1 Name period date assigned date due date returned Vocabulary Match the vocabulary word to the correct definition. 1. biotic 2. abiotic 3. biodiversity 4. biome 5. sustainability 6. habitat 7. species 8. community 9. niche 10. ecosystem A a community of organisms and their abiotic, or nonliving environment. B the place in which an organism lives. a group of organisms that are closely related and can mate to produce fertile offspring. D large geographic areas with similar temperatures and rainfall amounts. E made up from all of the organisms in an ecosystem. F organisms living or that had once lived in the environment. G the number and variety of organisms living in an area. H non-living factors in the environment. I particular area in an ecosystem where an organism lives. the ability of an environment to support life over centuries. 1

2 Biomes Match the biome to the right description. 11. freshwater 12. desert 13. marine 14. rainforest 15. tundra 16. grassland 17. taiga 18. deciduous forest A found in the Arctic and high mountains. Ground is permafrost and there is very little precipitation. B also called the boreal forest. Mostly coniferous trees, low temperatures and more rainfall than the tundra. Large areas of mostly grass with few trees. Many herbivores live here. D Very dry biome. an become very hot during the day and cold at night. Organisms are adapted to dry conditions and extreme temperature changes. E Water without salt. limate and organisms depend on where it is located on the Earth. F temperate forest areas in which the trees lose their leaves and go dormant in the fall and winter. Some of the animals hibernate. G Salt water environment. There are different zones based on water depth. The type of organisms can be different in each zone. H Tropical or temperate. Large numbers of trees and heavy precipitation. 2

3 Sustainability examples: 19. Two farmers try to out-produce each other by using different planting techniques. Field 1 grew more until a virus killed all of crop 2. How would this virus effect the two farmers? 20. How are the farmer s fields similar to how biodiversity allows an ecosystem to be stable? 21 Which ecosystem has a better chance of surviving when environmental conditions change? A One with a great deal of genetic diversity. B One with plants and animals but no bacteria. One with animals and bacteria but no plants. D One with little or no genetic diversity. 22 Why do plants that grow in the tundra have shallow root systems? F They have no soil in which to grow. G They cannot grow through the permafrost. H They are frequently soaked by heavy rains. They are trampled each time animals migrate. 3

4 23 Scientists classify climates and biomes based on - A latitude and longitude B latitude and elevation temperature and rainfall 25 Where would you most likely find the greatest variety and numbers of animal life? A on a newly mowed lawn B close to a pond with rocks, water and several types of plants D temperature and altitude in the center of a pond D next to a paved surface 24 omplete this statement. The more diverse an ecosystem is - F the more threatened its populations are G the more similar the species will be H the more stable it is 26 Deforestation, pollution, and over hunting can result in - F increase in biodiversity G decrease in biodiversity H no effect on biodiversity a state of equilibrium the fewer varieties of species are present 4

5 27 Which of the following would be true about an ecosystem with plenty of light and water? A B D The ecosystem will contain a lot of the same type of producer. The ecosystem will have a hard time sustaining any consumers. The ecosystem will contain too many consumers. The ecosystem will contain a lot of and a variety of producers. 28 A good adaptation for living in a grassland would be - F the ability to hibernate G the ability of plants to grow very high to reach the sunlight H thick, insulating fur the ability of plants to grow after prairie fires 29 Which of the following situations contributes to stability in an ecosystem? A increase in biodiversity B decrease in biodiversity extinction of a population from the ecosystem D removal of many populations of organisms 5

6 30 Plants have a hard time living in a desert. Which of the following is the primary limiting factor? F elevation G space H food source moisture 32 Some desert animals are most active at dusk and dawn. This adaptation is MOST helpful for - F G preying on plant species finding new water sources H avoiding high temperatures hiding from hungry animals 31 A canopy, an understory, and an extremely high number of plant and animal species are characteristics of which biome? A temperate rain forest B deciduous forest desert D tropical rain forest 33 The picture shows organisms from one of the major biomes on Earth. Which biome are all of these organisms able to live in? A tropical rainforest B tundra ocean D desert 6

7 34 Abiotic factors that could affect the stability of an ecosystem could include: F hurricanes, packs of wolves, and temperature G blizzards, heat waves, and swarms of grasshoppers H droughts, floods, and heat waves fish, number of decomposers, and algae 36 Which ecosystem has a better chance of surviving when environmental conditions change over a long period of time? F one with a great deal of genetic diversity G one with plants and animals but no bacteria H one with animals and bacteria but no plants one with little or no genetic diversity 35 How is a tundra biome similar to a desert biome? A Both biomes have dry, rocky soils. B Both biomes lack plants or animals. Both biomes are hot during the day and cold at night. D Both biomes are characterized by very little precipitation. 37 Which example represents an abiotic factor in an aquatic ecosystem. A Water lilies float on top of a pond. B A population of bass is living in a lake. The ph of a lake is decreased by acid rain. D Dragonflies feed on small insects near a pond. 7

8 38 Base your answer to the following question on the graph below. If the environment was to change dramatically, or a new plant disease were to break out, which plant type would most likely survive? F wild wheat G domestic wheat H wild corn domestic corn 39 What is one way that a temperate rain forest is different from a temperate deciduous forest? A B D A temperate rain forest has large populations of grasses rather than tall trees. A temperate rain forest is made up of palm trees rather than coniferous trees. A temperate rain forest has a rainy season rather than year round rainfall. A temperate rain forest has trees that that lose their leaves in winter rather than keeping them year-round. 8

9 40 Which of the following is an example of a marine ecosystem? F pond G river H wetland open ocean 41 The diagram below shows interactions between different animals in an ecosystem. What type of ecosystem might be represented by the above diagram? A B D ocean desert wetland arctic tundra 9
