Question

what are the three main cycles of life? label and describe each stage of the water - cycle pictured below. biomes matching. on the lines provided, write the letter of the biome that best matches the description of the climate and species of organisms that live in it. 1. hot and wet year - round, home to more species than all other land biomes combined 2. warm year - round, wet and dry seasons, tall deciduous trees, tigers, termites 3. warm temperatures, frequent fires, tall perennial grasses, herbivores such as antelopes and zebras 4. variable temperatures, low precipitation, cacti and other succulents 5. warm to hot summers, cold winters, fertile soil, perennial grasses, prairie dogs 6. hot, dry summers, nutrient - poor soil, woody evergreen shrubs, chaparral, coyotes 7. cold to moderate winters, warm summers, year - round precipitation, deciduous trees, raccoons, skunks 8. long cold winters, short mild summers, needleleaf conifers, moose, lynx 9. cold, dark, long winters, permanent mosses, lichens, algae, caribou, musk ox list two types of aquatic ecosystems and give their percentage of existence on earth? (know samples of each type of aquatic ecosystem)

Explanation:

1. The three main cycles of life are the water - cycle, carbon - cycle, and nitrogen - cycle.
2. For the water - cycle stages in the picture (not visible here but generally): Evaporation is when water turns from liquid to gas due to heat. Condensation is when water vapor cools and forms clouds. Precipitation is when water falls from clouds as rain, snow, etc. Runoff is when water flows over land back to bodies of water.
3. For the biomes matching:

• Hot and wet year - round, home to more species than all other land biomes combined is the tropical rain forest (c).
• Warm year - round, wet and dry seasons, tall deciduous trees, tigers, termites is the tropical dry forest (g).
• Warm temperatures, frequent fires, tall perennial grasses, herbivores such as antelopes and zebras is the tropical savanna (e).
• Variable temperatures, low precipitation, cacti and other succulents is the desert (b).
• Warm to hot summers, cold winters, fertile soil, perennial grasses, prairie dogs is the temperate grassland (f).
• Hot, dry summers, nutrient - poor soil, woody evergreen shrubs, chaparral, coyotes is the temperate woodland and shrubland (d).
• Cold to moderate winters, warm summers, year - round precipitation, deciduous trees, raccoons, skunks is the temperate forest (a).
• Long cold winters, short mild summers, needleleaf conifers, mosses, lynx is the taiga (h).
• Cold, dark, long winters, permafrost, mosses, lichens, arctic caribou, musk ox is the tundra (i).

1. Two types of aquatic ecosystems are freshwater (about 3% of Earth's water) and marine (about 97% of Earth's water). Freshwater examples include lakes and rivers. Marine examples include oceans and seas.

Answer:

1. The three main cycles of life are the water - cycle, carbon - cycle, and nitrogen - cycle.
2. General water - cycle stages: Evaporation, Condensation, Precipitation, Runoff.
3. Biomes matching:

• 1. c. tropical rain forest
• 2. g. tropical dry forest
• 3. e. tropical savanna
• 4. b. desert
• 5. f. temperate grassland
• 6. d. temperate woodland and shrubland
• 7. a. temperate forest
• 8. h. taiga
• 9. i. tundra

1. Aquatic ecosystems: Freshwater (3%, e.g., lakes, rivers), Marine (97%, e.g., oceans, seas)
