  3. Large area with similar climate, soil, and plants and animals The Planet of living and nonliving things All the organisms in a particular place + their nonliving environment ECOSYSTEM BIOSPHEREBIOME Matching:

  4. Large area with similar climate, soil, and plants and animals The Planet of living and nonliving things All the organisms in a particular place + their nonliving environment BIOME BIOSPHERE ECOSYSTEM Matching:

  5. What is the difference between photosynthesis and chemosynthesis? (answer below) • PHOTOSYNTHESIS- • organisms capture sunlight to make food • CHEMOSYNTHESIS- • organisms use chemical energy (like sulfur) to make food

  6. How do these relate? • Autotrophs Heterotrophs Consumers Producers • ANSWER: Autotrophs and Producers are plants that make food • Heterotrophs are consumers that eat the producers

  7. Carnivore Herbivore Omnivore Decomposer Detritivore Eat animals Eat plants Eat animals + plants Break down and eat dead organic matter Feed on plant and animal remains called detritus What would each of these eat?

  8. How much energy is… • Usually passed to the next energy level in an energy pyramid? • A. 5% • B. 10% • C. 35% • D. 90% • ANSWER: 10%

  9. What contributes CO2 to the atmosphere? • Detergents • Auto exhausts • Fertilizers • Factories • Ozone • ANSWER: auto exhausts + factories

  16. What chemical form is carbon usually found in rocks? In the atmosphere? • A. CO2 • B. carbonate • C. CO • D. nitrates • ANSWER: in rocks is carbonate • in atmosphere is CO2

  17. What are the three most abundant greenhouse gases? • A. water vapor • B. nitrogen oxide • C. carbon dioxide • D. methane • E. phosphates • ANSWERL A, C, D

  18. What criteria determine a terrestrial biome? • Type of fish • Climate • Type of soil • Plants and animals • Type of people • ANSWER: climate, soil, plants and animals

  19. What is a wetland? • A. lake • B. stream • C. marsh • D. ocean • ANSWER: marsh (water covers the land part of the time)

  20. WHICH BIOME? • Hot and wet year round • Ferns, large woody vines and climbing plants, orchids • Sloths, tapirs, jaguars, monkeys, toucans, butterflies • S. and central Am., SE Asia • ANSWER: Tropical rainforest

  21. WHICH BIOME? • Humus soil • Cold to moderate winters, warm summers, fertile soils • Deciduous trees, some conifers • Deer, black bears, squirrels, raccoons, turkeys, songbirds • ANSWER: Temperate Deciduous Forest
