Which type of sedimentary rock forms from weathered sediment?

chemical
clastic
coal
organic

The correct option is clastic

Clastic sedimentary rocks are made up of small pieces known as clasts of pre existing rocks. These pieces of rocks are loosened by weathering process and then moved to some basin or depression where sediment is placed. If the sediment is buried deeply under ground, it becomes hard, compacted and cemented which results in the formation of sedimentary rock.

d is the answer

sorry if its wrong!

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
