The answer sort of depends on whether you are considering elemental particles or composite particles.
Composite particles are, by their nature, made up from smaller particles. Example of such particles would be an atom (made up from neutron, protons and electrons), protons (made up from quarks) or even mesons (also made up from quarks).
Composite particles can 'break down' into their constituents via interactions; for example in nuclear fission uranium atoms are broken down into smaller atoms.
Elementary particles do not consist of smaller particles; they are the elementary building blocks which make up all other particles. As such elementary particles cannot break down into their constituents.
Elementary particles can however change into other (multiple) particles via decay. For example a muon can decay into an electron, a muon neutrino and an anti electron neutrino. This does not mean the muon consists of these three particles; other decays are also possible.
It is broken down the same way larger rocks are, by erosion and weathering.

Thyrosin is a breakdown product of the thyroid hormones. It can be itself broken down into Norepinephrine.

weathering
Sand is composed of bits of rock that have been broken down to a small size.
Often found in sand is broken down rock particles and dead organisms.
MOST sand consists of broken down rock (silica dioxide). However, on islands, such as Hawaii, most sand is broken down coral (calcium carbonate). This is why most beaches in Hawaii are tan colored, and not white.
yes
Erosion/gathering which generates sand.
tiny broken down pieces of rock and sea shells
sand.
Erosion is the main force that acts on rocks to break them down into sand. Water getting into cracks, freezing and expanding also helps to break down rocks.
Sand is rock or coral that has been broken down by weathering or mechanical means to a fine grain size.
