Regarding biological productivity, what do you think is the best explanation for the trend in changing biomass shown in the figure below?

a.) this is best explained by an increase in the number of predators as you move away from the coast. the increase in predators decreases the number of organisms (i. e., biomass) at lower trophic levels.
b.) this is a best explained by a reduction in oxygen as one moves away from the coast. the reduction in oxygen limits aerobic cellular respiration and leads to a decrease in biomass as one moves away from the coast.
c.) this is best explained by a reduction in the availability of food as one moves away from the coast. input of nutrients (from runoff and less commonly upwelling) fuels primary production, thus allowing a greater number of producers and energy availability for higher trophic levels.
d.) this is best explained by the great pressure at depth as one moves away from the coast. this pressure makes it harder for organisms to survive and thus reduces biomass away from the coast.

With the description of the different cell walls, membranes, and associated proteins set in the students' minds, you now need to introduce them to the idea that the cell wall can also act as a foundation to build things upon. bacterial appendages require a strong foundation that will offer the support needed to move and function in a dynamic world. for example, flagella are long, whiplike protein structures that are used by many gram-positive and gram-negative bacteria for locomotion. in order to function effectively, a flagellum must be firmly anchored to the cell wall. how will you be able to get across the idea that the peptidoglycan cell wall is strong enough to support such a mechanism? with a protein rod that passes through the cell wall and protein rings used to anchor it in the membranes, these basal bodies are the rudimentary biological motors that use atp power to spin the hook and the flagella attached to it. bacterial flagella have a biological motor that spins within the cell wall and is powered by atp. this allows the flagella to spin in a whiplike motion to propel the bacterium.

Me . based on the data in your tables, did the light-colored moths have a higher or lower survival rate after the industrial revolution?
