God uses photosynthesis to provide for life all over the world by using energy from the sun to convert carbon dioxide and water into oxygen and glucose.

This process is called photosynthesis and it is how plants, algae, and some bacteria are able to produce their own food from sunlight. This food is then used to create energy for the plants, and when the plants die and decompose, the energy is released back into the atmosphere as carbon dioxide. This process provides the oxygen that all life on Earth needs to survive, and it also recycles carbon dioxide back into the atmosphere to be used again. The recycling of carbon dioxide is essential for maintaining the balance of oxygen and carbon dioxide in the atmosphere, which is necessary for life to exist on Earth.

The diagram depicts the main metabolic procedures involved in the biosphere's carbon flux. These include mineral oxidation, oxidative respiration (which produces ATP), light absorption, and glycolysis (which leads to carbon fixation).

Mineral oxidation involves the breakdown of inorganic compounds, such as iron or sulfur, releasing carbon dioxide (CO2) into the atmosphere. Oxidative respiration occurs when organic compounds, like glucose, are broken down in the presence of oxygen, producing CO2 as a waste product and ATP as an energy source. Light absorption by plants through photosynthesis converts CO2 into organic compounds, such as glucose, through carbon fixation. Glycolysis is the initial metabolic pathway in both aerobic and anaerobic respiration, converting glucose into pyruvate and ATP. Overall, these metabolic processes play important roles in the cycling of carbon in the biosphere.

The mobile electron carriers are ferry electrons between one respiratory complex and the next. So, the correct choice is option(d).

The electron transport chain (ETC), which functions in the mitochondrial membrane, consists of four protein complexes and two mobile electron carriers. Mobile electron carriers are small proteins or hydrophobic molecules that make up the respiratory chain. Electron carriers play a central role in many biological processes, including cellular respiration. During cellular respiration, electrons from glucose molecules are captured by electron carriers. After going through several steps, glucose is broken down and energy is gradually produced through the electron transport chain. Thus, a molecule can accept one electron from another molecule (electron donor) and in the process of electron transfer can carry electrons to donate to another molecule. NAD⁺ (Nicotinamide adenine dinucleotide) is an example of an electron carrier. So option (d) is the correct answer.

voluntary muscle control is conscious control of skeletal muscles, while involuntary muscle control is the automatic regulation of smooth muscles, cardiac muscles, and glands.

The human body has two types of muscle control: voluntary and involuntary. Voluntary muscle control refers to the ability to consciously control the movement of skeletal muscles, which are attached to the bones and responsible for locomotion and other bodily movements. Involuntary muscle control, on the other hand, refers to the automatic or reflexive control of smooth muscles, cardiac muscles, and glands.

Voluntary control of muscles is initiated by the central nervous system, which sends signals from the brain to the muscles through the motor neurons. This type of muscle control is under conscious control, meaning that the individual can decide when and how to move their muscles. Examples of voluntary muscle control include walking, talking, and typing on a keyboard.

Miosis is the opposite of mydriasis, which causes your eyes' black centres to enlarge dramatically. The size of the pupils is normally equal.

They narrow in reaction to direct illumination (direct response) and the opposite eye's illumination (consensual response). Darkness causes the pupil to enlarge. The pupil is constricted by the pupillary light reflex in reaction to light, and this is done by innervating the iris sphincter muscle. Myosis, also known as miosis, is the severe constriction of the pupil (from the Ancient Greek v (mein) "to close the eyes").

Mydriasis, the opposite ailment, causes the pupil to enlarge. In the body, dilatation and constriction are opposing but connected processes.

Passive transport occurs when substances move from a high concentration region to a low concentration area through a process known as diffusion.

A concentration gradient is a physical space in which the concentration of a particular substance varies. Active transport is the movement of molecules across a cell membrane in the opposite way of their concentration gradient, from low to high concentration.

Substances move against the concentration gradient during active transport, from a low concentration region to a high concentration area. This procedure is considered "active" because it necessitates the use of energy (usually in the form of ATP). It is the polar antithesis of passive transportation.

Explanation:

l hope you understand the answer

Aquatic ecosystems typically have an inverted biomass pyramid when compared to terrestrial ecosystems due to differences in the efficiency of energy transfer and nutrient cycling between the two systems.

In a terrestrial ecosystem, primary producers such as plants capture energy from the sun and convert it into organic matter through photosynthesis. This energy is then transferred to herbivores, which are in turn consumed by carnivores and other higher-level consumers. As a result, the biomass of each trophic level decreases as we move up the food chain, resulting in a pyramid-shaped biomass distribution.

in contrast, in aquatic ecosystems, primary production is often limited by nutrients rather than energy. This is because water can act as a barrier to the diffusion of nutrients, making them less available to organisms. As a result, primary producers in aquatic ecosystems tend to be small, fast-growing organisms such as phytoplankton, which are highly efficient at capturing and recycling nutrients. This high productivity can support a larger biomass of herbivores and other consumers, resulting in an inverted biomass pyramid.

Furthermore, in aquatic ecosystems, many organisms occupy multiple trophic levels simultaneously, such as fish that consume both herbivorous and carnivorous organisms. This can lead to overlapping trophic levels and a less distinct pyramid shape.

Overall, the inverted biomass pyramid in aquatic ecosystems reflects the unique ecological dynamics and nutrient cycling that occur in these environments, and highlights the importance of considering the specific characteristics of each ecosystem when studying ecological relationships.

Slow-growing forests can have a low net primary production (NPP) yet store a large amount of biomass because of their slow growth rate.  

This is due to the fact that slower-growing forests have a higher likelihood of accumulating biomass over a longer period of time since less biomass is lost to breakdown and other processes.

Although carbon is released into the atmosphere more slowly in slow-growing forests, there is a tendency for these forests to have larger carbon concentrations in their biomass.

Because of this, forests can store more biomass even when their rates of growth and photosynthesis are low.

As for their higher biomass and carbon storage, slow-growing forests also tend to be more resistant to disturbances like wildfires or insect infestations. As a result, despite having a low NPP, they may store a lot of biomass.

The feedback loops whether positive or negative are used to keep the systems at or near their setpoints.

While, the feedback loops are typically divided into two categories:

1) Positive feedback loops: As one thing changes, another thing also changes, and so on.

For instance, as a substance's concentration rises, a feedback loop results in further concentration rises.

2) Negative feedback loops, where a change in one direction results in a change in the other.

For instance, an increase in a substance's concentration can result in feedback, which eventually leads the substance's concentration to drop.

Most of the systems with positive feedback loops are by simply nature unstable. The Positive feedback loops can sometimes result in runaway conditions because a change in an input prompts responses that keep changing in the same direction.
