Food Webs Food webs are helpful diagrams to understand the relationships of organisms within a biological community. Answer the following questions using the food web below. Baleen whale Smaller toothed Sperm whale whales Penguins Elephant seal Leopard seal Other birds Fish \/ Other seals Squid Krill Other herbivorous zooplankton Carnivorous zooplankton Phytoplankton Which of the following food chains is represented in this food web? O plankton > herbivorous zooplankton > fish > penguin > smaller toothed whale O herbivorous zooplankton > krill > other birds > baleen whale O phytoplankton > krill > other seals > smaller toothed whale > baleen whale O plankton > carnivorous zooplankton > fish > leopard seal > smaller toothed whale

A niche is loosely defined as an organism's role in its environment, which can include factors such as feeding preference, nesting behaviors, mating behaviors, method of obtaining prey, and local habitats. Keeping Gause's law in mind, do some research on the California red-legged frog and the North Pacific tree frog (use wiki or another Google search). Create a chart comparing the two with respect to their niche or lifestyle that can explain how these two frogs can co-exist in the same ecosystem.

Using the image, choose three possible outcomes a change in the marine ecosystem could have on predatory animals that eat small shellfish. O The predatory animals that eat the shellfish will move on to find food sources elsewhere. O The predatory animals will most likely die due to a lack of food sources necessary to sustain life. There will be no change to the predatory animals due to a decrease in the shelled marine life. The predatory animals will adapt to the change in food sources and eat alternative prey that is available. O The predatory animals will produce more offspring that will be able to survive in the changing ecosystem.

The resource page discusses an increasing threat of nuisance flooding in North Carolina. To understand what nuisance flooding is, you have to have a basic understanding of tides. How are tides generated and propagated around ocean basins? Explain how the factors that control tides change over the course of one month and tie that back to the problems with nuisance flooding. Please be sure to reference your article (include information about it) in your answer and define any scientific terms your audience may not know.

Please help me answer this in 10 sentences only. In the Convention of Biological Diversity (CBD), the precautionary principle read “when there is a threat of significant reduction or loss of biological diversity, lack of full scientific uncertainty should not be used as a reason for postponing measure to minimize or avoid threat”. What is the application of this principle to straddling fish stocks and migratory fishes? Thank you very much for your help

ENDANGERED ANIMAL is  CA least tern bird  1-2 bases on the  CA least tern bird   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?

Read the article given below and answer the questions that follow:    Recent increases in populations of seabirds that were depleted severely during the middle of the twentieth century demonstrate the efficacy of conservation strategies that work within the context of local culture. Along the North Shore of the Gulf of St. Lawrence in Quebec, Canada, direct exploitation and disturbance of breeding seabirds caused severe declines for several species between 1955 and 1978, including 84 percent and 76 percent declines for Razorbill and Atlantic Puffin, respectively. Significant reductions also occurred for populations of Common Eider (Somateria molissima), Common Murre (Uria aalge), and Black Guillemot (Cyphus grylle).   Research by the Quebec-Labrador Foundation, a nonprofit conservation organization, into root causes of the population declines along a 400-km stretch of coast revealed conflicts between conventional enforcement of migratory bird regulations and cultural norms.

INTRODUCTION: Quadrat sampling is a classic tool for the study of ecology, especially biodiversity. In general, a series of squares (quadrats) of a set size are placed in a habitat of interest and the species within those quadrats are identified and recorded. QUESTION: What are the advantages and disadvantages of a quadrat sampling method?

OBSERVATIONS • Sea otters feed significantly on sea urchins, often keeping urchin abundance 'in check'. • Sea urchins feed heavily on kelp, decimating kelp forests when urchin abundance is high. • Kelp forests protect the shoreline from coastal erosion by buffering wave action. • Orcas have been observed feeding on sea otters in the kelp forests of western Alaska.

LAB: THE LESSON OF THE KAIBAB INTRODUCTION: The environment may be changed by the things within the biotic community, as well as relationship between organisms and the nonliving environment. The carrying capacity of an ecosystem is the maximum number of organisms that an area can support over time. The density of a population may cause huge changes in the environment so that the environment becomes unstable for the survival of that species. Humans can mess up natural selection and have either a positive or negative effect. OBJECTIVES Graph data on the Kaibab deer population of Arizona from 1905-1939. Analyze the factors that caused the changes in the deer population. PROCEDURE: Before 1905, there was an estimated 4000 deer on almost 30,000 hectacres of land on the Kaibab Plateau in Arizona. The average carrying capacity of the land at that time was estimated to be about 30,000 deer. Being concerned about the low number of deer, President Theodore Roosevelt created the Grand Canyon…

The biodiversity of the planet is rapidly being depleted. Scientists' efforts to monitor and protect biodiversity are being aided by a slew of new technologies and the volunteer work of ordinary citizens. To help scientists in their conservation work, new technologies have been developed. For example, Footprint identification technique (FIT) uses photo digitization to identify the footprints of large cats and other mammals, which will allow collection of data about these animals in a noninvasive manner. Other noninvasive data collection techniques include vocalization identification, drones, DNA analysis, and camera-trapping. Apps such as eBird and iNaturalist allow amateurs to record their observations in open-access online databases for further analysis. Smartphones and drones could be useful in collecting data to prevent poaching, although such technologies are in their infancy and still not widely available in developing countries. Remote sensing could be used to monitor changes in…
