Question

how might an entire insect be preserved?
soft and hard tissues turn the insect into rock.
tree sap flows over the insect and hardens.
sediment accumulates over the insect and hardens.
carbon from the decaying insect leaves a print on a rock.

Explanation:

When tree sap flows over an insect and hardens, it creates amber which can preserve the entire insect intact. Soft and hard - tissues turning into rock is a long - term fossilization process that typically doesn't preserve the whole insect well. Sediment accumulation usually leads to compression and distortion. Carbon leaving a print on a rock is a type of fossilization but doesn't preserve the whole insect.

Answer:

Tree sap flows over the insect and hardens.
