Chapter 55, Problem 3TYK
Summary Introduction
Introduction:
The International Union for the Conservation of Nature (IUCN) is an international network of non-government organizations (NGOs) and government agencies that monitors the status of the ecosystem and species. It organizes conferences about the ecological challenges and maintains the red list apart from sponsoring scientific research.

biodiversity and ecosystem services?

- Determine if each statement is correct or incorrect: 1. Ecosystems with fewer numbers of species tend to be less stable. 2. Increasing numbers of species lead to more redundancy which is bad for the ecosystem. 3. More species mean more niche separation. 4. Species with a low resistance will also have low resilience. 5. Disturbances to ecosystems can be both naturally occurring and human caused. 6. Stresses to ecosystems are useful for removing weaker species and ensuring the strongest survive. 7. Bringing non-native species into an area to increase biodiversity makes the ecosystem more stable.arrow_forwardCommunities are defined by? A). Species whose ranges overlap B). Species that have the same ranges C). physical features of a defined geographic region D). The area occupied by the species with the largest rangearrow_forwardWhich of the following statements best represents the productivityhypothesis regarding species richness?a. The larger the area, the greater the number of species that will befound there.b. Temperate regions have a lower species richness due to the lack oftime available for migration after the last Ice Age.c. The number of species in a particular community is directly relatedto the amount of available energy.d. As invertebrate productivity increases, species richness will increase.e. Species richness is not related to primary productivity.arrow_forward
- A conservation biologist has been asked to explain why it is important to protect biodiversity. She would list all of the following reasons except for which one? A. Humans are dependent on many species for food, medicines, fiber, and other necessities. B. Biodiversity can be exploited indefinitely for the profit of humans. C. Other species have inherent value and humans have a moral obligation to protect them. D. Biodiverse ecosystems provide ecosystem services that sustain all life on Earth. E. Biodiversity provides emotional and physical health benefits by providing places for humans to visit for wonder, insight, and exercise.arrow_forwardWhich of the subsequent options is not included in the red list criteria for species classified as "critically endangered"? 1. The population is projected to decrease by 25% or more within a span of 3 years or 1 generation. 2. The species possesses a limited range of less than 100km2 in a solitary location, and there is evidence of or anticipated habitat loss, fragmentation, ecological imbalance, or significant commercial pollution. 3. The likelihood of extinction exceeds 50% within a timeframe of 10 years or 3 generations. 4. The overall population size consists of fewer than 200 mature individuals.arrow_forward1)Which of the following are stages in the process of primary succession? Select all that apply. Pioneer species colonize the habitat and help build the soil. Shrubby species take root and overgrow the pioneer species. The initial habitat has no soil and lacks multicellular organisms. A disturbance removes the natural array of species but leaves the soil in place. After the buildup of organic matter and nutrients from generations of pioneer and shrubby species, tall trees establish in the habitat. 2)Which of the following is a species interaction that benefits one species and neither helps nor harms the other? Herbivory Commensalism Competition Mutualism 3)Which of the following is a process whereby two species compete for a limiting resource and one drives the other to local extinction? Character displacement Resource partitioning Competitive exclusion 4)Which of the…arrow_forward
- 1) Which of the following defines the niche of a species? The role of a species in its community as well as the conditions it requires and the interactions it takes part in All populations of all species in some area The type of environment in which a species lives The number of species and their relative abundance within a community 2) Which of the following is an example of a biological factor that can affect community structure? Tropical regions support a high species diversity by receiving the most sunlight energy. The high temperatures of desert regions limit which species can live there. A plant species can live only in regions with a suitable level of rainfall. An insect herbivore inhibits the population growth of a tree species. 3)Which of the following prey defensive adaptations involves two or more prey species coming to resemble one another?

- 1) Compare the biodiversity indices to one another. State a claim about the effect of pollution on the biodiversity of the stream ecosystem. Describe how the pollution levels affect the species richness and biodiversity of the stream. Justify your claim with evidence. Describe the difference in species richness you observed. Explain how human intervention can change biodiversity in positive ways.arrow_forwardSite A Site B Site A7 Species Site B = 5 Species *A*+* + Site C7 Species A Site C A vs B = 8 species B vs C = 6 species A vs C = 10 species A developer owns the property encompassing the three habitats above. 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? 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. 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. Site C not only contains the greatest number of species, it also has the greatest genetic diversity within each species. Site C has more unique species in it than either Site A or…arrow_forward1.
