The figure below shows a very simplified interaction of energy flow or a northern hardwood forest where an invasive earthworm has become part of the system. Earthworms are powerful ecological engineers. They alter the physical properties of soil that change soil moisture, nutrient availability and soil structure. The figure below depicts the activity of the invasive earthworm changes the soil structure and soil environment in a way that has a direct negative effect on fungi and microbial decomposers. Using this figure, please select the best answers for the blanks in the following paragraph. Primary Producers IT [Select] Fungi and microbe decomposers [Select] Non-native earthworms Soil insects Based on this figure, if earthworms were removed from this system there would be an [Select] in net primary production leading to a/an Salamanders in the biomass available for decomposition and a/an in the populations of salamanders. When earthworms are present the there is an indirect decrease in plant productively. Decreased plant productivity would cause an/a [Select] on biomass available for earthworms.

what is the appropriate title and problem statement and rationale of "You are a microbial ecology researcher with expertise in agricultural soil. You own a company that carry out consultation and produce biological fertilizers. Currently, you have three different products (Biofertile X, Biofertile Y, Biofertile Z). An organic agriculturist growing crops that needs a healthy fungal to bacteria ratio in the soil to increase productivity seeks to know which of your product will best achieve his goal".
