23. from top to bottom, what sequence labels would you 1 point
drag into the boxes to show the sequence of events of
eutrophication? *
ecosystem impact from runoff
oxygen depletion, also known as
hypoxia, is one result of runoff from
over-fertilized lawns or farmland.
after heavy rains, nutrient-rich
water enters the local aquatic
environment, cousing a series of
events to occur within the
ecosystem.
some events caused by
nutrient-rich runoff entering a lake
ecosystem are shown.
decomposers increase oxygen consumption
algae consume the available nutrients and
then begin to die oft.
move the sequence labels into the
blank boxes to sequence the
correct order of these events.
decomposers break down algae and increase
in number
an algal bloom occurs.
