Why do scientists study seismographs? o to learn about different rock samples
o to determine the location of an epicenter
o to analyze mineral content from Earth’s crust
o to observe temperature changes on Earth’s surface

Explanation:

When there is an earthquake, everything in the seismograph moves except the weight with the pen on it. ..This record made by the seismograph is called a seismogram. By studying the seismogram, the seismologist can tell how far away the earthquake was and how strong it was.

meteorologists would compare a new weather map with one 24 h old to see how fast a front is moving.

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
