Why is phosphorus a limiting growth factor in terrestrial ecosystems?
Answer:
Because the quantities of phosphorus in soil are generally small, it is often the limiting factor for plant growth. ... Phosphates are also limiting factors for plant-growth in marine ecosystems, because they are not very water-soluble. Animals absorb phosphates by eating plants or plant-eating animals.
have a good day
#BRAINLESTPhosphorus is a limiting growth factor in terrestrial ecosystems because the quantity of phosphorus in soil are generally small it is often the limiting factor for plant growth.
What is the use of phosphorus in ecosystem?Phosphorus-based fertilizers boost the growth of plants on land, phosphorus in the ocean increase the production of microbes and small marine plants called phytoplankton, which compose the base of the marine food chain.
Phosphorus, like nitrogen, is a critical nutrient required for all life. The most common form of phosphorus used by biological organisms is phosphate (PO4), which plays major roles in the formation of DNA, cellular energy, and cell membranes (and plant cell walls). Phosphorus is a common component in commercial fertilizers.
We can say that phosphorus are very important factor for plant-growth in marine ecosystems because they are not soluble in water.
Therefore, Phosphorus is a limiting growth factor in terrestrial ecosystems because the quantity of phosphorus in soil are generally small it is often the limiting factor for plant growth.

Which label belongs in the region marked X?
involves changes in temperature
has a constant volume
shows an inversely proportional relationship
does not describe pressure changes
Answer:
Shows an inversely proportional relationship.
Explanation:
The Boyle's law belongs in the region marked X whereas the other circle belongs to Charles law. There is inverse relationship between the two circles or these two laws because in Boyle's law, temperature is constant while on the other hand, in Charles law pressure is constant instead of temperature. In Boyle's law, pressure of a gas is inversely with its volume whereas in Charles law, the volume of a gas is directly proportional to its absolute (Kelvin) temperature.

1.DNA is a molecule composed of two chains in form a ____________ compose by______________, ____________ and pentose. And the structure and function of genes.
Answer:
DNA is a molecule composed of two chains in form of a DOUBLE HELIX compose by ORGANIC NITROGEN CONTAINING BASE, PHOSPHATE GROUPS and PENTOSE.
Explanation:
Nucleic acids are found in all living cells. They are composed of strands made up of repeating units called nucleotides. Each nucleotide consists of
--> a five carbon sugar( PENTOSE)
--> a phosphate group
--> an organic nitrogen containing base: adenine, guanine, cytosine or thymine.
The two types of nucleic acids include:
--> Deoxyribonucleic acid ( DNA) and
--> Ribonucleic acid ( RNA)
Deoxyribonucleic acid ( DNA) is found in chromosomes located in the nucleus of cells.
STRUCTURE OF DNA
The DNA molecule consists of two strands that curve spirally to form a double helix structure. The strands are held together by hydrogen bonds between the base side arms. Each base on one strand will only pair with a specific base on the other strand: hence guanine will only pair with cytosine and adenine with thymine.
FUNCTIONS OF DNA
It stores the organism's hereditary traits and directs the day to day metabolic activities of each cell in the organism.

What is ecological succession?
A. Change that happens over time in an ecological community
B. A way a life
C. One person giving another person power
Answer:
A. Change that happens over time in an ecological community
Explanation:
Ecological succession is the change that happens over time in an ecological community. So, option (A) is the answer.
Answer:
A. Change that happens over time in an ecological community
Explanation:
Ecological succession is the gradual process by which ecosystems change and develop over time. Nothing remains the same and habitats are constantly changing.
There are two main types of succession, primary and secondary.
Primary succession is the series of community changes which occur on an entirely new habitat which has never been colonized before. For example, a newly quarried rock face or sand dunes.
Secondary succession is the series of community changes which take place on a previously colonized, but disturbed or damaged habitat. For example, after felling trees in a woodland, land clearance or a fire.
What does the theory of evolution tell us about living things?
A) The environment can make them change rapidly over a short period of time. B)They create fossils when they die
C)Their environment makes them change slowly over time.
D)They can give us clues about extinct species. (science 7th grade) (100 POINTS)
Answer:
Their environment makes them change slowly over time
Explanation: I took the test and got it correct.
The agents of wethering erosion deposition and the rock cycle will slowly change the fossils over time. They may damage them or burry them deep into the layers of earth. Over time, as they age, new landforms will me made ontop of them. This is why they use the fossils to determine the age of the land. I hope this helps :)
