You are asked to estimate the number of species in a 1-hectare section of panamanian tropical forest. after a week you have identified 142 plant species. however, the panamanian government needs a report the next day, and you know that you have not yet identified all of the plant species. you decide to estimate the total species richness from your collected data. you look through your data and discover that you have collected two individuals for 32 plant species and one individual for 47 plant species. estimate the total number of plant species present in this 1-hectare plot using this formula:

For the strategies below, decide whether they are best described as demand-side solutions or supply-side solutions to meeting human needs for fresh water. remember that a demand-side solution reduces demand for fresh water, whereas a supply-side solution increases the supply of fresh water. (a) damming a river to create a reservoir (b) desalinating seawater (c) a nation invading a neighboring country to access their rivers (d) raising water prices for consumers and businesses (e) providing tax breaks for companies that use less water (f) replacing inefficient irrigation with more-efficient drip irrigation to grow crops (g) requiring low-flow showerheads in all new homes
