- The burning of fossil fuels releases CO2 into the atmosphereand is detrimental to the Earth’s ecosystems. Explain whythe use of biofuels, which also release CO2, is an improvement over fossil fuels.Which of the following processes increase(s) the amount of atmospheric carbon in the carbon cycle? (a) photosynthesis (b) cellular respiration (c) combustion (d) a and c (e) b and cAn abundance of___________ in Earths early atmosphere would have prevented the spontaneous assembly of organic compounds on early Earth. a. hydrogen b. methane c. oxygen d. nitrogen
- Changes in the Air To assess the impact of human activity on the carbon dioxide level in Earth's atmosphere, it helps to take a long view. One useful data set comes from deep core samples of Antarctic ice. The oldest ice core that has been fully analyzed dates back a bit more than 400,000 years. Air bubbles trapped in the ice provide information about the gas content in Earth's atmosphere at the time the ice formed. Combining ice core data with more recent direct measurements of atmospheric carbon dioxideas in FIGURE 46.20can help scientists put current changes in the atmospheric carbon dioxide into historical perspective. FIGURE 46.20 Changes in atmospheric carbon dioxide levels (in parts per million). Direct measurements began in 1980. Earlier data are based on ice cores. 4. Was the rise in the carbon dioxide level between 1800 and 1975 larger or smaller than the rise between 1980 and 2013?Changes in the Air To assess the impact of human activity on the carbon dioxide level in Earth's atmosphere, it helps to take a long view.

FIGURE 46.20 Changes in atmospheric carbon dioxide levels (in parts per million). Direct measurements began in 1980. Earlier data are based on ice cores. The industrial revolution occurred around 1800. What was the trend in carbon dioxide level in the 800 years prior to this event? What about in the 175 years after it?why was the first mini threshold of life's evolution, photosynthesis, so important? a. it helped plants move onto land b. it transformed our atmosphere from oxygen-rich to carbon dioxide-rich c. it allowed life to spread beyond oceanic vents d. it forced organism to become multicellular to process more complex energy

Whatvform of respiration do think was used by earliest form of life? Explain your answer.
- Which of the following is True about ocean ecosystems?a. Surface waters typically have abundant sunlight but lowlevels of nutrients.b. Because there isn’t enough sunlight for photosynthesis,deep waters typically have no life.c. Surface waters in the open ocean have the highestproductivity.d. Life near hydrothermal vents relies on photosynthesisfor energy.Human use of fossil fuels has what consequences? Group of answer choices a. increase in CO2 concentration in the atmosphere b. return of fossilized carbon to the active carbon cycle c. increase in global temperatures d. all of the other optionsUnderstanding that carbon cycles, what action could we do in order to remove carbon from the atmosphere? Group of answer choices a. Dig up less coal b. Discard less plastic in ocean surface water c. Clean up more leaf litter and animal waste d. Plant more trees
