The diagram shows a food web. a food web diagram showing the letter a with an arrow pointing away from it to a beetle. there is an arrow from the beetle pointing to a racoon. there is also an arrow pointing to the racoon from the letter b and an arrow pointing to the racoon from corn. there an arrow pointing from blackberries to the letter b. if a certain organism is a producer, what best explains its position in the food web? b, because organism b utilizes radiant energy from the sun a, because organism a has the same role as the corn b, because organism b has the same role as the racoon a, because organism a utilizes energy from the beetle question 8(multiple choice worth 3 points) (01.04 lc) which of these is true about the total amount of energy in a closed system? decreases destroyed and created increases remains the same question 9(multiple choice worth 3 points) (02.03 mc) how is earth's surface most likely to change as water freezes and expands on a mountain side over time? erosion will cause the ice to crack the rock. physical weathering will cause the ice to crack the rock. chemical weathering will cause the water to dissolve the rock. deposition will cause the water to break the rock into sediment. question 10(multiple choice worth 3 points) (02.03 lc) which of the following could be a characteristic of the fossil that is least related to humans? erect body posture walking on two feet large brain size tree-dwelling question 11(multiple choice worth 3 points) (01.05 mc) four gases are described below: gas a: 3 liters at 42 °c gas b: 9 liters at 12 °c gas c: 9 liters at 42 °c gas d: 9 liters at 12 °c which gases have the same average molecular kinetic energy? gas a and gas b gas a and gas c gas b and gas c gas b and gas d question 12(multiple choice worth 3 points) (01.01 mc) read the given list of organisms. deer, sheep, wolf, cattle, insects what best describes the role of these five organisms in a food web? carnivores, as they all eat meat herbivores, as they all feed on plants consumers, as they all make their own food consumers, as they all obtain food from plants or animals question 13(multiple choice worth 3 points) (02.03 lc) the diagram below shows an undisturbed rock. a rock sample is shown with four layers marked a, b, c, d from top to bottom. which layer is likely to have the remains of an organism least similar to the organism’s present-day form? layer a layer b layer c layer d question 14(multiple choice worth 3 points) (02.02 mc)
