ANSWER KEY “The Wolf, the Moose, and the Fir Tree: A Case Study of Trophic Interactions” by Gary M. Fortier Department of Small Animal Science Delaware Valley College Part I – Introduction Experimental manipulations can be quite difficult in systems containing large vertebrates. Consequently, long-term observations and correlational analysis are often used to assess interactions between different trophic levels. The limitations of this approach are well known; strong correlations...

abiotic components - Nonliving chemical and physical factors in the environment (temp, light, nutrients, water) aerobis - needs oxygen to take place Alcoholic Fermentation - plants, anaerobic, Produces ethyl alcohol and a little bit of ATP Altruistic - ___ behavior -individuals put themselves at risk for the benefit of their species -Enhances another individuals reproductive success at the altruist's expense -Makes sense for the survival of kin or the overall group anabolism - Construct...

Which term best defines this organization: All the organisms/ species living in a particular area and the physical components with which the organism interact... - Ecosystem I design an experiment to test whether or not fertilizer has an effect on the growth of dandelions. My hypothesis is that dandelions in soil to which fertilizer is added, will produce more biomass. What is my independent variable in this experiment? - Presence or absence of fertilizer What is an example of Aposematism?...

Eukaryotic cells evolved when an ancestral host cell, probably a ____________ formed a mutualistic, endosymbiotic relationship with ______________ - Answer-Archaean; an alphaprotobacteria Snowball Earth Hypothesis suggests the hardened, spiny exoskeleton evolved as a result of: - AnswerRelease of calcium after global glaciations You find a colony of single celled organisms that are living (thriving and reproducing) in an extreme environment, such as an alkaline or reducing environment. Which...

species correct answers a group of organisms sharing common characteristics that interbreed and produce fertile offspring population correct answers a group of organisms of the same species living in the same area at the same time, and which are capable of interbreeding habitat correct answers the environment in which a species normally lives abiotic factors correct answers non-living, physical factors that influence the organisms and ecosystem, e.g. temperature, sunlight, pH, salinity,...

Which describes meiosis but NOT mitosis? * 0/1 crossing over occurs---only in miosis chromosomes move to opposite poles cell membranes duplicate sister chromatids separate—miosis1 and 2 cell membranes split not duplicate cell membranes duplicate A scientist is studying the oxpecker bird. The birds she studies eat insects from the back of rhinocerous. The scientist studies how this helps the birds and the rhinocerous. She is studying an example of: * 0/1 competition herbivory ...

Amensalism -/0 interactions - : one species is harmed while the other is unaffected Tend to be more accidental than other relationships Example: a herd of elephants that crushes plants and insects while moving through a forest . Commensalism +/0 interaction: - one species benefits while the other is unaffected Brown-headed cowbirds follow grazing cattle and bison, foraging on insects flushed from the vegetation. Cattle convert plants into dung, which dung beetles can use. Dung beetles dispe...
