Ecosystem investigation

Group 2

Abiotic factors

Littoral ZoneOur ecosystem included a mountain creek and an artificial lake. The width of the lake littoral zone was up to 5 meters at some points.

Turbidity

Our turbitidy estimate is 79cm. Water depth at the estimation point is 320cm

We tried to estimate the suspended solids of the lake water

Our estimation is that the lake water contains average residue.

Suspended soils

WATER PH We measured water pH 4 times and we found the following values: 8.37, 8.45, 7.45, 8.33.

Water temperature

We measured water temperature at the water surface 3 times

15o C, 14.4 o C, 14.3 o C
