Question

Living in the dark

According to the author, what is the main obstacle to exploring the ocean depths? Explain why, citing evidence from the text..

Answer 1

The primary obstacle to exploring ocean depths is the lack of light in the aphotic zone, affecting photosynthesis and requiring adaptations like chemosynthesis.

Step-by-step explanation:

According to the author, the main obstacle to exploring the ocean depths is the lack of light beyond certain depths, specifically in the aphotic zone. This zone begins at about 200 meters depth where insufficient sunlight penetrates for photosynthesis to occur. Therefore, organisms living there have had to adapt to survive without light, relying on processes like chemosynthesis. This limitation poses a significant barrier to ocean exploration because it affects the entire food chain and the feasibility of sustaining human life underwater for extended periods.

Answer 2

The correct answer to this open question is the following.

Unfortunately, you did not attach the excerpt or the article. We do not know who the author is

So we can help you to answer in the following general terms.

The main obstacle to exploring the ocean depths is the excessive pressure the sea exerts on humans and all the equipment needed to explore the depth of the oceans and the corrosive effect of the water.

The pressure is too dangerous for humans because it has a direct effect on the lungs of humans.

Another costly reason is the power to turn the equipment needed to explore the depth of the sea. Power resources are too expensive and their duration, so limited.
