These flowers are so long and thin that only hummingbirds can get to the nectar. What would be the advantage of only letting certain creatures get the nectar?

  1. It makes it more likely that the flower will be pollinated.

    Yes! As you can see in the Flowers video, the flower needs a pollinator to carry its pollen to another flower of the same kind. If only hummingbirds can get to the nectar, they are more likely to visit other flowers of the same kind. By doing that, they carry pollen from one flower to another, pollenating them. That makes this a strong advantage for the plant.
  2. It keeps animals from eating the nectar.

    No. The nectar is supposed to be eaten. It serves as a treat to get animals to come to the flower.
  3. It helps the hummingbirds get more food.

    No. While getting more food would be an advantage for the hummingbirds, it would not help the plant.
  4. There is no advantage.

    No. Flowers have specific shapes, colors, and smells for a reason.

SC.7.L.15.3 Explore the scientific theory of evolution by relating how the inability of a species to adapt within a changing environment may contribute to the extinction of that species.

UT.5.V.2.c Describe how a particular physical attribute may provide an advantage for survival in one environment but not in another (e.g., heavy fur in arctic climates keep animals warm whereas in hot desert climates it would cause overheating; flippers on such animals as sea lions and seals provide excellent swimming structures in the water but become clumsy and awkward on land; cacti retain the right amount of water in arid regions but would develop root rot in a more temperate region; fish gills have the ability to absorb oxygen in water but not on land).

UT.6.V.1.b Compare characteristics common in observed organisms (e.g., color, movement, appendages, shape) and infer their function (e.g., green color found in organisms that are producers, appendages help movement).

UT.7.IV.2.a Predict why certain traits (e.g., structure of teeth, body structure, coloration) are more likely to offer an advantage for survival of an organism.

Which part of the food web does this Red Shouldered Hawk fit into?

  1. Producer.

    No. A producer captures energy from sunlight, and stores it as food. To do that, the organism needs to contain chlorophyll. This hawk cannot use the energy of sunlight to produce its own food.
  2. Primary Consumer.

    No. Primary consumers eat producers. This hawk does not eat living plants.
  3. Secondary Consumer

    Yes! Secondary consumers eat other consumers. This hawk eats mice, snakes, and other animals.
  4. Decomposer

    No. Decomposers break down dead and decaying organisms. The hawk may occasionally act as a scavenger, eating a freshly dead animal that it did not kill, but it is not a decomposer.

Incandescent light bulbs use electrical energy to produce light energy, but it is not a direct transformation. Instead, the electrical energy is changed to a different form of energy, and then to light.

Electricity → ? → Light


What form of energy does the "?" represent?

  1. Sound

    No. Electrical energy can be transformed into sound energy, but that would not cause the bulb to light.
  2. Thermal

    Yes. As electrical energy flows through the filament, resistance changes the electrical energy into thermal energy. When the filament gets hot enough, some of the thermal energy is converted into light.
  3. Radiation

    No. The electrical energy is not transformed into radiation.
  4. Friction

    No. The electrical energy is not transformed into friction.

Why are trees an important part of the water cycle?

  1. Trees need water.

    No. While trees do need water, that is not why they are part of the water cycle.
  2. Transpiration

    Yes! In order to get nutrients up to the top of a tree, it has to let water evaporate from its leaves. This process is called transpiration. One tree can put hundreds of gallons of water into the air as water vapor every day.
  3. Trees help prevent erosion.

    No. While trees can help prevent erosion, that is not why they are part of the water cycle.
  4. Condensation

    No. Trees are not a major source of condensation.
