An ecosystem is made up of both living and nonliving things. Biotic factors are the living and once-living parts of an ecosystem, including all of the plants and animals. Biotic factors include dead organisms, dead parts of organisms, such as leaves, and the organisms' waste products. TIle biotic parts of an ecosystem interact with each other in various ways. They also interact with the abiotic (ay bie AlIT ik) factors, tile noniiving parts of the ecosystem. Abiotic factors include air, water, rocks, sand, light, and temperature.

8 Name Class_~~~~~ Date~~~~~ Name~~~~~~~~~~~_ Class_~~~~_ Date_~~~~_ IActive Readi ng continued Section: Energy Flow in Ecosystems Read the passage below and answer the questions that follow. Energy from the sun enters an ecosystem when a plant uses sunlight to make sugar molecules by a process called photosyntmsis. During photosynthesis, plants, algae, and some bacteria captnre solar energy. Solar energy drives a series of chemical reactions that require carbon dioxide and water. The result of photosynthesis is the production of sugar molecules known as ca'i'ijohydmtes. Carbohydrates are energy-rich molecules which organisms use to carry out daily activities. As organisms consume food and use energy from carbohydrates, the energy travels from one organism to another. Plants produce carbohydrates in their leaves. When an animal eats a plant, some energy is transferred from the plant to the animal. Organisms use this energy to move, grow, and reproduce. IDENTIFYINC MAIN IDEAS One reading skill is the ability to identify the main idea of a passage.

9 Review 1. A Belgian priest, Georges Lamaitre, was the first to develop a "big bang" theory. In 1927, after studying red shifts of galaxies, he proposed that the universe began with an immense infusion of pure energy into space. Later, Edwin Hubble discovered that the speed of a galaxy moving away from Earth was proportional to its distance. This relation was predicted by Lamaitres theory. Then, in 1964, Arno Penzias and Robert Wilson discovered the cosmic background radiation, which was also predicted by Lamaitre's theory. Which of the following best describes the work of these scientists and the development of the Big Bang Theory? A. Scientific theories are the cumulative result of evidence from many scientists. B. Scientific theories are rarely confirmed so scientists try to provide more evidence. C. Georges Lemaitre should be given credit as the one who developed the Big Bang theory. D. Because of the work of these scientists, the Big Bang should now be a fact instead of a theory. 2. Which of the following planets has a very hot atmosphere and is about the same size as our earth? A. Jupiter B. Mars C. Pluto D. Venus 5. Which answer below best describes the future of models of the life cycles of stars? A. Models will probably stay the same because scientists do not enjoy creating new models. B. Models will probably stay the same because scientists have learned all there is to know about the life cycle of stars. C. Models will probably change because scientists like to make changes. D. Models will probably change because new technology will provide better information about the life cycle of stars. 6. What kind of evidence do scientists use to locate boundaries of plates and interpret what type of boundary is present? A. matching fossil records B. similar rock layers C. distribution of earthquakes and volcanoes D. the way the continental coastlines fit together like a puzzle 7. Earth's crust and rigid upper mantle are broken into enormous slabs called tectonic plates that interact at plate boundaries. The three types of plate boundaries are transform, divergent, and convergent. Describe the plate movements at two of these boundaries. Give one example of a formation created at each of the boundaries that you described above. 3. Why would a red giant star be brighter than a white dwarf? A. the giant is hotter B. the giant has more surface area C. the giant is closer to the earth D. the dwarf is cooler E. the dwarf is surrounded by gas 4. What causes the earth's seasons? A. the distance to the sun B. the tilt of the earth's axis C. the elliptical orbit of the earth D. the sun is brighter in the summer E. the closeness of the moon to the earth Cf
