Plankton is at the bottom of a food chain. Think of a pond. Mosquito larvae are in a pond. They eat the plankton. Small fish eat the larvae. Larger fish eat those smaller fish and the chain keeps going..BUTTT it all started with the PLANKTON. Without the plankton the whole food chain would be messed up and everything would start dying..

Answer: One type of map uses the cytogenetic location to describe a gene’s position. The cytogenetic location is based on a distinctive pattern of bands created when chromosomes are stained with certain chemicals.

The molecular location is based on the sequence of DNA building blocks (base pairs) that make up the chromosome. Buttt I don’t know if this is the answer your looking for. But I hope this helps in a way.
