and H2O. The equation describing the process of photosynthesis is: 6CO2 + 12H2O + light energy --> C6H12O6 + 6O2+ 6H2O C6H12O6 is glucose. Water appears on both sides of the equation because 12 molecules of water are consumed‚ and 6 molecules are newly formed during photosynthesis. We can simplify the equation by showing only the net consumption of water: 6CO2 + 6H2O + light energy --> C6H12O6 + 6O2 The overall chemical change during photosynthesis is the

Carnivorous insects‚ such as the praying mantis‚ control the ‘pest’ insect population. 2. What percentage of the species on this planet consists of insects? Animals? Plants? 53% are insects; 20% are other animals; 18% are plants. 3. Give three examples of how we benefit from microbes. Soil bacteria
