Question 1

what factors affect decomposition

Answer 1

oxygen availability, pH level, water content, temperature, toxic materials

Question 2

many decomposers need oxygen for _______ respiration so the rate of decomposition ___________ when there is _______ of _______ available.
when there are ____ _______ levels, the rate of decomp is _______. some decomps can respire ____________ but this transfers _______ ________ so these decomps work _______

Answer 2

oxygen, aerobic, increases, plenty, oxygen,
low oxygen, slower, anaerobically, less energy, slowly

Question 3

most decoms work best in low conditions, the rate is highest at ____ as decomps contain ______ which _______ the dead/waste material. The _____ of ________ controlled reaction ______ with temp. at lower temp, rate of ________ is slower, above certain temps, enzymes become ___________ and the reaction ______.

Answer 3

low, 50 degrees, enzymes, digest, rate, enzyme, varies, reaction, denatured, stops

Question 4

most decomps arent able to survive and ____ on material that is very ______ or _________ as _________ become denatured if the ____ is too low or too high.
the rate of decomp will be highest at its _______ pH of the decomposers

Answer 4

grow, acidic, alkaline, pH, optimum

Question 5

decomps need water to survive so the rate of decomp __________ in moist conditons. however, __________ soil dont contain much _______ which many decomps need to _______ so the rate _________ if there is ____ _____ ________

Answer 5

water, increases, moist, waterlogged, oxygen, survive, decreases, too much water.

Question 6

many heavy metals ( m________, a______, l____) are ______ to most organisms. if the ___________ of any of these heavy metals is too _____, very few decomps will be able to _______. therefore the rate of decomp will be ____

Answer 6

heavy metals, mercury, arsenic, lead, toxic, concentration, high, survive, low
