Decomposition

At the global scale, across regions with variable precipitation, which climate variable is likely to be the best correlated with plant litter mass loss rates during the first year of decomposition?

• actual evapotranspiration rates

• precipitation

• potential evapotranspiration rates

• soil temperature

Days 4-10, production of gas, body swelling, greenish tint to body

• fresh stage

• bloat

• active decay

• advanced decay

Days 10-20, loss in mass, fluids leak from body, body starts to disintegrate

• fresh stage

• bloat stage

• active decay

• dry decay

Days 20-50, less insect activity, body dries out, area of body touching ground starts to grow mold

• Fresh Stage

• Bloat Stage

• Active Decay

• Advanced Decay

A body is found with blistering skin that is slipping off of the muscle underneath. There is a strong odor and maggots are seen covering the body. Which stage of decomposition is this body in?

• bloating (putrefaction)

• advanced decay

• active decay (black putrefaction)

• fresh (initial)

the spontaneous breakdown of cells as they self-digest

• rigor mortis

• algor mortis

• pupa/pupae

• autolysis

Match description with the correct stage of decomposition:
livor, rigor, and algor mortis occur during this stage

• fresh

• bloat

• active decay

• advanced decay

post-mortem examination

• adipocere

• autolysis

• autopsy

• entomology
