Detailed explanation-1: -Amber is formed from resin exuded from tree bark (figure 9), although it is also produced in the heartwood. Resin protects trees by blocking gaps in the bark. Once resin covers a gash or break caused by chewing insects, it hardens and forms a seal.

Detailed explanation-2: -Amber is actually made of resin, a different tree goo altogether. While sap is watery and flows through a tree the way blood flows through our veins, resin is thick and just oozes around inside the tree. Its job is to protect the tree from diseases and harmful insects.

Detailed explanation-3: -Hardened tree sap is called amber. Amber is often used in jewelry, and two common sources for amber include the Baltic region and the Dominican Republic. Sometimes, small animals such as insects become trapped in tree sap and are then preserved in the resulting amber.

Detailed explanation-4: -Amber is organic resin or “tree sap”.

Detailed explanation-5: -What do you see? Sticky “sap” flows from the tree, essentially making a bandage over the wound that hardens and eventually fossilizes into an incredibly hard substance called amber.
