35. Base your answer(s) to the following question(s) on the passage below and on your knowledge of
biology
Mayflies
Mayflies belong to a group of insects
known as Ephemeroptera, which means
"shortlived wings." They have been given this
name because the adult, the only stage that
has wings, lives for only a few days.
The aquatic juvenile form of most mayfly
species lives for several years under rocks in
streams that have high levels of dissolved
oxygen. The juveniles feed on microscopic
photosynthetic organisms. Juveniles supply
food for trout and other stream fish.
Millions of adult mayflies emerge from
stream water in early summer. The adults
have wings for flight, but lack functional
mouth parts. Their energy supply comes
from food stored in their bodies. Birds and
bats eat adult mayflies. Adult mayflies mate,
lay eggs, and die within a few days.
