Energy pyramids is representation of food chain where producers lie at the base of pyramid followed by primary, secondary and tertiary consumer. A tertiary consumer lies at the top of the energy pyramid .

An ecological pyramid is a chronological arrangement of organism in which the organism producing the food lies at the base of pyramid and remaining all organism lie above it.
Each level of an ecological pyramid is called a trophic level and an organism lying at any trophic level feed upon organism lying in trophic level prior to it.

Erosion is the process of eroding or being eroded by wind, water, or other natural agents. Erosion can dissolve rock, weakening it or turning it into tiny fragments. Deposition is the process by which sediments settles out of the water or wind that is carrying it, and is deposited in a new location. <span>Deposition transports previously eroded sediments, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment. </span>
