Describe what a pyramid of numbers would like if an ecologist models the relationship between bird parasites, blue jays, and oak trees in a hectare. Does this match the energy flow pyramid?

Pick THREE types of ecosystems. Summarize major threats to each of their biodiversity. Summarize how best to bring them back to a climax community.

A community that does not undergo further succession is an apex community. True or false?

Diagram the “Latin” city model of urban growth. Name all of the different sections and explain where the Brazilian flavelas fit in the model.

QUESTION 5 Examine the data below. Species R*nutrient1 R* nutrient 2 R* nutrient 3 One 5.0 7.0 7.0 Two 10.0 3.5 5.0 Three 15.0 10.0 15.0 A community that contains species 1, species 2, and species 3 currently has only two resources available: nutrient 2 and nutrient 3. What is the expected result? O A. Species 1 would win O B. Species 2 would win. O C. Species 3 would win. O D. There would be competitive exclusion. O E. There would be coexistence.

How do you know when an area reaches its climax community? What would you want to see in that area for it to be a climax community?

According to the resource-ratio hypothesis (a.k.a. R-star), what factor(s) will determine the maximum number of competing species that could possibly coexist in a community? (Note: either one or more-than-one answer could be correct) .what does the number of limiting resources in a community tell us? The number of limiting resources in the community The net primary productivity of the community (NPP). The number of trophic levels that are present in the community. | The intrinsic rate of increase (r) of each species in the community. The colonization rate of each species that can access the habitat.

All of the following may be important keystone species due to their roles as pollinators EXCEPT: Question 14 options: - birds - wasps - monkeys - flies - bees   Thank you!

The Jena experiment tested the effects of plant species richness on the ecosystem function of various grassland areas over a 15-year timespan. Ecosystem function was determined by measuring the biomass, soil characteristics, types, and numbers of producers and consumers in the area, and tested to determine the strength of the biodiversity effect on the ecosystem. The graphs show the ecosystem function at the onset of the experiment (dotted line) versus the ecosystem function at the end of the 15-year experiment (solid line) in four different test sites (A, B, C, and D).

You are studying primary productivity and biodiversity patterns of an ecosystem. The ecosystem is represented by the climatograph below. The Gross Primary Productivity (GPP) is measured to be 5000 grams of carbon per square meter per year, and the Total Respiration (RT) is measured to be 300 grams of carbon per square meter per year.  - What kind of biome is this? - Calculate the Net Ecosystem Production (NEP) for this ecosystem - What does the calculated NEP value indicate about the carbon balance and overall productivity of the ecosystem? (one sentence) - Based on both the climatograph and the NEP, what can you say about the biodiversity of plants versus consumers? Choice 1 of 4:plant biodiversity is greater than consumer biodiversity Choice 2 of 4:consumer biodiversity is greater than plant biodiversity Choice 3 of 4:consumer biodiversity is the same as plant biodiversity Choice 4 of 4:lower plant biodiversity compared to consumer biodiversity
