There are different types of ecosystems like the aquatic ecosystem, terrestrial ecosystem etc. aquatic ecosystem is further classified as the pond ecosystem, lake ecosystem, river ecosystem, ecosystem of the aquarium etc. Anyway the pond ecosystem is the ecosystem which is formed in a pond by the living organisms of the pond and the non-living components of the pond like light, heat, temperature, soil water etc. The living organisms of the pond are also known as the biotic factors which are the plants and animals of the pond. Plants are green in color and known as producers. Animals are known as consumers.There are small and microscopic organisms in the pond which are bacteria, viruses and fungi. They are known as decomposers.

PTERODACTYLE

What is pterodactyle? It is also known as flying fox. It is more or less like the fox in appearance but it is unlike the fox because a fox can no more fly but what it amazing with the Pterodactyle is that it is the flying mammal which can fly but not with its true wing but with its patagia or wing like structures. Pterodactyles are the fruit -eating bats. They are seen hanging over the branches of the trees with head in downward position. Due to their capacity to fly in the air although the flight is of not so long distance, they are known as flying fox. They show the general characters of mammals like hair covered body, a pair of pinnae for collecting sound waves, pentadactyle limbs, four-chambered heart, viviparity i.e. giving birth to young ones and warmbloodedness. There are two different types of bats, one type are the insectivorous bats which are of small size in comparison to the pterodactyle. But the large sized bats are frugivorous in nature.

FLYING FISH

Flying Fish coloring pageWhat is flying fish? is it really a fish or some other objects? It is a very interesting thing to know what actually is a flying fish. Of course, there are fishes which although seems impossible to fly, can fly  to some distance above the surface of water.
Flying fish is a fish which is perfectly aquatic in habitat and perfectly adapted to live in aquatic habitat. They have stream-lined body, scale-covered body surface, gills for respiration and fins for locomotion in the aquatic habitat. But what about their flight ? They have a pair of enlarged pectoral fins which are parachute like and help the fish to glide in air for some time just after they lift the body from the surface of water. What helps to lift  their body from the surface of water? They have hypobatic type of tail fin which help to lift the body forward and propel them so that they can glide easily in the air above the surface of water. Due to these properties flying fish which actually is the bony fish is called the flying gish. But their flight is not as efficient as the flight of the birds. As their flight is not based on the muscular pectoral fins but just supported by cutaneous structures called patagia.
