Part 2:
a) If the cells are changing in the fishes' gills, they are proberably not working efficiently enough to keep them alive.
b) If i am a scientist I would first gather data about the number of fish dying and the types of species affected. I would also collect information about the changes in the PH of the lake aswell as the changes in salinity and temperature, aswell as any toxins entering the lake and compare these values with any recorded data from the past. I would also check to see if this type of problem has previously occured by checking records from the fisheries department aswell as surveying any locals.

Excercises pg 251 question 2
Why would these changes kill the fish?
The fish are dying because both there organs and gills are trying to adapt (change), there environment. This is because the water is becoming more and more salty which the fish aren't use to which then results in them dying.
If you were a scientist investigating the fish kill, where would you start and how would you go about the investigation?
Firstly I would start at the lake, testing the salt level of the water which could be effecting the fish.and also the amount of phosphates entering the lake. last of all I would get one of the fish and see what is happening with its organs and gills by dissecting it.

TASK CARD EIGHT
Producer>first consumer>second consumer>third consumer
oh my god i forgot to draw the producer!
by Daniel
task card 12 question 1
in an urban ecosystem the humans control it alot more, we farm our food and have water stored for us but in a natural ecosystem the animals have no control over what happens and have to find food and water for themselves. and they have to protect them selves from other animals.
the picture is of a natural ecosystem in the ocean. it has fis and coral which is the place where fish live and eat.
