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.
Sand dunes have loose and shifting particles that cannot support your weight evenly. When you walk on sand dunes, the grains of sand move and shift beneath your feet, causing you to sink. This sinking occurs because your weight presses down on the sand, causing it to compact and displace outwards.
Carbohydrates are the macromolecules ingested by animals that are broken down into glucose during digestion. Glucose is a simple sugar that is used as a primary source of energy for cellular processes in the body.
The chamber in the digestive tract of grazing mammals where cellulose is broken down is called the rumen. It is a specialized stomach compartment where bacteria and other microorganisms help digest cellulose by fermentation.

corn....and sand
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.
Erosion/gathering which generates 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.
Rocks being broken down into soil and sand is a natural process called weathering. Weathering involves the physical, chemical, and biological processes that break down rock into smaller particles over time. This process is important for soil formation and nutrient cycling in ecosystems.
When it rains, the limestone of the Yucatan Peninsula gets broken down into sand.

Sand dunes
Sand does not regenerate itself. It is constantly being broken down from larger rocks or minerals through weathering and erosion processes, but it does not have the ability to actively regenerate.
Boulders broken down by weathering or erosion can form smaller pieces called pebbles or gravel. These smaller pieces can eventually be further weathered into sand particles.
