The Endangered Species Act (ESA) of 1973 has helped to slow the destruction of habitat and the loss of species in the United States. There are now many success stories of animals/plants that were on the edge of extinction and now are returning. Even with the success stories there are many who criticize ESA. I want you to give at least 2 examples (with explanation) that show the success and need for The Endangered Species Act. And give 2 reasons why ESA is still criticized after all these years.
Which of the following does NOT describe an externality? A: A flower farm is located in a semi-urban part of town. The flowers attract pollinators that help nearby farms but also provoke allergies for some of the local residents. B: A cranberry farm releases acidic water into a nearby river that is an important habitat for many native species. C: A firm voluntarily adopts a new technology that reduces how much pollution it emits into the air, resulting in cleaner air for everyone. D: An industrial-scale farm uses high amounts of pesticides which reduces the farm’s ability to produce food over the longer term.
In a coevolutionary arms race, after a plant evolves a novel chemical defense against an herbivore, a the plant can be expected to outcompete all other plants in the same environment. b the herbivore can be expected to evolve resistance to the plant's defense. c the herbivore can be expected to disperse to new habitats. d the herbivore can be expected to go extinct. e the plant can be expected to colonize new habitats.
A biologist is studying the way in which the environment is affecting the reproductive rates of a particular tree species, Acer saccharum, what type of ecology best describes this research? Group of answer choices a. Community b. Landscape c. Individual d. Population e. Ecosystem
The grassland ecosystem of Montana is being studied for its resilience as the population of its keystone species, the prairie dog, has declined in recent years. Four plots are established, two that still contain populations of prairie dogs and two that no longer have prairie dogs due to outbreaks of plague. A survey is done measuring the total number of producers (number of plants) and the diversity of producers (number of species) of each plot. The data are summarized in the table. Based on this data, which of the following correctly describes how the total number of plant and plant species will change over time in these plots? A - Plots 2 and 3 will show equal decline in plant and plant species due to the lack of a keystone species. B - Plots 1 and 4 will show a decline in plant and plant species due to an increase in the number of prairie dogs consuming the producers. C - Plots 2 and 3 will show a decline in plant and plant species, but plot 3 will show a slower decline due to a…
Geographer, historian, and author Jared Diamond (1987) once referred to agriculture as "the worst mistake in the history of the human race." Given what you have learned about the health consequences of the domestication of plants and animals for humans, how would you respond to his statement? You may find this article helpful in your discussion response: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4163920/
Which of the following statements most accurately describes the example of species interactions for ants, plants and aphids Question 2 options: The burdock plant is negatively affected by a heavy aphid investation, the ants are negatively affected by the aphids and aphids are positively affected by the ants. The burdock plant is negatively affected by a heavy aphid investation, the ants are positively affected by the aphids and aphids are not affected by the ants The burdock plant is negatively affected by a heavy aphid investation, the ants are positively affected by the aphids and aphids are positively affected by the ants. The burdock plant is not affected by a heavy aphid investation, the ants are positively affected by the aphids and aphids are positively affected by the ants.

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.
You're growing cabbage and have noticed your plants have lots of insects and disease. Explain how you could use integrated pest management to help your crop be successful (either for the current season or in the future).
Which of the following situations has revealed that mutualistic interactions can evolve from prior parasitic relationships? A. Yucca plants are pollinated only by moths of the genus Tegeticula; however, some of the moth species 'cheat" by laying eggs on seeds without pollinating the plant. B. Large-sized lice of the genus Columbicola tended to live on larger species of pigeons. Body size matching had a significant effect on the ability of lice to escape defensive preening by the host bird. C. The nonvenomous yellow-eyed salamander has the same coloration as the toxic California newt. Related nontoxic salamanders which do not mimic the newts are prone to attacks by predators. D. Glochidion trees and Epicephala moths are in an obligate mutualism with each other. Significant cospeciation led to an increase in diversity of the two species.
Ants form associations with many types of other insects that feed on the sap of plants.One of these types of insects is an Ecuadorian tree hopper. You think that theassociation between the ants and treehoppers might be a mutualism. Tree hoppersfeed on plants, and the ants feed on the “honeydew” that is excreted as waste by thetreehoppers. In return, the ants may protect the treehoppers from predators les and controls should follow from your methods.QUESTIONS1.
