- How do the tube worms at the hydrothermal vents survive? a The tube worms burrow into the sediment on the sea floor and find smaller worms and clams to eat. b The tube worms swim from vent to vent, looking for mats of bacteria that they can scrape off the rock with their red, bushy plumes. c The tube worms use their red bushy plumes to grab and devour small organisms like tiny shrimp. d They have a symbiotic relationship with bacteria that live inside them and provide their nutrition.arrow_forwardAs the human population grows and as the average rate of resource use per person rises, water shortages in many parts of the world are becoming more severe and, thus, more of a global concern. It is predicted that humans will have no cholce but to reduce their water footprints in the near future. A water footprint is an estimate of how much water it takes each year to meet the needs of a person, a population, or a country. Currently, the total water footprint of U.S. citizens is 2,487 cubic meters per year per capita (m/yr/ca). This is equivalent to 657,000 gallons/yr/ca, or more than 16,000 bathtubfuls of water per year! From what you know about water footprints, which of the following makes up the majority of the average American's water footprint? O Water used in washing machines O Water used in the production and delivery of food and consumer goods O water consumed from using household toilets and showersarrow_forward2.
