(Environmental) Southern England What are the major concerns about soil erosion on arable land in Britain?
Answer:
Soil nutrient loss
Algae blooms
Pollution of water ways
Explanation:
Soil nutrient loss - a major concern as when soil erodes, this results in nutrient run off. Heavy rains can "wash away" essential nutrients within the soil therefore reducing the fertility of the land.
Algae blooms - when nutrients run off soil as a result of soil erosion they can leech into nearby fresh stream and even into salt water marine environments. This large increase of nutrients results in algae thriving and forming a layer across the top of the water. This reduces the oxygen and sunlight available to other marine plants and essentially suffocates plant and animal species.
Pollution of water ways - The sediment of soil that is eroded makes its way into fresh water ways can not only "bury" plant species and reduce biodiversity but it also reduces the water quality. It can introduce pathogens to the water from liverstock farming as well as introducing pesticides that may be harmful to wildlife.

Suppose we completely stopped burning fossil fuels immediately. How many years would it take to return to atmospheric CO2 levels from the year 1800, about 600 GtC? Use the Gizmo to find the answer.
Answer:
Explanation:
It would take 50 years to return to atmospheric CO2 levels from the year 1800. I know this because I set the fossil fuel usage to 0 and proceeded to simulate 50 years and that’s when the atmospheric CO2 levels returned to 600 GtC.
As per observation It could take 50 years to go back to atmospheric CO2 degrees from the yr 1800.
Each year, there has been no extrade in the quantity of CO2 withinside the ecosystem because of soil and land plants. coal also can be the answer.
What is co2 quantity ?Since 2000, the worldwide atmospheric carbon dioxide quantity has grown with the aid of using 43.5ppm, an growth of 12 percent. The contemporary-day document of atmospheric carbon dioxide degrees commenced with observations recorded at Mauna Loa Observatory in Hawaii.
Thus it is well explained.

1)What is a trophic level?
2) explain how energy travels through food web ? your response must include the following terms:
Decomposer,producer, primary, consumer , 10%.
3)why is energy reduced at successive trophic levels?
1. The trophic level is something's position in the food chain/food web.
2. Energy travels through out the food chain because all the animals eat each other and take each other's energy. The decomposers are eaten, the producers are eaten, but the primary consumers get all the energy.
3. The energy decreases because each animal decomposes the energy a little, before getting eaten. By the time the food reaches the top of the web, the energy is barely left.

Brown-headed cowbirds sometimes lay eggs in warblers' nests, killing the warblers eggs. Blue jays are known predators of the golden-cheeked warblers' offspring. The survival of golden-cheeked warblers would be most threatened by an increase in the —
Answer:
C. clearing of ash juniper trees for farmland
Explanation:
Golden-cheeked warblers will be in more danger if "clearing of ash juniper trees for farmland" will increase because juniper trees provide barks to build the nest for Golden-cheeked warblers, if Golden-cheeked warblers will not get enough barks to build the nest, they will not able to reproduce and their population will decrease further.

Which surface erosion event does the most short- term damage?
Loss of topsoil from farmland.
Movement of rocks by glaciers.
Occurrence of mud slides after heavy rains.
Pollution of water sources caused by runoff.
Answer:
Occurrence of mud slides after heavy rains.
Explanation:
Soil erosion is defined as the removal of top soil from the land and it affects the fertility of the soil. It is also known as soil degradation.
Soil erosion has both short-term and long-term damage. Short-term damage of erosion includes the occurrence of mudslides after heavy rains which is called landslide. It is a short-term damage because landslides took long-duration to happen and when happened it can be shortly recovered using machines.
Hence, the correct answer is "the Occurrence of mudslides after heavy rains."

The chemical reaction equation of photosyntesis is shown here:
6CO2 + 6H2O → C6H12O6
What information is not given in this equation.
A)It does not show if the reaction is reversible or not reversible.
B)It does not show the reactants needed for the reaction.
C)It does not show that photosynthesis consists of many separate steps.
D)It does not show the number of molecules required to produce glucose.
Answer:
C
Explanation:
C appears to be the best answer but I think a better answer would be that it didn't include another product which is oxygen. So unless it is late and my brain is not function, I would say that should be the answer. But otherwise, since it is not there, C is the best one I think.
The chemical reaction equation of photosynthesis is shown here:
6CO2 + 6H2O → C6H12O6, C)It does not show that photosynthesis consists of many separate steps. Thus option "C" is correct.
What is photosynthesis?
The chemical reaction of photosynthesis is given as follows;
6CO₂(g) + 6H₂O(l) + Energy from light → C₆H₁₂O₆(s) + 6O₂(g)
Therefore, six molecules of gaseous carbon dioxide (CO₂) combine with six molecules of liquid water (H₂O) in the presence of energy from Sunlight to produce one molecule of solid glucose (C₆H₁₂O₆) and six molecules of gaseous oxygen (O₂)
The 6O₂ is the gaseous oxygen produced as a byproduct of photosynthesis

Explanation:
Explain the importance
of decomposers to the overall
biogeochemical cycle.
Answer: Decomposers plan an important role in the biogeochemical cycling for nutrients in the environment as they are responsible for the breakdown and return of nutrients back to the environment in their native state.
Decomposers are essential for the biogeochemical cycle as they facilitate the recycling of nutrients, provide energy for other organisms, and help maintain the health and balance of ecosystems by Breaking down organic matter, Recycling nutrients, Energy flow and Detoxification.
Without decomposers, organic matter would accumulate, nutrients would become locked up, and energy flow within ecosystems would be disrupted.
Decomposers play a crucial role in the overall biogeochemical cycle. Here's why they are important:
Breaking down organic matter: Decomposers, such as bacteria and fungi, break down dead plants, animals, and other organic materials into simpler compounds. They do this through the process of decomposition, where they release enzymes that break down complex molecules into smaller, more manageable forms.
Recycling nutrients: By decomposing organic matter, decomposers release essential nutrients back into the ecosystem. These nutrients, such as carbon, nitrogen, phosphorus, and sulfur, are then made available for uptake by plants and other organisms. This recycling of nutrients is vital for maintaining the balance and productivity of ecosystems.
Energy flow: Decomposers also play a crucial role in energy flow within ecosystems. When they break down organic matter, they release energy in the form of heat. This energy can then be used by other organisms in the ecosystem, such as primary consumers (herbivores) and secondary consumers (carnivores), to carry out their life processes.
Detoxification: Decomposers are capable of breaking down and detoxifying harmful substances and pollutants in the environment. For example, certain bacteria can break down pesticides and other chemical pollutants, helping to reduce their negative impact on the ecosystem.
