OCEAN TRENCHES (which statement is incorrect)

• The very deepest part of the ocean

• No light in this area

• The water pressure here is very high

• Home to many living things

Answer explanation

The correct answer is 'Home to many living things' because ocean trenches are not typically home to many living organisms due to extreme conditions like high pressure, lack of light, and low nutrients.

What are trenches in the context of the ocean floor?
