passive transport and active transport.
active
Carrier proteins are sometimes used during passive transport.
Raw materials are the natural elements you find on Earth. For example, timber, iron, gold, fish, aluminum, and things of that nature. The transport market is where you transport these materials to a plant or factory to be processed. It is all about where you place this factory. For example, if you were turning timber into paper, you would probably locate the plant near the raw material.
active transport requires input of energy as it takes place aginst a gradient.

The place that a piece of timber was grown can affect its strength and durability. For example, Western Red cedar grown in places with warmer winters grows quickly, so it can have less durability than that from areas with cold winters. Also, there are different forest or plantation management procedures in different locations, and this and transport methods and distances affect the sustainability of the timber. If this is a concern you will need to research the location, the transport used and the practices in use there. There are sustainability certifications for timber that reduce the research you need to do. Check with government agencies as to which certifications are reliable.

In many ways, firstly for grain quality. Age, type of timber, dampness/dryness

The timber is not different but it comes from sustainable sources. So in theory it does not reduce the amount of forest cover. Some people would argue that the distinction is spurious.

there are lots of techniques by which we can improve the life of a timber like seasoning of timber,by applying different types preservatives coat before it is used.
i think it was because of the people for the wars and that they could transport grain and timber there and store it there
