Nutrient Cycling  B.  Resource pulses are occasional events of ephemeral resource superabundance that occur in many ecosystems. Herbivores, like the 17-year periodical cicadas, can have enormous impacts on the growth and reproduction in forest plants. In their immature forms they feed primarily on roots belowground biomass. What types of statistical analysis would you use to the difference in % Leaf N (Figure 7)? (2pts)

The vast majority of a tree’s mass is made of carbon-containing molecules (organic carbon). Where does this carbon come from?

There are 80 swamp sparrows in a 20-hectare section of Mount Meadow. The average population density of sparrows at this site is _______ per hectare.

A fundamental niche

A large plant that grows in a warm, swampy environment and faces substantial herbivory most likely

Consider a population of birds that land on an island. Their numbers rise exponentially until they reach a population of 1,000 birds, after which they crash to 700 due to resource limitations. Over time, the population rises and falls until it stabilizes around a population of 850. What does this population size likely represent in terms of population growth?
