The food web above represents feeding relationships in a biological community near a deep-sea hydrothermal vent. Hydrothermal ve

nts are geysers on the seafloor that gush super-heated, mineral-rich water. The seawater surrounding hydrothermal vents typically contains carbon dioxide (CO2), molecular hydrogen (H2), hydrogen sulfide (H2S), and methane (CH4). Sunlight, however, fails to reach the seafloor where deep-sea hydrothermal vents are located.
As part of an investigation, researchers collected living specimens from an area near a deep-sea hydrothermal vent. Mussels in the collection were found to be dependent on molecular hydrogen in seawater. Also, the researchers discovered multiple species of bacteria living in the gills of the mussels. Mussels use gills for filter-feeding and gas exchange with the surrounding seawater. On the basis of their experimental results, the researchers hypothesized that some bacteria living in the gills of the mussels are capable of chemosynthesis. Which of the following best explains how biological communities near deep-sea hydrothermal vents can exist in a habitat lacking sunlight?

Answer: the bacteria in the habitat are the primary producer that relies on chemosynthesis (ability of organisms to produce their own food by anabolism of chemicals). Due to the the presence of h2S (hydrogen sulphide), the organisms are most probably Sulphur bacteria, liberating hydrogen as by products. This ability means that the bacteria can flourish without sunlight. The mussel are the secondary filter that feeds on the flourishing bacteria population. This build up to form a community whose primary energy source is from the minerals liberated by the vent and hence doesn't require sunlight.

Which organisms synthesize carbohydrates, and in which cell organelle(s) does this synthesis occur?
ad-work [718]

Answer:

C

Explanation:

Green Plants are the main producers of starch as carbohydrate.In order to carry out this  special organelle Chloroplast are specially adapted  for this purpose,

Green plant are made up of Chlorophyll which are the green pigments that for trapping sunlight for the synthesis of starch to occur.

Photosynthesis is the process of synthesis of the starch.It involves the reaction of C02 with water  in the presence of sunlight  and enzymes to give oxygen as the byproduct, and Starch( carbohydrate) as the main product.

This process occur in two pathways the light dependent pathways and the light independent pathways,

Green plant and some organisms phytoplankons,algea are capable of producing starch  through photosynthesis because of the green pigment they possess.Therefore they are said to be Autothrophic.

Scientific question: Why does a dog circle its bed before lying down?
SVEN [57.7K]
In the scientific method first of all is you need to identify the problem, the problem to your question is why does the dog circle its bed before lying down. Second is the observation to gather some data, you need to observe the dog if what could be the possibility the the dog may do that action. The third is the pre hypothesis, you need to came up with an idea why does the dog do such and action for example the needs to find a correct spot to make itself comfortable and lastly the hypothesis, this should answer to your question or your problem. So my hypothesis is that dogs are one of the animals that are those difficult to find a place to sleep and some of that kind of animals are cat, before they lay on their bed, they have to circle to find a spot that could fit its body to be more comfortable when the dog sleep
