Guys, does anyone know the answer?
get when moving upward on an energy pyramid from one level to the next, what happens to the usable energy in an ecosystem? from EN Bilgi.
energy flow and trophic levels
The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat. If a grassland ecosystem has 10,000 kilocalories (kcal) of energy concentrated in vegetation, only about 1,000 kcal will be transferred to primary consumers, and very little (only 10 kcal) will make it to the tertiary level. Energy pyramids such as this help to explain the trophic structure of an ecosystem: the number of consumer trophic levels that can be supported is dependent on the size and energy richness of the producer level.

ENVIRONMENTAL SCIENCE
Coffee is a very economically important crop. In fact, only petroleum is more valuable on the world market. Most coffee is grown in full sun on large tropical plantations where coffee plants are the only species present Given that an average American consumes about 9 pounds of coffee per year. Shade-grown coffee helps protect tropical habitats because the land doesn't have to be cleared to grow the coffee plants. Assume that a pound of shade-grown coffee costs $1.50 more than a pound of traditional coffee, and that the added money goes to conservation efforts. If everyone in your state switched to shade-grown coffee for a year, how much money could be generated for conservation?
