Chapter 28, Problem 2CT
Summary Introduction
To review:
The production of sulfur from hydrothermal vents and whether the production is enough and harvesting this sulfur would harm the ecosystem.
Introduction:
A hydrothermal vent is a fissure in the planet’s surface, which spewed out the geothermally heated water. This warm water is laden with the minerals. They are most commonly found near the volcanically active areas. Different types of microbes are present in the surroundings that under anaerobic conditions can utilize the sulfur by oxidizing it.
An entrepreneur decides to harvest the sulfur from the Pacific Ocean from the microorganism. One group of microbiologist disagrees as they think that this will damage the fragile ecosystem by depleting the usable sulfur but another group believes that vent produces sulfur in much more amount than it is required by the clams and tube worms.

D) temperature in Maine is too low. 5) In the Galapagos, the medium ground finch, Geospiza fortis, and large ground finch, Geospiza magnirostris, both live on the island Daphne Major. Scientists have studied these species and recorded detailed information, which includes observations about their diets and beak sizes. After a long period of drought, there were very few seeds available for both species to eat, and many of the finches died. The scientists who studied these birds observed that the average size of G. fortis beaks decreased dramatically during the years after the drought, whereas the average size of G. magnirostris beaks increased. G. fortis became specialized in eating very small seeds, whereas G. magnirostris…arrow_forwardWhich of these statements describes an accurate model for how carbon dioxide and oxygen levels change within the ocean over time?

- Why the population of birds are getting declined in an area where DDT had been used extensively?arrow_forwardAt a global scale, harmful algal blooms (HABS) are appearing in many places, often new places, and lasting longer than previously recorded. Across Florida, the occurrence of algal blooms, caused by various species of phytoplankton, has been intensifying. In the summer of 2016, a state of emergency was declared because a toxic cyanobacterial bloom occurred in Lake Okeechobee which spread into and throughout the St. Lucie River and Estuary. Water samples collected during the bloom helped identify a limiting nutrient. 1. Data from a Burger et al. (2004) indicate that mercury levels in Florida gar, top-level predators, from Lake Okeechobee were not higher than mercury levels of fish muscle from other locations in the United States. However, mercury levels in the livers of Florida gar were above the level considered safe for human consumption. a. Explain why this is good news for people who fish in Lake Okeechobee. b. Explain why this is bad news for non-human consumers of fish, and how it…arrow_forwardThe graphs show how the cloudiness of the water at two different sites varied over a period of one year. Site A had a low nitrate concentration. Site B had a high nitrate concentration. (i) Describe and explain the effect of increased nitrate concentration on algal growth. (ii) Algae do not live long. Explain why the presence of large numbers of algae results in a fall in the amount of oxygen dissolved in the water. (iii) There are very few submerged water plants at Site B. Use (iii) the graphs to suggest how placing a speed limit on boats might allow submerged water plants to become re-established at Site B.arrow_forward
