Complete answer:
Biological diversity also known and biodiversity refers to all the various life forms that exist on earth. It has different levels namely species, genetics and ecosystem. Species diversity refers to the number of different species on earth as a whole.
Genetic diversity refers to variation in the genetic makeup of the organisms. Ecosystem diversity refers to various ecological interactions on earth. Life forms vary in the genetic composition. They vary in size. The life forms have various habitats — land, water, air. Some organisms feed on their own and some live on a host for survival. Some organisms divide sexually and some asexually. Some species are unisexual and some are bisexual.
The range of variations in different life forms commonly seen are—
Variation in size — this comparison can be seen between a bacteria and blue whales. Bacteria are so small in size that they can only be seen under a microscope whereas the blue whale is about 50 m long. It can also be compared to giant red wood trees in the forests of California.
 Variation in life span — life span in species can be between a few hours to hundred years.
Insects for eg fruit flies live only for a few hours, mosquitoes die within few days, pine trees live for several years and turtles live for 100 years
Variation in colors — the colors of all the animals have a huge variety. The worms appear to be colorless whereas birds, butterflies and flowers have a variety of bright colors.
