What is a marine ecosystem?

Back

A marine ecosystem is a complex community of organisms and their environment in oceanic or coastal areas, characterized by interactions among marine life and physical factors.

Front

What percentage of the Earth's surface is covered by marine ecosystems?

Back

70% of the Earth's surface is covered by marine ecosystems.

Front

What are polar marine ecosystems?

Back

Polar marine ecosystems are marine environments found in polar regions, characterized by cold temperatures and unique species adapted to these conditions.

Front

What is the euphotic zone?

Back

The euphotic zone is the upper layer of the ocean where there is enough light for photosynthesis to occur.

Front

What is the benthic zone?

Back

The benthic zone is the ecological region at the lowest level of a body of water, including the sediment surface and sub-surface layers, where many invertebrates live.

Front

Why are few plants found on the bottom floor of the ocean?

Back

Few plants are found on the ocean floor because sunlight does not reach this depth, limiting photosynthesis.

Front

What is the intertidal zone?

Back

The intertidal zone is the area of the shoreline that is exposed to the air at low tide and submerged at high tide, hosting unique organisms adapted to these conditions.

Front

What is the dysphotic zone?

Back

The dysphotic zone is the layer of the ocean where light is insufficient for photosynthesis, typically found below the euphotic zone.

Front

What role do decomposers play in marine ecosystems?

Back

Decomposers break down dead organic matter, recycling nutrients back into the ecosystem, which supports new growth.

Front

What are coral reefs?

Back

Coral reefs are diverse underwater ecosystems held together by calcium carbonate structures secreted by corals, providing habitat for many marine species.
