The food web above represents feeding relationships in a biological community near a deep-sea hydrothermal vent. Hydrothermal vents 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. Based on an analysis of the food web, an observation that deep-sea bacteria consume molecular hydrogen (H2) is most relevant to resolving which of the following apparent contradictions?Some organisms rely on energy captured from inorganic compounds to drive basic biological processes.
Some deep-sea organisms appear to be primary consumers, but no plants live near the hydrothermal vents.

Answers

Answer 1
Answer:

Some bacteria and archaea (unicellular organisms), which are known as chemoautotrophs and are typically found in hydrothermal vents in the deep ocean, are examples of chemolithotrophs. These organisms build biomass by the oxidation of inorganic chemical substances. Thus, option A is correct.

What organisms rely on energy from inorganic compounds?

Autotrophs are organisms that derive their energy from chemical interactions or the sun. They are also known as producers since they create organic molecules from simple inorganic substances and energy.

Some organisms use the energy that inorganic molecules release to power their core biological functions.

Therefore, Some organisms rely on energy captured from inorganic compounds to drive basic biological processes.

Answer 2
Answer:

The observation of bacteria consuming molecular hydrogen helps explain how energy flows through this ecosystem and how primary consumers can exist without relying on photosynthetic plants, which cannot thrive in the absence of sunlight near hydrothermal vents.

The observation that deep-sea bacteria consume molecular hydrogen (H2) is most relevant to resolving the apparent contradiction that "Some organisms rely on energy captured from inorganic compounds to drive basic biological processes" and "Some deep-sea organisms appear to be primary consumers, but no plants live near the hydrothermal vents."

The process by which these bacteria consume molecular hydrogen and utilize it to produce organic compounds through chemosynthesis can provide an explanation for the energy source that supports the primary consumers (in this case, mussels) near the hydrothermal vents. Chemosynthesis allows organisms to generate energy and organic matter from inorganic compounds, such as H2, H2S, and CH4, which are abundant near hydrothermal vents. These primary consumers (like mussels) can then feed on these chemosynthetic bacteria, forming the basis of the food web in this unique ecosystem.

"Over the years, the forest cover in a particular ecosystem was reduced from about 50% to 20%. What would be the MOST LIKELY effect of this?A) The loss of moisture from the soil would be reduced.
Eliminate
B) Herbivores would be forced to change into carnivores.
C) The flow of energy in the ecosystem would be affected.
D) The exchange of carbon dioxide in the ecosystem would increase"

Answers

The correct answer is option C

If the forest cover in an ecosystem is reduced from 50% to 20%. The most likely effect is that the flow of energy in the ecosystem would be affected.The forest means the green plants that are also known as the producers of the ecosystem and they transfer energy to the consumers and the ecological balance is maintained. If there will be less producers then the flow of energy in the ecosystem will be affected.

What difference did Darwin notice among the finches

Answers

He saw that they all had different sizes and shape beaks, he believed that they adapted to their environment. In one place the finches had huge beaks especially made for cracking nuts. In another they could have shorter and thinner beaks made to eat insects off the ground like worms. 
Darwin found evidence for evolution! 
:)
They were different colors, sizes, etc. which brought his theory that all animals have different characteristics which makes them unique in their own way.

The original population of brown spotted deer declined drastically after their forest habitat was flooded. After frantic efforts over three decades by the forest authorities to revive the dwindling population, it did bounce back. Now the deer population is as huge as it was three decades ago, but it shows a decreased amount of genetic variations. Which factor could be responsible for this microevolution?

Answers

Evolutionary bottleneck. The current population is descended from the few deer that existed at the population's lowest level.
A. Convergent evolution produces organisms with different adaptations but common ancestry, whereas adaptive radiation produces organisms with similar adaptations but different ancestry.

Which of the following is always an important part of an experiment?1.making a working model

2.observing things in nature

3.making drawings of things observed

4.identifying and controlling variables

Answers

The most important part of an experiment would be; identifying and controlling variables.

In order to set up an experiment, you need to test the specimen(s) with and without a curtain variable. That is what makes an experiment a test.

Answer:

identify and controlling variables

Explanation:

lack of awareness of control variables can lead to faulty result or what are called "confounding variables" additionally, noting control variables makes it easier to reproduce and experiment and establish the relationship between the independent and the dependent variable
