Which statement about the classic competition experiments involving two
Paramecium species is FALSE?
The experiment involved interspecific competition.
The experiment involved exploitation competition.
Each species, when grown alone, exhibited logistic growth.
When grown together, the species exhibited logistic growth, but each reached a
lower carrying capacity than when it was grown alone.
Use the data in the Table below to answer the following 4 questions.
1. Create a graph (label this as Figure 1) of species richness and species diversity over the
study years. Upload your graph in the next question.
2. a) When was species richness lowest, and when was it highest? b)When was species
diversity lowest, and when was it highest?
3. What is the effect of invasive species H on community structure in year 3 compared to
year 8?
4. What is the overall impact of invasive species H on the species richness and species
diversity of this community?

By law, one of the habitats must be left intact to satisfy the zoning laws. The developer works with an environmental engineer to choose which of the habitats should be saved. The environmental engineer suggests that Site C should be saved. Which of the following choices best justifies this decision?Responses A) Site C has greater species richness and species evenness than either Site A or Site B. This will promote the maximum sustainability for future generations of animals. B) Site C is tied with Site A for greatest species richness, but unlike Site A, it has representative species from all 3 of the sites within it. C) Site C not only contains the greatest number of species, it also has the greatest genetic diversity within each species.

The students hypothesized that there would be more insect biodiversity in the leaflitter at the nature preserve than at the managed site. The leaf litter from each site was placed into a funnel with alight shone on the top to drive any insects out of the litter.

The fire is contained and burns out and the chemical spill is cleaned up.

Over the next 5 years the area was monitored. The community's diversity, abundance, and richness all increased slightly during the first year however after the first year only the abundance went up during the following 4 years with no changes in any other area.
