Organisms employ a variety of evolutionary adaptations to them maintain the chemical composition of body fluids. which of the following is not an example of how a given organism maintains such a balance?
(a) some marine invertebrates are osmoconformers; their body fluids are isosmotic with the surrounding environment.
(b)many marine vertebrates offset osmosis by drinking large amounts of water and releasing salt through their gills.
(c) freshwater fish counteract osmosis by drinking large amounts of water and limiting their urination and feeding.
(d)terrestrial organisms reduce water loss with adaptations such as skin, waxy exoskeletons, and closable stomata.

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.
