Gippsland Lakes

1)
a. the possible reason the water is becoming increasingly saline is because in 1890 lake victoria was opened at lakes enteranceand is dredeged to keep it open.

b. global warming is the most likely possibility of the temperature increasing.

c. Drought has caused less rainfall and the lake is drying up.

d. clearing of vegetation has allowed room for algal blooms

e. drought and urban ecosystems have drained the rivers of lots of water and all that rermains is lots of salt in a small amout of water.

2)

a. the changes in the cells have killed theier function and the fish have suffocated

b. i would start finding what changed the cells in the fish gills and then finding the source of this chemical and get rid of it and make sure it never happens again by purging it from the river ecosystem

Thanks for reading!
