Mark-Release-Recapture

Estimated Population Size=

(Total no. of individuals in first sample x total no. of individuals in the second sample) ÷ (No. of marked individuals recaptured)

1 of 12

Population Growth

Population Growth=

(Births+Immigration)-(Deaths+Emigration)

Percentage Population Growth rate in given period=

(Population change during the period ÷ Population at the start of the period) x 100

2 of 12

Birth Rate and Death Rate

Birth Rate=

(number of births per year ÷ total population in the same year) x 100

Death Rate=

(number of deaths per year ÷ total population in the same year) x 100

ATP + (H2O) --> ADP + Pi + E

 adenosine triphosphate + water --> adenosine diphosphate + inorganic phosphate + energy

Photosynthesis

6CO2 +6H2O à C6H12O6 + 6O2

5 of 12

Photolysis

2H2O --> 4H+ + 4e- + O2

Link Reaction

Pyruvate + NAD + CoA --> acetyl CoA +reduced NAD + CO2

7 of 12

Production of ethanol in plants and some microorga

pyruvate + reduced NAD --> ethanol + carbon dioxide + NAD
