EVERYDAY SCIENCE

Detailed explanation-1: -Preserved evidence of the body parts of ancient animals, plants and other life forms are called ‘body fossils’. ‘Trace fossils’ are the evidence left by organisms in sediment, such as footprints, burrows and plant roots.

Detailed explanation-2: -Fossils are the remains of plants, animals, fungi, bacteria, and single-celled living things that have been replaced by rock material or impressions of organisms preserved in rock.

Detailed explanation-3: -Almost all fossils are preserved in sedimentary rock. Organisms that live in topographically low places (such as lakes or ocean basins) have the best chance of being preserved. This is because they are already in locations where sediment is likely to bury them and shelter them from scavengers and decay.
