fruits.
The question asks for the definition of "species evenness." Species evenness is a key component of biodiversity, alongside species richness. It refers to how close in numbers each species in an environment is.
Correct Option: C) Proportion of species at a site. This option correctly defines species evenness as the relative abundance or distribution of individuals among the different species present in a particular location.
The question asks us to identify the correct statements regarding 'The Economics of Ecosystems and Biodiversity (TEEB)' initiative. We need to evaluate each statement based on our knowledge of TEEB's objectives, hosting organizations, and approach.
C) 2 and 3 only
Statements 2 and 3 accurately describe the 'The Economics of Ecosystems and Biodiversity (TEEB)' initiative. TEEB is a global initiative focused on the economic benefits of biodiversity and provides an approach for decision-makers to recognize, demonstrate, and capture the value of ecosystems and biodiversity.
The question asks for the main objective of the 'seed village concept'. This concept is a government initiative aimed at improving seed availability and quality in agricultural communities. We need to identify the option that best reflects this primary goal.
B) Involving the farmers for training in quality seed production and thereby to make available quality seed to others at appropriate time and affordable cost. This option accurately describes the multi-faceted objective of the seed village concept, which includes farmer training, quality seed production, and ensuring accessibility and affordability of seeds within the community.
The question asks to identify the type of diversity that refers to the diversity within a specific area or ecosystem. This is a direct definition question related to ecological diversity concepts.
Correct Option: A) Alpha diversity refers to the diversity within a particular area or ecosystem. It is a measure of species richness and evenness within a single habitat.
The question asks about the definition of Beta diversity. To answer this, we need to understand the different types of biodiversity, specifically Alpha, Beta, and Gamma diversity, and distinguish between them.
C) Change in species between ecosystems
This option accurately describes Beta diversity. Beta diversity quantifies the species turnover or the difference in species composition when comparing two different habitats or ecosystems. It reflects how many species are unique to each ecosystem or how much species composition changes across a landscape.
