Which of the following accurately describes a trophic cascade? O a Sunflower stars are the primary predator of sea urchins in Northern California. The sunflower stars have an INDIRECT, POSITIVE IMPACT on the sea urchin's main prey, bull kelp. Ob. Sea otters prey directly on kelp and keeps kelp populations in check. O c. Sunflower stars are the primary predator of sea urchins in Northern California. The sunflower stars have a DIRECT, POSITIVE IMPACT on the sea urchin's main prey, bull kelp. Od. The presence of Pisaster seastars benefits Mytilus mussels, a primary producer.

Figure 19.6 If the major food source of seals declines due to pollution or overfishing, which of the following would likely occur? a. The carrying capacity of seals would decrease, as would the seal population. b. The carrying capacity of seals would decrease, but the seal population would remain the same. c. The number of seal deaths would increase, but the number of births would also increase, so the population size would remain the same. d.

1. Examine the food webs for Lake Victoria, East Africa (fig 31.2 a,b) before and after the introduction of the Nile perch (Leveque 1995). Calculate the mean food chain length, percent of trophic groups at various levels, and connectance for each food web.

The following is NOT true about trophic levels Animals capable of feeding at many trophic levels will be able to survive if portions of their food supply are decreased or eliminated Secondary consumers belong to the third trophic level Primary consumers belong to the first trophic level Each stage through which energy travels is called a trophic level
Predation influences demography and individual fitness in some ecological settings. Discuss scenarios where predation play an important ecological role nad others where it appears to be less importany
What is accurate about the nature of competition between species? Choose All That Apply O it takes energy away from other functions of the organisms involved Otraits that reduce competition are generally selected for it is less intense the more the niches overlap overtime it could potentially result in resource partitioning
CA least tern ENDANGERED ANIMAL is CA least tern questionbases on the bird CA least term Reasons for Endangerment Explain the various factors that have led to this species’ current plight. Expand on these points individually, based on your species’ unique story. Domino Effects As we’ve learned, species are not islands unto themselves; they are integrated with many other organisms in trophic relationships, mutualisms, competition, etc. How is the absence of this species (or its lowered population size) likely to impact the other members of its habitat? (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?
