In your own words explain why Fossil is not complete?

Fossil is not complete because it represents only a fragment of the entire history of life on Earth. The fossil record is inherently biased, as conditions for fossilization are rare and typically favor organisms with hard parts, like bones and shells. Additionally, many species existed for short periods or lived in environments that did not support fossilization, resulting in gaps. Consequently, while fossils provide valuable insights, they cannot capture the full diversity and evolution of life.
