- Urgent please The larval stage of dragonflies live in water. The graph below shows the populationdensity of two species of dragonflies larvae in a pond over a period of 20 days.Based on this graph, what is happening between these two species in this particularpond? 1.Resource partitioning2.Niche realization3.Competitive exclusion4.Ecological character displacementConservation Biology Quiz 2 4. Predator- predator inter a prey h Conservation Biology Quiz 2 2. Community - Competition. Competition between species on the same trophic tier leads to four potential outcomes, 3 are deterministic (zero sum games where one species goes extinct and the other maximizes their growth to balance at the carrying capacity) and one where both competitors survive, but neither does well. a. This dynamic suggests that extirpation (local extinction) of populations is a far more likely outcome than co-existence. How, in your opinion, does this affect management policies aimed at increasing biodiversity and proliferation of inter and intra population and interspecies variation. Reason your point of view.

(If findings specific to this point are available, please include them – otherwise, I’m asking you to speculate based on what you’ve learned about the biology of this organism.) Conservation Efforts Discuss past, current, and proposed efforts to conserve this species. Are these strategies effective? Are they realistic? What is the outlook for this organism?There are two types of life strategies used by organisms to survive in their environment. 1. K-selected strategy - growth rate is near the carrying capacity 2. r-selected strategy - growth rate is near biotic potential Match the characteristices below to the life strategy they represent J-cruve Logistic Growth Long life span Few offspring
