This chemical energy is used to power new biochemical reactions, which again produce stored chemical energy in the consumers' bodies. Use Slide 6 to discuss the left side of the diagram, showing how carbon cycles from inorganic to organic carbon pools. 1 9. But resources can vary with time, for example, in an annual cycle. The number of individuals of any species present in an ecosystem depends on the resources available to support them. 2.1 Ecosystems Have interactions among Predators, Consumers and. Another important human impact lies in changing the Earth's land covers—for example, in clearing forests or abandoning agricultural areas, or in letting agricultural areas grow back to forests or rangelands. This means that, generally, both the numbers of organisms and their total amount of living tissue must decrease greatly up the food chain. Photosynthesis of carbohydrate requires a series of complex biochemical reactions using water (H2O) and carbon dioxide (CO2 ) as well as light energy. The overall reaction is: –CHOH– + O2 ? 3. 1. Nitrogen as N2 in the atmosphere can't be assimilated directly by plants or animals. Figure 8.11 diagrams the nitrogen cycle. Net photosynthesis is the amount of synthesized carbohydrate remaining after respiration has broken down sufficient carbohydrate to power the plant: Net photosynthesis = Gross photosynthesis ? • What do you notice about changes you can make in the Sim?
