Which of the following is a limiting factor for productivity in deep lake ecosystem ??
1:nitrogen
2:phosphorus
3:carbon
4:sunlight
Dear student,
In case of a deep lake ecosystem, sunlight is a limiting factor for productivity. Because as the depth of the lake is very high, rate of dispersion of net incoming sunlight over the lake gradually increases with increase in depth. Hence, net sunlight received by primary producers in the ecosystem is very less. Hence, sunlight is a limiting factor for productivity in this ecosystem.
Hence, the correct answer is (4) sunlight.
