ECOSYSTEM

Q.1) How does the man made ecosystem differ from the natural ecosystem? 

 

Ans1) Man made ecosystem Natural ecosystem Under regular control not under the control of man And monitored by man

 

Q.2) Detritus contribute to the biogeochemical cycles, how? 1

 

Ans2) By the decomposition of detritus, the simple minerals are released into the atmosphere & from there it come back to the earth.

 

Q.3) Can temperature regulate the rate of decomposition how? 1

 

Ans3) High temperature favours decomposition and low temperature inhibits decomposition.

 

Q.4) The detritus food chain and grazing food chain differ. How? 1

.Ans4) Detritus food chain begins from the dead and decaying matter while grazing food chain starts from the green plants(Producers).

Q.5) "The Green Revolution has been achieved due to the use of improved crop varieties and agrochemicals, but it is still not enough to feed the growing population". Suggest a suitable method of agriculture to meet the demand. 1

 

Ans5) Vegetation changes in turn change the food and shelter for various types of animals. As a result the foresaid changes happen.

 

Q.6) A species of Solanum is intolerant to salty soil. How will you make the species tolerant to the given abiotic stress?. 1

 

Ans6) In burnt out forests and flooded lands some soil or sediment is present. There is no need for soil to be formed.
