Most bacterial species have an optimal surface area-to-volume ratio (SA/V) that balances growth, available nutrients, and cellular components. The image shows two bacterial species, one with a spherical shape (A) and another with a rod/cylindrical shape (B). Species A is a spherical shape with nodules. Species B is shaped like a cylinder.

Based on surface area to volume ratios, which of the following statements will be true regarding nutrient diffusion within the bacterial species?

A) It will be the same in species A and species B since both have similar SA/V ratios.
B) It will be slower in species A than in species B since species A has a higher SA/V ratio.
C) It will be faster in species A than in species B since species A has a lower SA/V ratio.
D) It will be faster in species A than in species B since species A has a higher SA/V ratio.

The diagram below represents a marine food web and a process that can harm the human population. each circle represents an organism and the smaller dots inside them represent a toxic substance. what is being represented and how does it harm the population? the diagram represents biological half-life, in which toxins build up in organisms higher up on the food chain, and this can negatively impact humans who consume the organisms and the toxic substance. the diagram represents biomagnification, in which toxins build up in organisms higher up on the food chain, and this can negatively impact humans who consume the organisms and the toxic substance. the diagram represents the process by which different organisms prey upon each other; this can impact the human population by reducing the number of organisms that do not contain the toxin. the diagram represents the way that toxins are metabolized by living organisms, with those at greater trophic levels able to metabolize more efficiently than those at lower levels. this means that those at higher tropic levels are safer for humans to consume compared to the organisms at lower trophic levels.
