- An ecosystem that is highly capable of recovering and regenerating through secondary succession after a disturbance is exhibiting high resilience. True FalseWhite-winged doves highly value the few, large, sweet fruits produced by saguaros. While ignoring each other, they race to eat them all. This is an example of: Question options: Interspecific exploitation competition. Interspecific interference competition. Intraspecific exploitation competition. Intraspecific interference competition.As environmental conditions change, communities continue to go through succession toward a predictable climax community. True False

- Long-term fertilization of plant communities often results in increased species richness. True FalseCompare and contrast the three main types of exploitativespecies interactions. How do predation, parasitism,and herbivory differ?Giraffes are herbivores found in Africa. They prefer to eat twigs and leaves from acacia trees. This type of producer–consumer relationship can be described as a predator–prey relationship or parasitism. Explain an instance the giraffe–acacia tree relationship would be parasitic and not predatior-prey.
- Which statement about the classic competition experiments involving two Paramecium species is FALSE? The experiment involved interspecific competition. The experiment involved exploitation competition. Each species, when grown alone, exhibited logistic growth. When grown together, the species exhibited logistic growth, but each reached a lower carrying capacity than when it was grown alone.During indirection interaction, one species affects another through a third, intermediary species. For example, beavers fell cottonwood threes which then produce stump sproutsz Beetels prefer consuming high nutrition sprout leaves. In this relationship, who gains, who losses, who is not affected, and what is the relationship and between whom?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 does this affect management policies aimed at increasing biodiversity and proliferation of inter and intra population and interspecies variation. B) Endangered species are defined by low growth rates (r) and low K (reflecting high demand for resources). What are the implications of both these factors on the outcome of competition scenarios, especially the most common scenario of alternate stable states?
