Springfield has very hot summers and cold winters, while San Francisco has about the same temperatures all year. What is the most likely reason the two cities have such different climates? A. the amount of sunlight on each city B. the distance of each city from an ocean C. the elevation above sea level of each city D. the distance of each city from the equator B Why is pollination important in the reproduction of seed plants? A. Bees and other animals like to eat pollen. B. Pollen must be moved from the stamen to the pistil for fertilization. C. Pollen is needed to produce nectar. D. Pollen has to germinate before plants can reproduce. B D Most plants make food in their leaves using the process of photosynthesis. What role do the stems and roots of most plants play in this process? A. Stems store extra sugar, but roots do not have a role in photosynthesis. B. Stems hold the plant upright, and roots store extra sugar. C. Roots have no role, but stems move sugar to other plant parts. D. Stems carry sugar to other plant parts, and both stems and roots may store extra sugar. An organism that usually eats meat is called a carnivore. A wolf is an example of a carnivore.

Why did the toads disappear? A. The toads were destroyed by the construction equipment. B. The toads died because toads cannot breathe out of water. C. The toads were frightened and went into the woods. D. The toads got their food from the wetland ecosystem. What would happen if there was a drought and the grass did not get enough water? The grass would die, which would cause the number of mice, rabbits, and foxes to go down. Some plants have structures or features that protect them from harm. If a plant has bittertasting leaves, what would this most likely protect the plant against? A. B. C. D.

A. fox, tree, grass B. sun, stream, cloud C. cloud, grass, rock D. stream, cloud, fox Great egrets live in marshes, ponds, and other shallow water areas and eat creatures such as fish. List two of the egret’s body parts that make it a good hunter in shallow water and explain how each body part helps the egret hunt. One body part that helps the egret hunt is its long legs that make it easy to stand in shallow water. Another body part that helps the egret hunt is its big beak which makes it easier to catch fish. SUMMER WINTER Identify two different characteristics of the arctic bird that change from summer to winter and describe how the characteristics help the bird survive in its environment. The bird’s feathers provide a lot of insulation. During the winter, they fluff their feathers to trap air between their feathers and bodies Birds also change behaviors in the cold. Besides eating more, they huddle together for warmth.
