which abiotic factor starts the phosphorus cycle?
Answer:
Phosphorus moves in a cycle through rocks, water, soil and sediments and organisms. Over time, rain and weathering cause rocks to release phosphate ions and other minerals. This inorganic phosphate is then distributed in soils and water.
why is there no enzyme to digest vitamins
Answer:
Vitamins are used in their original form by the cells. They are either water soluble or fat soluble, hence no enzyme is required to digest vitamins. They are absorbed directly from the digestive tract, transported by blood to the cells, and the cells absorb and use them whenever they need.

Identify two specific populations that most likely increased in number after the mountain lion population decreased. Explain why.
Any change that occurs at any link of a trophic web will affect the other links. The two specific populations that most likely increased in number after the mountain lion population decreased are rabbits and deers.
----------------------------
The trophic web is a relationship process between different organisms, through which occurs transference of energy. The ones placed at lower levels pass energy to the ones at the higher levels.
Organisms at each level feed on the preceding one and become food for the next one.
The first link corresponds to a producer organism -autotroph-.The following links are the consumers -heterotrophs-: herbivores and carnivores. The last links are the decomposers that degrade organic matter from dead organisms.
As it is a web, all organisms are equilibrated until a change occurs.
When the change affects any of the involved links, there can be a cascade effect on the web.
A change in a link population size (increasing or decreasing) will affect the superior links and the immediately anterior link.
Also, when two or more species are competing for the same source of food, a change in any of the population sizes will affect the other ones.
According to the provided trophic web, puma feeds on deer and rabbit.
Since puma was killed, their population size sharply decreased.
This fact followed the predator-prey cycle, in which the predator regulates the prey population size and vice-versa. When there is a decrease in the predator population size, the prey population increases in size because of the absence of their natural predators.
In the absence of puma, deer and rabbits increase their population size. They live in an environment with no predators and enough resources.
The number of individuals of each species increased, and the amount of food consumed increased too.
This change negatively affected grasses and grains, which were over-consumed. Also, crickets and mice were affected too because they compete for the same food source.
So, cascade effects would be as follows,
1) The decreased in the puma population size caused an increase in the deer and rabbit population size.
2) The increase in the deer and rabbit population size caused a decrease in the grains and grasses species population, because they were over consumed.
3) The decrease in grains and grasses caused a decrease in the cricket and mouse population, because they feed on the first ones, competing with deer and rabbits for food.
The two specific populations that most likely increased in number after the mountain lion population decreased are rabbits and deers.

Answer: 60 degrees the front is cold so it would be 60 degrees in Virginia the next day
ExplanationExplanation:
Based on the consistant pressure that the front seems to be causing, temperatures will become cooler. Based on the four choices provided, only one makes the temperature cooler which is A.
This front seems to be making its appearance during the overnight hours, therefore causing colder temperatures the morning following. With temperatures being 68 degrees at the time, the external temperature will be cooler than 68 degrees.

In deserts there’s a strong environmental pressure to conserve water. How did cactuses evolve to meet this pressure?
Answer:
Cacti evolved in the way that they are able to hold watter within themselves and their cells.
Explanation:
Cactuses have evolved in such a way that their roots and leaves hold water as long as possible. This gives the capability of cacti to meet this environmental pressure in order to conserve water.
What are the special adaptations of the cactus?Under desert climates, cacti have various numerous unique adaptations in order to facilitate their survival in the same habitat. It includes its roots, leaves as well as stems that enable it to thrive in desert environments.
These adaptations include: Leaves are reduced to spines to reduce water loss through transpiration. Wide and deep roots absorb rainwater on the surface and reach the underground deep water.
Therefore, cactuses have evolved in such a way that their roots and leaves hold water as long as possible.

Which of these other features in the landscape could be the reason for the high levels of phosphorus? many cars cow pasture solar panels forest.
Algae blooms are caused by an oversupply of nutrients like to water bodies, causing eutrophication. In the exposed example, a reason for the high levels of phosphorus is option B. Cow pastures.
-------------------------
Eutrophication is a biological process produced in water by an oversupply of nutrients or organic matter.
The source of these high nutrient levels, especially nitrogen and phosphorus, are anthropogenic activities.
This oversupply favors phytoplankton multiplication, especially cyanobacteria.
Cyanobacteria can grow in seawater, but blooms mainly occur in freshwater where the salinity level is low.
These algae species that affect freshwater bodies are microscopic, photosynthetic organisms.
Blooms of cyanobacteria reflect the sanity state of water and its abiotic characteristics. They cause severe disasters in water biota and affect human health.
This overgrowth leads to an enhance in primary productivity and reduces the pass of radiation to deeper strata. This fact affects biota in deeper zones.
Gradually sedimentation begins, caused by the death of some vegetable organisms that sink in the bottom.
These sediments suffer decomposition in the presence of oxygen.
When oxygen disappears, anaerobic bacteria act and produce fermentation.
Phytoplankton overgrowth on the surface and fermentation process in the bottom, originate toxic compounds that can damage the animals in the water body and humans that get in touch with this water.
Animals die, creating more sediments in the bottom where there are anaerobic conditions.
The lack of oxygen and light continued to increase in decomposition, and fermentation produces a bad smell and toxicity.
Concerning the sources of nutrients that might be causing these events, we can mention, among others, cow pasture.
Cow pasture increases the levels of phosphorous on the ground, which ends in water streams, and from there to ponds or lakes.
