6) When pathogenic fungi are found growing on the roots of grape vines,
grape farmers sometimes respond by covering the ground around their vines
with plastic sheeting and pumping a gaseous fungicide into the soil. An
important concern of viticulturists who engage in this practice should be that
the
A) lichens growing on the vines' branches are not harmed.
B) fungicide doesn't also kill mycorrhizae.
C) fungicide doesn't also kill the native yeasts residing on the surfaces of
thegrapes.
D) fungicide isn't also harmful to insect pests.
E) sheeting is transparent so that photosynthesis can continue.

7) How are the vascular plants that are involved in mycorrhizae and the
algae that are involved in lichens alike?
A) They secrete acids that keep the fungal partner from growing too quickly
.B) They are digested by fungal exoenzymes while still alive.
C) They contain endosymbiotic fungi.
D) They are in intimate associations with chytrids.
E) They provide organic nutrients to fungal partners.

animal heterotrophy from fungal heterotrophy is that only animals derive
their nutrition
A) from organic matter.
B) by ingesting it.
C) by consuming living, rather than dead, prey.
