Since 2010, Wolf Willow with a Borden designation of FbNp-26 has been the site of the excavations, where a ten metre by eleven-metre hole was dug and methodically excavated by archaeology students from the University of Saskatchewan. This…

“The unnamed peaks towering over the glacier were bigger and comelier and infinitely more menacing than they would have been were I in the company of another person. And my Lin 8 emotions were similarly amplified: The highs were higher; the periods of despair were deeper and darker” (138). • “The accumulated clutter of day-to-day existence — the lapses of conscience, the unpaid bills, the bungled opportunities, the dust under the couch, the inescapable prison of your genes— all of it…

This is one way in which energy is transferred between organisms in an ecosystem. The energy is used for a number of life processes. In a food chain only around 10 per cent of the energy is passed on to the next level. The rest of the energy passes out of the food chain in a number of ways: 1. via heat energy 2. is used for life processes (for example movement) 3. uneaten parts that pass to decomposers 4. is excreted and passes to decomposers. As less energy is transferred at each level…
