Oceanic Ecosystem and Environmental Adaptations Quiz

The Pacific Ocean is the largest and deepest ocean on Earth.

Seagrasses play a primary role in the oceanic ecosystem by stabilizing sediments.

Phytoplankton are microscopic organisms that form the base of the marine food web through photosynthesis.

Mangrove forests play a primary role in the coastal ecosystem by preventing erosion.

Sunlight serves as the primary source of energy for most life in the ocean through photosynthesis.

Bioluminescence is a deep-sea adaptation that allows marine organisms to produce light.

Thermohaline circulation describes the movement of warm surface water towards poles and cold, nutrient-rich water rising from the depths.

Anglerfish are known for their ability to produce light through bioluminescence.

The Estuarine zone is where freshwater from rivers mixes with salty ocean water.

El Niño is characterized by the periodic warming of sea surface temperatures in the central and eastern Pacific Ocean.

Photosynthesis is the process where marine organisms convert sunlight into chemical energy for survival.

Ocean acidification is the process where oceans absorb carbon dioxide from the atmosphere, leading to increased acidity.

The Abyssopelagic zone receives the least sunlight and is marked by high pressure and low temperatures.

Climate change poses the main threat to coral reefs worldwide through ocean warming and acidification.

The Hadopelagic zone is characterized by constant darkness, extreme pressure, and near-freezing temperatures.

Countercurrent heat exchange helps marine mammals like whales to dive to great depths by conserving heat.

The Coriolis Current is responsible for clockwise circulation in the Northern Hemisphere and counterclockwise circulation in the Southern Hemisphere.

The main factor contributing to the formation of coral reefs is the deposition of calcium carbonate by coral polyps.
