Photosynthesis is a means of converting light energy to chemical energy. Explain what this statement means.
Answers
Answer:
photosynthesis, the process by which green plants and certain
other organisms transform light energy into chemical energy .
During photosynthesis in green plants, light energy is captured
and used to convert water, carbon dioxide, and minerals into
oxygen and energy-rich organic compounds.
also
During the process of photosynthesis, light penetrates the
cell and passes into the chloroplast. The light energy is
intercepted by chlorophyll molecules on the granal stacks.
Some of the light energy is converted to chemical energy.
During this process, a phosphate is added to a molecule to
cause the formation of ATP(Adenosine triphosphate)
Let's take a short look at photosynthesis before moving on to this topic.
It is an exergonic, light-dependent, biological, oxidoreductive, energy-yielding process. Where sugars or (CH2O)n are produced energetically by reducing CO2.
Although Co2 is essentially prevalent in nature, it does not break down into sugars since the reaction is thermodynamically possible.
Right after sunlight strikes the surface of the leaf, there are these little components known as reaction centers or energy harvesting cores, which are surrounded by antenna complexes. These antenna complexes are normally composed of chl a, chl b, xanthophyll, carotenoid, etc.
Here, the antenna complexes serve as filters, allowing just the necessary amount of flux to depart the outershelled electron of the chlorophyll molecule via energy activation states (of different kinds).
As the pigment system activates the chlorophyll molecule, the energy from the light is now transferred to chemo potential energy, which is subsequently employed in the process to oxidize the water molecule by the Kok clock mechanism.
Now this is an rather interesting cycle having multiple energy states, from Ground (SO) to maximum (S4) notice that the energy was first required to move on to next step in intermediates but as soon as it reached S4 or max state it oxidized water and this energy is actually enough to reduce Carbon di Oxide to sugar.
(Attachment #1)
If I'm not incorrect, the conversion works like this.
(Attachment #2)
As a result, it needs to be activated gradually in order to build up enough energy to pass the energy barrier.
NOTE:
As you can see, plants don't purposefully create oxygen, but why do they continue to do so? It does this because its primary goal is to turn sugar into oxygen, which it then converts into water that actually vaporizes while keeping the system cool.

Think about challenges related to marine science which are currently facing society. In coastal and inland communities alike, there might be challenges such as pollution, invasive species, or waste management. Communities also face public health issues, such as outbreaks of diseases, and ethical concerns surrounding science and technology. Communities turn to fellow citizens, scientists, engineers, and other professionals to solve these problems. Many times these problems are not clearly defined or easy to solve. They involve many variables and points of view. Your task is to analyze a global challenge related to marine science, and to specify qualitative and quantitative criteria and constraints for solutions that account for societal needs and wants.
Answers
Global challenges related to marine science are as follows:
1. Ocean acidification is a major issue that affects all of the world's ocean industries and has severe negative effects on the environment, society, and the economy. Coordinated government action is required to effectively address this issue.
What is impact of ocean acidification?Ocean acidification will affect the biological, biogeochemical, and ecological aspects of the oceans, and while the effects on the environment, the socio-ecological system, and human dimensions are all still not fully understood, they have the potential to have very dramatic effects. Numerous marine ecosystem services and goods may be impacted directly or indirectly. Industries that rely on these services from the Ocean are impacted.
2. Overfishing:
Overfishing poses a severe threat to the fish in our water, whether it's for the food industry or the aquarium sector. The Food and Agriculture Organization estimates that more than half of the species of marine fish have been totally or overexploited, despite the fact that many of them simply need to remain in the sea because they are not necessary for food security or because they cannot survive in captivity. We are killing entire ecosystems and the food chains that are necessary to keep them healthy by overfishing. Overfishing not only causes the extinction of entire species, but it also directly affects other species in the food chain.
3. Plastic
Between 1.15 and 2.41 million tons of plastic enter the ocean every single year. The Great Pacific Garbage Patch, which is a collection of rubbish in the Pacific Ocean is now three times the size of France. Animals can get tangled in the huge amount of plastic which litter the ocean, and the plastic smothers and destroys coral and sponges. Plastic bags are also often mistaken for food by sea turtles, and they either become trapped or eat the bag which clogs their digestive system. Plastic continuously breaks down resulting in little pieces of “micro-plastic” that are consumed by a variety of marine life, including several species that humans like to catch and eat.
solutions that account for societal needs and wants:
1. Cutting back on carbon emissions.
2. Reducing plastic usage.
3. Making sure the fish you consume is supplied sustainably and ethically.
4. Participating in beach cleanups.
5. Only purchase aquarium fish that were raised in captivity.
6. Supporting elected officials that favor a wholesome atmosphere

Explanation:
Density independent is the factor that will affect a population no matter its size. Temperature, natural disasters, and oxygen levels all influence this.
The correct term to describe the type of limiting factor that causes the destruction of both the small population of trees and the large population of birds in this scenario is "density-independent." Density-independent factors are environmental factors or events that affect populations regardless of their size or density.
What is density-independent?Density-independent factors are environmental factors or events that affect populations regardless of their size or density. These factors exert their influence on population dynamics independently of population density. Density-independent factors include natural disasters like earthquakes, floods, hurricanes, and forest fires, as well as extreme weather events, habitat destruction, pollution, and certain diseases.
In this case, the forest fire is an example of a density-independent factor because it can impact both the tree population and bird population regardless of their respective sizes or densities.

The word in their names shows that two of the plants share the greatest number of features is marsh. Therefore, option A is correct.
What is marsh ?A marsh is a type of wetland where herbaceous plant species, not woody ones, predominate. The transition between the aquatic and terrestrial ecosystems is commonly formed by marshes, which are frequently found along the borders of lakes and streams. Grass, rush, or reeds frequently rule over them.
Cattails, sedges, papyrus, and sawgrass are typical examples. Most aquatic creatures, including fish and salamanders, can survive in water with little oxygen.
In a marsh, herbaceous plants make up more than half of the vegetation, and the pH of the soil is neutral. There are fewer than 30% woody plants in the area. Throughout the growth season, a marsh has standing water for extended periods of time.
