100 Name 3 things plants need in order to live. Answer: light, water, carbon dioxide
200 Some plants have thick and waxy layers on top of their leaves. This reduces water loss from evaporation. Where would a plant without waxy leaves grow successfully. Answer: Where there is plenty of water.
200 What are producers and why do consumers need them in order to live? Answer: Plants are producers because they produce their own food through photosynthesis. Humans and other consumers must eat producers or animals that ate producers in order to obtain the energy needed to survive.
400 All trees need sunlight, water (H 2 O), and carbon dioxide (CO 2 ). Some trees are taller than others and may have a better chance of surviving than shorter trees. A.In a heavily forested area, what source of energy would a taller tree have more of than a shorter tree? B.Why would that source of energy give the taller tree a better chance of survival in a heavily forested area than a shorter tree. Answer: A. Taller trees in heavily forested areas can receive more sunlight because nothing blocks the sunlight. B. With more sunlight available, a taller tree can make enough food for itself through photosynthesis. The taller tree may block the sunlight so that shorter trees may not receive enough light to make the needed food.
500 Herbivores, carnivores, and omnivores are all consumers. A. Explain the differences between an herbivore, a carnivore, and an omnivore. B. How do all of these depend on plants to live? Answer: A.

300 The timber wolf now inhabits portions of Yellowstone National Park in Wyoming. The timber wolf is a natural predator of elk, deer, and smaller animals such as rabbits. The mountain lion feeds on similar animals. How would the introduction of the mountain lion into Yellowstone National Park most likely affect the population and food source of the timber wolves? Answer: The mountain lion and the timber wolf would compete for the same food sources. This would decrease the population of the timber wolf. There would also be decreases in the food sources that both the mountain lion and the timber wolf eat.

Answer: Answers will vary- should show that student knows that living things compete in a climatic region with other living things and that structural adaptations make them fit for an environment. 500 Many animals live on the African plain and compete for the limited food supply. Each type of animal, including the lion, the zebra, the antelope, and the giraffe, has become adapted to a different niche within this environment. Select one of these animals and describe a specialized trait. Explain how this trait helps it to survive.

500 Ashley’s science group is doing a report on the sun’s energy and the Earth. Ashley is asked to explain to the class why it is cold at the North and South Pole and hot at the equator. How could she explain this using a flashlight and a globe? Answer: She could explain by shining the flashlight at a globe near the equator. The flashlight will be the sun’s rays. Not much light will reach the poles so not much heat will reach the poles either. Therefore it is colder at the poles and hotter at the equator.
