- The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services published a report in 2019 that described several negative effects that humans have had on biodiversity and ecosystem services. They highlighted and ranked five drivers of these negative effects. Which of the following has had the greatest overall impact on biodiversity and ecosystem services? A. Pollution B. Direct exploitation of organisms C. Invasive species D. Climate change E. Changes in land use and sea usearrow_forwardCarrying capacity is defined as a species’ average population size in an environment. Which of the following resulted to exceeding carrying capacity in a particular environment? a. increasing birthrates, decreasing deathrates, increasing immigration and no emigration takes place b. increasing birthrates, decreasing deathrates, decreasing immigration and no emigration takes place c. increasing birthrates, decreasing deathrates, decreasing immigration and increasing emigration d. decreasing birthrates, increasing deathrates, increasing immigration and increasing emigrationarrow_forwardThe relative abundance of any one species within a community of many species is known as a. species evenness. b. species richness. c. specialization. d. population.arrow_forward
- At any point in time, a number of environmental objectives must be met with a limited amount of economic resources. This means that once an environmental problem is identified, they have to be prioritized. In general, this is done using scientific valuation of the relative risk to human health and the ecology of a given environmental hazard - a procedure known as: A. Biodiversity B. Public Goods C. Risk Assessment D. Profit maximizationarrow_forwardDetermine 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_forwardHabitat fragmentation results from human activities that change large blocks of landscape, leading to many negative effects on species and ecosystems. Which of the following is not one of the possible consequences of fragmentation? A. reduction of available habitat O B. increasing degradation of habitat patches C. increasing wind speeds and temperatures at patch edges D. spatial isolation of patches E. increase in top predators present in patchesarrow_forward
