Habitat is the term given to the special environment in which an organism lives and grows. In order to survive, plants and animals develop special features called adaptive characters that help them to adjust to a particular habitat. This is known as adaptation..

These are the adaptations for running and are found in flightless birds such as ostrich, kiwi and many other animal..

The principle of adaptive radiation is based on two evolutionary mechanisms - convergent and divergent evolutions. Divergent evolution involves the homologous structures. A group of organisms modify a common homologous structure to perform different functions. For example, the ..

Two important characteristics of the desert i.e., the scarcity of rainfall and high temperature determine the existence, distribution and adaptations of the animals of the desert. The characteristic animals of the desert are small herbivorous rodents, reptiles and insects. Birds and mamma..

This is an immunity developed by an animal in response to a disease caused by infection of pathogens. It is very specific and prevents further attacks. It lasts for the whole life of the organism in certain cases and for a few years in others. Acquired immunity is further of two types - n..

Each and every living organism has its specific surrounding medium of environment with which it continuously interacts and remains fully adapted. The environment is the sum total of physical and biotic conditions influencing the responses of the organisms. The life sup..

Summary - Ecology concerns with the associations and interactions of the organisms and the environment in general. The living place or dwelling place of an organism is called habitat. Within a given habitat there exists variations or micro habitats. In a given habitat we can obs..

>Living organisms show adaptations to their surrounding environment. Living organisms show the ability to undergo evolution over a period of time. Living organisms exhibit the capacity to respond to a stimulus. This property is called as irritability. Living ..
