Many farms and ranches use reservoirs, like the one shown here, to collect and store rainwater. Reservoirs ensure there is enough water for crops and animals. Describe the type of soil that would be best for lining up a reservoir. Reservoirs need to hold water. For this reason, they should be lined with soils that have and because . (Discuss permeability and porosity in your response.)

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg 

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
