- 4. In a few sentences, relate the amounts of energy needed to heat the cold and hot water with the amounts of time that it took to heat each sample. Do the results make sense? Why?2. Gross primary productivity in an equatorial grassland is 8,000 cal/m'/yr. This particular region has such a high efficiency that the grasses use only 75% of the energy in cellular respiration. Calculate the energy (calories) that is available to secondary consumers from 1 m of grassland over a year's period. 2. 8000 x75% =6000 callm/yr 0 callm²lyr2. Rank metals, ceramics, and polymers in order of expected coefficient ofthermal expansion (from highest to lowest) based on their atomic structure, andexplain why this behavior occurs
