Give 5 examples of an ecosystem
Some examples of man-made shell structures include the Sydney Opera House in Australia, the Eden Project in the UK, and the Pantheon in Rome. These structures utilize the strength and efficiency of shell-shaped designs to create large, open spaces without the need for internal supports.

FRAME STRUCTURESFrame structures are structures that are made up of rigid (stiff, firm, difficult to bend) parts joined together to form something called a framework. These parts are known as members. There are lots of examples of frame structures such as a bridge - a bridge is a frame structure that spans a gap, and a bicycle is a frame structure that supports a load such as the mass of a person.SHELL STRUCTURESShell structures contain or protect things from the outside and are usually hollow inside. In a shell structure, the outside layer of the structure holds the whole object together. Examples of shell structures are the mug that holds your coffee, the snail shell which both protects and contains the snail, honeycomb which contains and protects bee's honey and shells of nuts.
give me the answer, and ill tell you if its right :) improved answer: some examples are a dam, a brick wall, Egyptian pyramids, mountains etc.
chairs are shell/solid structures because it is a solid and can be considered a frame
