Give your response to the following statement: “Eventually, all species become extinct. So it does not reallymatter that the world’s remaining tiger species or atropical forest plant are endangered mostly because ofhuman activities.” Be honest about your reaction, andgive arguments to support your position.

Is the species a generalist or a specialist and how does this niche impact the species of the wild.  The giant panda, native to China, and the raccoon, native to North America, share a common ancestor. However, their current status in the wild is anything but common. Raccoons are thriving. Opportunists by nature, raccoons forage on a variety of plants and animals in their ecosystem. Highly inquisitive and intelligent, raccoons use their opposable thumbs to crack open shells, investigate dens, and sift through rocky streams in search of crayfish. Although their habitats are shrinking, raccoons have adapted well to human encroachment and will actively seek food and shelter among the human community

The Colorado potato beetle has a history of pesticide resistance. The graph shows the number of chemical insecticides used in agriculture that the Colorado beetle population has become resistant to from 1950 to 2010. It took longer for the population of potato beetle to develop a resistance to some insecticides. However, by 1990, the Colorado potato beetle population had developed a resistance to 35 different kinds of insecticides, and farmers ran out of insecticides they could use to control the beetle population. A new type of insecticide was introduced in 1995. 60 40 30 20 10 1960 1970 1980 1990 2000 Year of Report Which of the following best describes what happened from 1965 to 1975 and again from 1995 to 2000 to the insecticide resistance of the beetle population? The Colorado beetle gene pool for insecticide resistance was identical and the insecticide had no effect on the beetle population, which is why it continued to increase. The introduced insecticides were effective for a…

How would you respond to someone who says that because extinction is a natural process, we should not worry about the loss of biodiversity when species become extinct largely because of our activities?

In not more than 4 paragraphs. What is the relationship of each predation in the extinction of some animals? Discuss.

I’m having hard time understanding this questions can you please help?

ENDANGERED ANIMAL is  CA least tern bird  1-3 bases on the bird 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?

Question 73 Match the description to the specific type of symbiosis. "win-win" symbiosis, both partners benefit [Choose] [Choose ] "win-lose" symbiosis, one partner benefits, the other is harmed utopianism mutualism "win-neutral" symbiosis, one partner commercialism benefits, other neither benefits nor is harmed commensalism parasitism

Respond to the following statements in reference to the five kinds of species interactions listed below. An example of this interaction is that between an epiphyte and its host. In this interaction between two species, both species are harmed to some degree. In this interaction, both species benefit. In this interaction, one individual or species is usually killed while the other benefits by eating it. In this interaction, one species is harmed but usually not killed, to the benefit of the other that lives on or in it. a. Competition b. Predation C. Mutualism d. Commensalism e. Parasitism

Choose the best answer. When the environment changes dramatically: All of these answers are true many species may go extinct. O a specialist species may evolve into several new species. O a generalist species may survive by exploiting various resources.
