Plants absorb 340000 kcal/m2 /yr sunlight incident on a community in the region. The absorbed light results in a net plant production of 8833 kcal/m2/yr and evapotranspiration of 11977 kcal/m2 /yr. The herbivores consume 3368 kcal/m2 /yr of plant mass and additional intake of 536 kcal/m2/yr from other sources respiring 1760 kcal/m2 /yr of it. 1478 kcal/m2 /yr die of natural causes with the remaining eaten up by the carnivores, provide a net production of 37 kcal/m2 /yr for this higher tropic level with respiration of the former level amounting to 216 kcal/m2/yr. Estimate the trophic efficiencies for the producers, primary and secondary consumers of this food chain.

The accompanying photo shows a pipevine swallowtail caterpillarclimbing up a twig. (a) As the caterpillar climbs, itspotential energy is increasing. What source of energy hasbeen used to effect this change in potential energy? (b) If thecaterpillar is the system, can you predict the sign of q as thecaterpillar climbs? (c) Does the caterpillar do work in climbingthe twig? Explain. (d) Does the amount of work done inclimbing a 12-inch section of the twig depend on the speedof the caterpillar’s climb? (e) Does the change in potential energydepend on the caterpillar’s speed of climb? [Section 5.1]
As scientists research and develop biofuels, they are faced with many tradeoffs. A plant's usefulness for biofuels depends on how much energy can be collected from the plant matter. In addition, growing plants on a large scale requires energy—such as the gasoline and power needed to run tractors and other harvesting equipment or the energy needed to create and distribute fertilizers and pesticides. An efficient biofuel would maximize the ratio of energy output to energy input. The following graph illustrates the results of a 10-year study analyzing three different crops used in biofuel production. The data show how much energy was required to grow each crop on 1 hectare of land (energy input) and how much energy was recovered from the total crop on each hectare of land (energy output). A hectare is a measurement of an area of land and is roughly the same as 2.5 acres. What was the estimated energy input of the grass? A. 2 kcal × 106 B. 4 kcal × 106 C. 8 kcal…

The hormone abscisic acid provides advantages to plants in stress conditions by Select one: inhibiting the growth of nearby plants and so reducing competition attracting beneficial predatory insects increasing tolerance to environmental stress
In a Kansas wheat field, the insolation energy is 5,750,000 calories/m2/day. The gross productivity of the wheat is 0.038 grams/cm2/day, and the respiration loss is 22 percent. One gram of wheat is equivalent to 850 calories. Calculate the net primary productivity of the wheat. Find the efficiency of photosynthesis by the wheat.
In an experiment you grow three different experimental plant plots: a control (no herbivores or nutrients), plants with herbivores, and plants with added nutrients (herbivores still present). Given these results, describe what accurate conclusions can be drawn given the statistical differences represented.
