Answer #1

According to the 10% rule of ecology, approximately 10% of the energy recieved by an organism is passed on to the higher trophic level. The rest 90% is used by the organism for its own growth and reproducton.

Let the total amount of solar energy converted to chemical energy be .

The energy used for growth and reproduction

Therefore, the total amount of solar energy converted to chemical energy and cellular respiration for this ecosystem is  .

Plant growth provides food for herbivores that in turn can impact the productivity of the ecosystems that they graze. Herbivores remove green leaves and therefore lower potential whole-ecosystem photosynthesis by reducing the leaf area index. However herbivores may also reduce the amount of shading in the lower plant canopy and fertilize soils with their feces and urine, increasing the amount of light and nutrients for the remaining uneaten plants. Removal of leaves by herbivores may also warm up soils, leading...

In this exercise we will consider two coal-fired power plants and a solar thermal plant, in order to compare their power densities, i.e., their power output vs. the amount of land they occupy. This method of comparison of diverse forms of renewable and non-renewable energy systems was pioneered by Vaclav Smil of the University of Manitoba in Canada. The first coal plant is highly efficient and is optimally located, next to a mine that supplies high-quality coal from a thick...
