Oceans Part 2 Review

Hydrothermal Vents

• occur in the deep ocean Abyssal zone around mid-ocean ridges.

• Organisms create energy through chemosysnthesis.

• Produces hydrogen sulfides that are consumed by microbes to create energy through chemosynthesis.

Multiple Choice

Which of the following best explains how organisms around hydrothermal vent get energy?

• Algae and Bacteria produce energy through photosynthesis.

• Dead plant and animals produce energy through decomposition.

• Hydrothermal vents produce energy through chemical reactions.

• Light comes from the core of the earth.

Multiple Choice

Which ocean zone contains hydrothermal vents.

• Deep Zone (Abyss)

• Shallow Zone (Twilight)

• Surface Zones (Sunlight Zone)

• Midnight Zone

Life around the hydrothermal vents

• Scientists discovered tubeworms and other organisms.

• These organisms get energy through a process known as chemosynthesis.

• Chemsynthesis is the process of creating energy through chemical reactions.

• Hydrothermal vents provide Hydrogen Sulfide that is used during chemosynthesis to create energy for organisms.
