Imagine that you are studying the food preferences of a lizard species across its range. you have hypothesized that because these populations are fairly separate from one another, the lizards have evolved different food preferences. you discover that in the desert, the lizard seems to prefer various types of flies, whereas at higher, wetter altitudes, it prefers one type of beetle. does this observation support your hypothesis?
1. no first i need to determine whether the offspring of these lizards, raised in the laboratory under the same conditions, will reflect the parental food preferences.
2. not only do the lizards prefer different foods, but there is also evidence that the foods they prefer are not necessarily the most abundant,
3. the lizards obviously prefer different foods.
4. this cannot be determined without first sequencing and comparing the lizards dna. first,
5. i must determine if both groups can be trained to eat the same type of food.

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.
