The main layers are epidermis and Dermis
The order of skin layers from outermost to innermost is the epidermis, dermis, and subcutaneous tissue (also known as the hypodermis). Each layer plays a unique role in protecting the body, regulating temperature, and providing structure and support.
The chemistry of the material in the layers.
Phytoplankton are the autotrophs that are the main producers for the upper layers of the ocean.This is because the upper layers of the ocean provide the most sunlight, which is what phytoplankton need in order to perform photosynthesis.
The three main layers that make up Earth is:CORE, MANTLE, and the CRUST

Cnidaria are diploblastic animals, in other words they have two main cell layers, while more complex animals are triploblasts having three main layers. The two main cell layers of cnidarians form epithelia that are mostly one cell thick.
