Question

Ornithology is study of
A. Birds
B. Lizards
C. Bryophytes
D. Pollen grains

Answer 1

This subject deals with the study of those organisms which have adaptations for aerial habitat. They have hollow bones and forelimbs modified into wings. They are next to reptiles in evolutionary timescale.

Complete answer:
If we look at option A which is Birds, It is the correct answer because the study of birds is known as ornithology. It is a branch of zoology which deals with study and knowledge of birds. Therefore, this option is correct.
Moving to option B which is Lizards, Lizards belong to reptiles and study of reptiles is not called ornithology. Study of reptiles and amphibians is called Herpetology. Therefore, this option is incorrect and hence it gets eliminated.
Moving to option C which is Bryophytes. As the name suggests, their study is known as Bryology. Birds are not bryophytes therefore their study is not called as biology and it gets eliminated because it is an incorrect answer.
Last option is D which is Pollen grains. Study of pollen grains is Palynology and therefore this option is also incorrect and it gets eliminated.

Thus, the correct answer is option A which is Birds.

Additional information:
Studies on birds helped to develop key concepts in biology which includes evolution, behaviour and ecology. It has helped to understand the definition of species, the process of speciation, learning, ecological niches, island biogeography, conservation, etc. But early ornithology was only concerned with distributions of species. Ornithologists study the behaviour, physiology and conservation of birds and their habitats. Sálim Moizuddin Abdul Ali is the father of ornithology.

Note: It is a branch of zoology which deals with study and knowledge of birds and from all the above options the study of them is known as Bryology for Bryophytes, Palynology for pollen grains, Herpetology for reptiles and amphibians therefore the correct option is birds.
