What implications does the second law of thermodynamics have for biological systems quizlet?

What implication(s) does the second law of thermodynamics have for biological systems? A constant supply of energy is necessary for maintenance of biological systems.

Which of the following does not recycle repeatedly through Earth’s ecosystems?

Thus, the correct answer is 'Energy.

How do the organisms living around Yellowstone hot springs get energy?

How do the organisms living around Yellowstone's hot springs get energy? From chemosynthesis.

Which of the following cycles does not involve an atmospheric phase of matter?

1 Answer. The phosphorus cycle does not have an atmospheric component.

Which implications does the Second Law of Thermodynamics have for biological systems?

The Second Law of Thermodynamics states that when energy is transferred, there will be less energy available at the end of the transfer process than at the beginning. Due to entropy, which is the measure of disorder in a closed system, all of the available energy will not be useful to the organism.

Which of the following is a description of an example of the Second Law of Thermodynamics?

Examples of the second law of thermodynamics For example, when a hot object is placed in contact with a cold object, heat flows from the hotter one to the colder one, never spontaneously from colder to hotter. If heat were to leave the colder object and pass to the hotter one, energy could still be conserved.

How is carbon cycled through the biotic and abiotic components of an ecosystem?

Carbon cycles quickly between organisms and the atmosphere. Cellular respiration by living things releases carbon into the atmosphere as carbon dioxide. Photosynthesis by producers such as plants removes carbon dioxide from the atmosphere and uses it to make organic carbon compounds.

How does carbon move through biotic and abiotic sources?

Carbon moves through ecosystems in two cycles that overlap. In the biotic cycle, it moves between living things and the air. In the abiotic cycle, it moves between the air, ground, and oceans. By burning fossil fuels, humans have increased the amount of carbon dioxide in the air.

Which of the following protists is a type of algae that uses energy from the sun to make food?

Euglena These organisms, examples of Euglena, are protists that can feed like an animal or use the energy of the sun to make food like a plant.

How acidic is Yellowstone hot springs?

6.7-9.5 The take-home lesson is that reaction with rocks in the subsurface exerts a powerful control on the pH of the fluids, creating the alkaline-chloride fluids we commonly encounter in Yellowstone geysers and hot springs, which have pH values generally from 6.7-9.5.

How do humans affect biogeochemical cycles?

Recently, people have been causing these biogeochemical cycles to change. When we cut down forests, make more factories, and drive more cars that burn fossil fuels, the way that carbon and nitrogen move around the Earth changes. These changes add more greenhouse gases in our atmosphere and this causes climate change.

Why do we humans have a very big role in all the biogeochemical cycle?

Human-Induced Changes Fossil fuel burning, land-cover change, cement production, and the extraction and production of fertilizer to support agriculture are major causes of these increases.

How does the human body obey the laws of thermodynamics?

Heat transfer and doing work take internal energy out of the body, and food puts it back. If you eat just the right amount of food, then your average internal energy remains constant. Whatever you lose to heat transfer and doing work is replaced by food, so that, in the long run, ΔU=0.

How is thermodynamics related to human processes?

From the last few decades, classical thermodynamics is used to develop a fundamental understanding of the biological systems. The exchange of mass, momentum, and energy are all obeyed by natural methods. The second law of thermodynamics is essential to understand the phenomena of evolution, growth, ageing, and death.

What examples of everyday life might you have observed that provide evidence for the second or third law of thermodynamics?

These laws are observed regularly every day.

  • Melting Ice Cube. Every day, ice needs to be maintained at a temperature below the freezing point of water to remain solid. …
  • Sweating in a Crowded Room. The human body obeys the laws of thermodynamics. …
  • Taking a Bath. …
  • Flipping a Light Switch.

What is a real life example of the third law of thermodynamics?

Third Law of Thermodynamics Example Steam/vapours of water are the gaseous forms of water at high temperatures. The molecules within the steam move randomly.

What is biogeochemical cycle describe the details of nitrogen cycle and write its significance?

Nitrogen Cycle is a biogeochemical process through which nitrogen is converted into many forms, consecutively passing from the atmosphere to the soil to organism and back into the atmosphere. It involves several processes such as nitrogen fixation, nitrification, denitrification, decay and putrefaction.

What is the human impact on the carbon cycle?

Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere.

How is oxygen carbon dioxide cycle related to the process of photosynthesis and cellular respiration?

Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

How does phosphorus move through the biotic and abiotic parts of an ecosystem?

Phosphorous, also in the form of phosphate, may be transported by water or wind (both abiotic). Phosphorus is taken up by plants which are living and these plants may be consumed by other living organisms or they may die and be decomposed by decomposers, which are also living.

How do protists obtain energy and nutrients and what are the important roles protists play in the environment?

These protists are called filter feeders. They acquire nutrients by constantly whipping their tails, called flagellum, back and forth. The whipping of the flagellum creates a current that brings food into the protist. Other animal-like protists must "swallow" their food through a process called endocytosis.

Which statement describes how humans are affecting the balance of carbon in the atmosphere?

Which statement describes how humans are affecting the balance of carbon dioxide in the atmosphere? Fewer ag. crops are planted, reducing the amount of carbon dioxide released in to the atmosphere. Burning fossil fuels in great quantities has increased the amount of carbon dioxide in the atmosphere.

Are there acid pools in Montana?

Yellowstone National Park located in the states of Wyoming, Montana, and Idaho is known for its great wildlife diversity as well as its unique geothermal features. One of the most prominent and interesting sites within the park are the acid pools.

What is a thermal pool?

What is a thermal pool? A thermal (hot) pool or spring forms when rainwater seeps down through rocks to the earth's hot zone, where it gets heated. Then it bubbles up to form a pool, containing minerals dissolved from the rocks. Sitting in the water helps some people with medical problems.

Why do ecosystems matter for human health?

Why do ecosystems matter to human health? In a very fundamental sense, ecosystems are the planet's life-support systems – for the human spe- cies and for all other forms of life. The needs of human biology for food, water, clean air, shelter and relative climatic constancy are basic and un- alterable.

How does the environment human interaction contribute to cycles of essential molecules on Earth?

Human activities have greatly increased carbon dioxide levels in the atmosphere and nitrogen levels in the biosphere. Altered biogeochemical cycles combined with climate change increase the vulnerability of biodiversity, food security, human health, and water quality to a changing climate.

What impact do humans have on biogeochemical cycles explain?

Recently, people have been causing these biogeochemical cycles to change. When we cut down forests, make more factories, and drive more cars that burn fossil fuels, the way that carbon and nitrogen move around the Earth changes. These changes add more greenhouse gases in our atmosphere and this causes climate change.

How are humans a part of the biogeochemical cycle?

Human activities have mobilized Earth elements and accelerated their cycles – for example, more than doubling the amount of reactive nitrogen that has been added to the biosphere since pre-industrial times.

How does the first law of thermodynamics relate to the human body?

(a) The first law of thermodynamics applied to metabolism. Heat transferred out of the body (Q) and work done by the body (W) remove internal energy, while food intake replaces it. (Food intake may be considered as work done on the body.)

What implications does the first law of thermodynamics have for our energy usage How is the second law of thermodynamics relevant to our use of energy?

The first law of thermodynamics states that energy is conserved even when its form is changed, as for instance from mechanical energy to heat. By contrast, the second law of thermodynamics allows us to know how well an energy system performs in terms of the quality of the energy.
