The other variable needs to known for calculating the net ecosystem production (NEP) if the NPP is known. Concept introduction: Net ecosystem production (NEP) is the gross production remain after the loss of total respiration of all the organisms in the system, on the other hand the NPP can be expressed as the amount of novel biomass added by producers in that time.

Analyze the following experiment and answer the questions that follow. Suppose that the growth behavior of a native catfish is to be characterized. To understand the growth behavior implies the possibility of growing the fish in an aquaculture. It is possible to manage the growth of fish in a controlled condition. Accomplish the following. 1. Identify the following: a. Process? b. Input? c. Controllable factors? d. Uncontrollable factors? e. Output? Response variable? 2. Draw the IPO diagram. 3. Make a simple experimental design using the 5-step process, except step 4.

In a study on the ecological impact of malarial infection in the lizard Scelopons occidentalis, researchers caught 15 lizards with the malarial parasite Plasmodium and 15 without. Researchers measured the distance (meters) each lizard could run in two minutes (as a measure of stamina). The following is the code and R output from the "t.test" function. t.test (x=infected, y=uninfected) Welch Two Sample t-test data: infected and uninfected t = -1.9658, df = 27.239, p-value = 0.05959 alternative hypothesis: true difference in means is not equal to 0 95 percent confidence interval: -10.9523489 0.2323489 sample estimates: mean of x mean of y 26.87333 32.23333 The confidence interval includes the value of 0, therefore we conclude that: a. The difference between the treatment and the placebo is positive b. There is no difference between the treatment and the placebo OC. The difference between the treatment and the placebo is negative Od. There is a difference between the treatment and the…
