Val works as a paleoclimatologist in Alaska. While studying ice core samples, she identifies an increase in the isotopic ratio of oxygen
10,000 years ago. From this discovery, she knows that Earth's temperature at that time was
✓ Aside from
temperature, Val can also learn about
✓ from the ice cores. Val's data suggests that she's uncovered a glacial
climate for this time period. During a glacial climate, Val knows, there would have been
sea level, compared to what
she witnesses today.

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.
