Abstract
Anuran tadpoles are gregarious in nature and knowledge of food and feeding behavior of the tadpoles is very essential for their successful breeding and survival. Dramatic declines in amphibian populations have been noted since 1980 from all over the world and are thus perceived to be one of the most critical threats to global biodiversity. Microhyla ornata commonly known as Ornamented Pygmy Frog, belongs to Family- Microhylidae and is widespread species occurring throughout South Asian countries like Bangladesh, India, Myanmar, Pakistan, Sri Lanka as well as in Japan. Considering the occurrence of tea plantation in the region and the presence of aquatic bodies in tea estates it is necessary to know the feeding habit of the anuran tadpoles and impact of unavailability of suitable food items which will affect the survival and completion of life cycle of the tadpoles. In the present study it was observed that Microhyla ornata tadpoles feed mainly on various algal (25 genera) and detrital material. Hence, it may be concluded that aquatic habitats must be conserved and maintained so that conservation of anurans can be ensured.

The present study describes the qualitative and quantitative analysis of food consumed by the tadpoles of Microhyla ornata from a tea estate
The degree of dominance of food items in stomach sample was calculated by Berger- Parker Diversity Index which is as follows: D=Nmax/ N where, N= the total no. of individuals & Nmax= the no. of individual in the most abundant resource
