O A government sells a section of prairie to a private company interested in drilling for oil.
A rancher cuts down several trees on her property to get wood to use to repair a fence.
A national forest suffers from erosion due to the use of all-terrain vehicles.
Answer:
Likely the government selling off the prairie
Explanation:
Everyone is losing out on the prairie getting sold to a private corporation, hence why this is the tragedy of the commons
The scenario in which the land is most likely to be degraded as a result of the "tragedy of the commons" is a national forest that suffers from erosion due to the use of all-terrain vehicles. Thus, the correct option for this question is D.
What is land degradation?Land degradation may be defined as the process through which the value of the biophysical environment is affected by a combination of human-induced processes acting upon the land. All these influences gradually reduce or lose the biological or economic productivity and complexity of rain.
A national forest that suffers from erosion due to the corresponding utilization of all-terrain vehicles ruptures the soil productivity due to erosion. This finally leads to the degradation of land with respect to the "tragedy of the commons".
Therefore, the correct option for this question is D.

Explanation:
Molecular systematics might examine all of the following types of data except anatomical features.
The model shows the flow of energy at each trophic level.
Which trophic level contains the most energy, and why?
A Producers; they have the largest number of individuals of all the trophic levels.
A Producers; they have the largest number of individuals of all the trophic levels
B Primary consumers; they have the most variety of plants from which to obtain energy.
C Secondary consumers; they release the least amount of energy into the next trophic level.
D Tertiary consumers; they have the smallest number of individuals that need to collect energy.
Answer:
The correct answer is A.
Explanation:
Producers are photosynthetic organisms such as plants and algae. They absorb energy from the sun and convert it to food. This group includes the largest number of individuals. Each of the higher trophic levels includes fewer individuals than the level below it, and roughtly 90% of the energy consumed by each level is lost as heat, meaning that the amount of energy at the highest trophic level is only a fraction of the energy found at the producer level.

Describe how a decrease in ocean ph can affect marine organisms.
Ocean acidification can negatively affect marine life, causing organisms shells and skeletons made from calcium carbonate to dissolve. The more acidic the ocean is, the faster the shells dissolve.
Hope this helps :))
Organisms depend on pH for living in aquatic life, because due to acidification carbonate is lost, which is the main basic ingredient of saltwater.
How ocean pH affects marine organisms?Carbonate, a main basic ingredient of salt water, is lost as a result of ocean acidification. This makes it more challenging for marine organisms to develop shells and skeletons.
Ocean acidification is sometimes called to as "sea osteoporosis" with a great cause. Ocean acidification can dissolve the minerals used by oysters, clams, lobsters, shrimp, coral reefs, and other sea animals to create their shells and skeletons.
Human health is also an issue, when the acidity of the water increases, the mucus on fish gills hardens, limiting the quantity of oxygen that may enter. This is why pH changes regularly result in fish deaths.
Therefore loss of carbonate from the ocean, the pH of the ocean affects the marine organisms.

What will happen you happen if you apply jelly on the leaves of a plant how will photosynthesis work
Answer:
I feel it will no longer be healthy because the jelly applied to the leaves blocked the stomata. As a result, the plant would be deprived of oxygen needed for respiration. It wouldn't be able to carry out photosynthesis since it wouldn't have access to carbon dioxide.
Another Answer could be:
When you apply the jelly to the stomata of the leaves, they become covered, and transpiration ceases. This reduces the escape of water vapour and allows the leaf's moisture to be retained for a longer period of time. However, because the jelly layer prevents all sorts of gaseous exchange, photosynthesis and respiration are also impossible.

How does the law of conservation of mass apply to earth’s recycling of water, oxygen, carbon, and nitrogen. Give one example
Answer:
The law of conservation of mass states no matter is created or destroyed. This means that the matter currently on Earth is the only matter that will ever be available to us. However, it also means that this matter will not be destroyed. So, water, oxygen, carbon, and nitrogen are all used by living things in our world and then recycled to be used again.
One example of this is the water cycle. More water is never added or taken from the world, it is just reused. First, water starts in some body of water and then evaporates into the air. Then, the water falls back to Earth as precipitation.
