The size of the pebble will decrease down stream because the further downstream you go the quicker the river velocity. This means there will be more abrasion against the sides and bed of the river and the friction will be greater, this wears away the river load making it decrease in size. Increase velocity means that bigger material will be picked up by the river and carried as river load. More load in the river and increased size of load will mean more attrition and the river load will keep colliding into each other smoothening and rounding their shape.
Brap brap !!
Bedload decreases downstream due to the fact that the rocks and pebbles would be bumping into each other and breaking bits off (abrasion and attrition). Also, faster river velocities are capable of carrying greater amounts of bedload and transporting them farther and faster. The shape of the sediments of the bedload would therefore be exposed to more physical weathering which would progressively round the sediments and also decrease their size.
because the river picks up speed so it is able to erode the bedload better so the river gets less and less bedload.
Usually because the downstream portion of a streambed receives the most flow and therefore more scour and smoothing of the streambed.

How do stream transport sediments?
Stream transport sediment in three ways, dissolved load, (ions in solution being carried downstream), suspended load, (suspended sediment that floats freely downstream) and bed load, (sediment that rolls or scoots along the bottom of the river).
How does the bed load affect the erosion?
Bed load can increase erosion by entraining and transporting sediment along the streambed, causing abrasion and scouring of the channel bed. The movement of sediment in the bed load can also contribute to sediment transportation and deposition in downstream areas, altering the overall balance of sediment in the stream system and potentially leading to changes in channel morphology and erosion patterns.
What is the difference between a rivers suspended load and its bed load?
The difference between a suspended load and a bead load is a suspended load consists of the small particles or rock materials that are dispersed throughout the water and easily carried downstream. The bead load consists of the larger particles that are dragged and bounced along near the bottom of the river.

What and the difference between a rivers suspended load and it and bed load?

The bead load consists of the larger particles that are dragged and bounced along near the bottom of the river.
What is the difference between a river's suspended load and its bed load?
The difference between a suspended load and a bead load is a suspended load consists of the small particles or rock materials that are dispersed throughout the water and easily carried downstream. The bead load consists of the larger particles that are dragged and bounced along near the bottom of the river.
What is the difference between a rivers suspended load and it's bed load?

Particles that roll and slide along the stream bed make up the of the stream?
Bed Load
What is the difference between suspended load and bed load?
Suspended load refers to sediment particles carried in the water column, while bed load refers to sediment particles that are transported along the riverbed through rolling, sliding, or saltating movements. Suspended load is typically finer particles that remain suspended in the water, while bed load is larger particles that move along the riverbed.
What is the difference between a river suspended load and it's bed load?
Suspended load refers to particles carried within the water column of a river, while bed load refers to larger particles that are transported along the riverbed by rolling, sliding, or saltation. Suspended load is typically finer particles like silt and clay, while bed load consists of coarser materials like sand and gravel.
What affects Bed load particle size?
what is bed load particle size
What is the difference between a stream's load and it's bed load?
The suspended load moves with the water, the bed load only moves when the river is in spate.
