Which is not a sediment transporting agent? a. ice b. a flooding river c. lava flow d. a stream

Lava flow

Explanation: The sediments are carried away naturally by many agents such as water, ice, streams, lakes , river, et cetera.

Sediments are carried away from one place to another which is required for its movement for the formation of soil, to be available at the places where it is required to be.

The lava flow does not carries sediments from one place to another as it is very dense and it cannot carry sediments along with it.

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
