The bass and crayfish likely “died off” because the rapid growth of the algae eventually caused the level of dissolved oxygen to decline to a point that these
oxygen-dependent organisms could no longer survive. How would you modify this
investigation of the pond organisms to determine if the algal bloom really was the cause of
the bass and crayfish die-offs?

The lake of the ozarks is a human-made lake, so it collects runoff from coal strip-mining, fertilizers, resort wastewaters, and septic drainages. the average lake temperature is between 10∘c and 21∘c. consider the physical requirements for growth and multiplication that would allow fecal coliforms to “blossom” in the lake of the ozarks. which of the following would accurately describe these organisms? check all that apply. psychrophiles facultative halophiles extremophiles mesophiles hyperthermophiles
