2. deepest, very cold region of the open ocean
3. ocean - floor area consisting of sand, silt, and dead organisms
4. open - ocean zone shallow enough for sunlight to penetrate
5. open - ocean zone through which sunlight cannot penetrate

ecosystem:

benthic zone
photic zone
abyssal zone
intertidal zone
select choice

Explanation:

1. The intertidal zone is the narrow band of shoreline where the ocean and land meet, alternately submerged and exposed, home to changing communities.
2. The abyssal zone is the deepest, very cold region of the open - ocean.
3. The pelagic zone (photic part) includes the open - ocean zone shallow enough for sunlight to penetrate.
4. The benthic zone is the ocean - floor area consisting of sand, silt, and dead organisms.
5. The aphotic zone is the open - ocean zone through which sunlight cannot penetrate.

Answer:

1. Narrow band of shoreline where the ocean and land meet that is alternately submerged and exposed and is home to constantly changing communities - Intertidal zone
2. Deepest, very cold region of the open ocean - Abyssal zone
3. Ocean - floor area consisting of sand, silt, and dead organisms - Benthic zone
4. Open - ocean zone shallow enough for sunlight to penetrate - Photic zone
5. Open - ocean zone through which sunlight cannot penetrate - Aphotic zone
