Explanation: All plants and animals release at least some amount of co2 into the atmosphere during cellular respiration
Both plants and animals release carbon dioxide into the atmosphere during cellular respiration can be determined based on the Carbon cycle model. So, the correct option is B.
What is Carbon cycle?The exchange and recycling of carbon in the Earth's biosphere, lithosphere, hydrosphere and atmosphere is known as the carbon cycle. All living things contain the element carbon, which is also an important component of many important compounds such as proteins, lipids, and carbohydrates.
Photosynthesis, respiration, combustion and weathering are just a few of the different processes that make up the carbon cycle. Plants use photosynthesis to take up atmospheric carbon dioxide and convert it into organic molecules. Plants and other organisms then use these molecules as a source of energy.
Therefore, the correct option is B.

An important example of a "positive feedback loop" in the polar climate system is:
a.Scientists in remote places check on each others instruments.
b.Warming ocean water opens new areas for marine species.
c.Warmer winters cause more plant growth, providing more food.
d.Sea ice melt opens more ocean to sunlight, causing more melt.
Answer: D
Explanation:
A positive feedback loop occurs in nature when the product of a reaction leads to an increase in that reaction.
In choice D melting of sea ice opens more ocean to sunlight which causes more ice to melt which demonstrated a positive feedback loop.
The significant example of a positive feedback loop in the climate system i.e. polar should be at the time when the ice of the sea should be melt that there should be more ocean that results in more melting.
The following information related to the positive feedback loop is:
If the direction varies so it should result in an extra change in a similar direction.Like if we take an example that if there is an increase in the substance concentration so it results in the feedback that generated the continued increase in the concentration.Therefore we can conclude that option d is correct.
All other options seem incorrect.

What are some ways that the nitrogen cycle overlaps with or influences the oxygen and carbon cycles?
Are any of these interactions between the cycles positive?
Are any negative?
What about when the nitrogen cycle is thrown off balance by the Haber-Bosch process and others like it?
How can that influence the oxygen and carbon cycles?
Are there other cycles involved that have not been mentioned in this question?
What does this discussion suggest about the nature of the Earth as one large system?
Answer:
1. Nitrification occurs when soil microbes convert ammonium into nitrate. Much of the overlap between the carbon cycle and the nitrogen cycle occurs in the soil, in processes conducted by soil microbes. Microbes break down nutrients, build new compounds for their own growth, and eventually die.
The second question im not sure sorry- the positive and negative one ;(
3. Many human activities have a significant impact on the nitrogen cycle. Burning fossil fuels, application of nitrogen-based fertilizers, and other activities can dramatically increase the amount of biologically available nitrogen in an ecosystem. As nitrogen makes up 78% of the atmosphere, there is no shortage of it – it just isn't in a form plants and animals can use.
4. Carbon makes its way through living things as carbon-based compounds, like energy molecules, fats and proteins, eventually cycling its way back into the atmosphere. Nitrogen is mainly found in the atmosphere as well and enters the ecosystems as nutrients for plants. Water, nitrogen and carbon cycles. Carbon moves from the atmosphere and back via animals and plants. Nitrogen moves from the atmosphere and back via organisms. Water moves on, above, or below the surface of the Earth.
5. Carbon cycle, Nitrogen cycle, Nutrient cycle, Oxygen cycle, Phosphorus cycle, Sulfur cycle, Rock cycle, Water cycle.
6. Wind, water, and ice erode and shape the land. Volcanic activity and earthquakes alter the landscape in a dramatic and often violent manner. And on a much longer timescale, the movement of earth's plates slowly reconfigures oceans and continents. Each one of these processes plays a role in the Arctic and Antarctica.
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. Earth's surface is the only habitat available to the human race. Understanding the processes by which that habitat has been created and continually altered is important to determine the causes of environmental degradation.

how has paraquat stopped the algae from making atp nadph and sugars
Answer:
This is by disrupting the mechanisms of photosynthesis.Paraquat is an herbicide. A photosynthesis inhibiting herbicides. In the light dependent reaction, It acts as oxidizing agent by accepting electrons from Photo system I. and lose these electrons to oxygen molecules which becomes oxidized.
Therefore, disrupting the electron transport chain.With the electron transport chain disrupted, PMF is inhibited, electrochemical gradients for generating energy for ATPs synthesis, by ATPase synthase enzyme is blocked.
Therefore, ATPs synthesis is prevented. With this, Calvin Cycle is blocked, so no CHO id formed. With lack of electron transport chain, NADPH will not be formed. .

HOPE IT HELPS : D
Explanation:
Evolution is a very important phenomenon, which is the change in the characteristics of species of organisms over the course of life for the purpose of better survival.
What is evolution?The term “evolution” is best described as the process of gradual and continuous change in the inherited characteristics of a species over many generations.
This change is driven by mechanisms such as natural selection, mutation, and genetic drift, which lead to variation in traits within a population over time.
The theory of evolution by natural selection is widely accepted among scientists as the best explanation for the diversity of life on Earth. In addition to its importance in understanding the development of life on Earth, the concept of evolution has far-reaching implications for many areas of study, including medicine, agriculture, and conservation biology.

how to ecosystem services affect human sustainability
Answer:
Ecosystem services play important role in human sustainability. Ecosystem services include provisioning,regulating, supporting, and cultural.
Provisioning include production of food and water which is one of the essential requirement for human survival and provided by ecosystem in the form of plants or other animals. No food means no human life.
Regulating may include the control of disease and climate.Humans at different regions are susceptible to particular temperature and diversity in Climate provide required atmospheric condition for human survival. Climatic changes causes global warming which bring many diseases and temperature fluctuations that affect human sustainability. Diseases decreases human population and affect human susceptibility so ecosystem controls the diseases that increases chance of human survival. More diseases with no medicine may result into high mortality rate.
Supporting, such as oxygen production and nutrient cycles are important factors that support human sustainability because nutrients provide energy to humans to do work and oxygen is must for their living.
Cultural involve recreational and spiritual benefits. Recreational and spiritual benefits include regulation of physical and mental health and social interaction with other people that keeps a human healthy and happy for living a good life.
Hence, ecosystem services promote and affect human sustainability.

Explain the unique bonding properties of carbon.
Carbon , hence overcomes this difficulty by sharing its four valance electrons with other atoms of carbon or with atoms of other elements.
What do you mean by valence electrons?A valence electron is an electron in the outer shell associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed.
Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell.
For neutral atoms, the number of valence electrons is equal to the atom's main group number. The main group number for an element can be found from its column on the periodic table.
