SEQUENCING INFORMATION
One reading skill is the ability to sequence information, or to logically place items
or events in the order in which they occur.
Sequence the statements below to show the steps to a shortage of fuel wood.
Write "1" on the line in front of the first step. "2" on the line in front of the second
step, and so on.
7. The growing population begins to cut down living trees for fuel.
8. The area in which the population lives may become cleared of
vegetation.
9. The amount of available wood decreases.
10. A low population that was using deadwood starts to grow rapidly.
11. The deadwood does not accumulate fast enough to provide the
population with enough fuel.

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.
