- Find the flaws within the sentance/s Extinction is the complete disappearance of a species from Earth. A mass extinction is when more than half of all extant species disappear from the fossil record and there have been at least five of them. In order to prevent the extinction current species, some areas of earth are preserved while others are conserved. Conservation seeks to prohibit human activity in an area. Preservation seeks the sustainable use and management of natural resources. An endemic species is only found in one location. A biodiversity hotspot has over 1500 species of endemic insects and 70% of the area has been disturbed. There are 34 biodiversity hotspots on Earth. Many sustainable practices are used in agriculture. Crop rotation is the practice of growing different kinds of crops in the same area in sequenced seasons. Conservation tillage is any method of soil cultivation that completely tills under the soil to prepare for the next crop. Genetically modified crops are…Consider a species that occupies a large, but fixed, number of islands. The distribution of the species across all islands is maintained by a balance between local extinctions and local colonization events. Devise a model for the relationship between the fraction of islands occupied by the species and time. Be clear to outline the assumptions you make and be sure to describe your key predictions. Please provide a model for this relationship and be clear to outline the assumptions you make and be sure to describe your key predictionsDescribe the evidence for the cause of the Cretaceous–Paleogene (K–Pg) mass extinction.
- What would the extinction rate be for a 30 square mile island that is 1000 miles from the mainland and has 150 species on it. Assume the extinction probability for each individual species is 0.8 and the power scaling function is 0.25. Round your answer to two decimals, include a 0 before the decimal if necessary, and do not include units (i.e. O.XX)Extinction Match the following items. NOTE: If you want to change your selection, you'll need to delete the one you already chose. After you delete it, the list of choices will pop back up and you can make a different choice. Sudden, dramatic loss of biodiversity mass extinction Routine loss of biodiversity; about 1 per million species years background extinctionThe power-based relationship between number of species and area (i.e. S = cA^z) is very well documented. Which of the following processes might be contributing to this relationship? (Select all that apply.) Immigration Evolution Extinction None of the above
- The graph below shows the population of three different families of marine organisms along five different mass extinction events. Each colour on the graph represents a family of organisms, and the Y axis shows how many species belong to that family. a. What stage of population growth is displayed at point ‘0’ on the graph above? b. The Extinction Event that occurred at point 3 was particularly significant. Using the graph, explain how this event impacted each marine family. c. The extinction events mapped above had significant impact on marine life. What type of event could have a similar impact on the human population?Define extinctionWhat seems to be a common occurrence with all mass extinction events? Rising CO2 Rising water pH Rising temperatures None of the above
- Can someone help explain this from a mathematical perspective? Consider a species that occupies a large, but fixed, number of islands. The distribution of the species across all islands is maintained by a balance between local extinctions and local colonization events. Devise a model for the relationship between the fraction of islands occupied by the species and time. Be clear to outline the assumptions you make and be sure to describe your key predictions.There have been five main mass extinctions. Match each mass extinction event to its description. 1. Permian extinction 2. Cretaceous-Tertiary extinction 3. Triassic extinction 4. Devonian extinction 5. Ordovician extinction a. This extinction was most likely due to a change in sea level. During this event, about 60% of all marine species were eliminated. b. This is the best-known mass extinction. It eliminated most large animals, including the dinosaurs. c. This was the most severe extinction event. About 96% of life on Earth died during this event. d. This extinction was most likely caused by climate change. About 80% of land animals died during this event. e. This extinction was most likely due to a change in sea level. It especially affected coral reefs.Discuss Triassic-Jurassic Extinction. Make sure to discuss the possible causes of the extinction, the index fossil that marked the extinction event, and finally, at least two species (can use the common name) that survived after.
