The parasitic adaptations in Taenia have taken place along: 1. Degeneration or loss of organs 2. Attainment of new organs.

Write a short note on Adaptation
Adaptation is the characteristic of living organisms. It includes structural and functional features which improve their chances of survival in the environment in which they live. An organism which copes well with a particular environment leads a better life and breeds more successfully than the one which does not do so.
Notes on the phenomenon of Adaptation in Aquatic Habitat
Aquatic habitats may be either freshwater like lakes, ponds, rivers, spring or saline (salt water) like oceans. A wide variety of organisms lives in these habitats. Sudden change in water temperature is not observed because water absorbs and loses heat gradually.
Write a short note on Land Habitat and adaptation
Organisms living on land are subject to a variety of physical factors. These are temperature, humidity, soil, etc. light, temperature, rainfall, etc., are considered climatic factors while properties and nature of soil are known as edaphic factors.
How does adaptation occur in Plants ?
The plants which require moderate amount of water (mesic conditions) are known as mesophytic plants. The soil in which they grow is neither very wet nor dry. These plants are usually found in the plants and gardens. Rose, peepal, mango, sunflower, goldmohur, etc. are common examples of mesophytic plants.
Understanding the phenomenon of Nutritional Adaptation in Plants
The plants are grouped into two major categories based on their ability to prepare or obtain food. Autotrophic plants include green plants which can prepare their own food and can live independently. From inorganic raw materials, like carbon dioxide and water they can photosynthesize with the help of chlorophyll pigments in the presence of sunlight.
How does Terrestrial Adaptation occur in Animals ?
Terrestrial animals usually show adaption in relation to (i) locomotion in a particular environment, (ii) protection and (iii) feeding habits. All fast- moving animals have streamlined bodies this is for reducing the resistance to the environment (air, Water, land) as much as possible.
How does adaptation occur in Desert animals?
Desert animals are adapted in such a way that they can withstand heat and water scarcity. Desert rats and snakes dig holes and burrows in the sand and live inside them during daytime. At nigh when the surroundings get cooler, they come out in search of food, and are, therefore, nocturnal in habit.
How does adaptation occur in the Polar-region?
Polar Regions are characterized by extreme cold and long snowy winters. Organisms living here have to adapt themselves to extreme cold. The animals in these regions are usually white or light colored, e.g., polar bear, penguin.
