Question

what starts the food webs in the deep ocean where there is no sunlight? * 1 point
decomposers which break down dead organisms that sink to deep water
chemosynthetic bacteria that produce food using chemical energy
scavengers which eat dead organisms that sink to deep water
detritivores which break down marine snow that drifts around the ocean
algae that stores food it made at the surface using sunlight

the area where the ocean meets the land, between high tide and low tide lines, is what zone? answer using only one or two words. make sure to spell them correctly to earn credit.

your answer

what term or phrase do we use to refer to regions of aquatic habitats that are not near the shore or close to the bottom? answer using only one or two words. make sure to spell them correctly to earn credit.

Explanation:

• For the first question: In deep - ocean environments with no sunlight, photosynthesis (which requires sunlight) cannot occur. Chemosynthetic bacteria use chemical energy (such as from hydrogen sulfide) to produce food, which is the basis of the food web. Decomposers break down dead matter but are not the primary producers. Scavengers eat dead organisms but are consumers. Detritivores break down detritus (like marine snow) but are also consumers. Algae need sunlight for photosynthesis, which is not available in the deep ocean.
• For the second question: The intertidal zone (also known as the littoral zone) is the area between the high - tide and low - tide lines where the ocean meets the land.
• For the third question: The pelagic zone refers to regions of aquatic habitats that are not near the shore (not benthic or littoral) and not close to the bottom.

Answer:

• First question: chemosynthetic bacteria that produce food using chemical energy
• Second question: intertidal zone
• Third question: pelagic zone
