a) In a food chain, arrows show the movement of nutrients or energy from one organism to another. It refers to the direction of transfer of energy or nutrients from the organism being consumed to the organism consuming it.
b) The producer in the diagrammatic food chain is lettuce, followed by green fly, ladybug, thrush and cat. Producers—also called autotrophs—are living things that can make their own food through photosynthesis or chemosynthesis, the process by which sunlight or inorganic substances are converted into energy-rich organic molecules.
c. Ladybird is the third trophic level of the food chain. The term "trophic level" describes the place an organism occupies in a food chain or web, from where it obtains its food and energy. In this scenario the greenfly is the primary consumer at the second trophic level, while the ladybird is the secondary consumer at the third trophic level. Lettuce is the first trophic level in this scenario (producer).
d.Cat is the third largest consumer in the provided food chain. In a food chain or web, tertiary consumers are those species at the highest trophic level. Typically, they are carnivores that prey on other carnivores or secondary consumers.
e) Sun is the primary energy source that powers the food chain. Most ecosystems get their energy mostly from the sun. As the species consumes and is consumed by other organisms, it is passed along the food chain after being captured by producers (such as plants) through photosynthesis.

where is earth's magnetic north pole?
Answer:
The north magnetic pole is a point on the surface of Earth's Northern Hemisphere at which the planet's magnetic field points vertically downward (in other words, if a magnetic compass needle is allowed to rotate in three dimensions, it will point straight down)
Explanation:
There is only one location where this occurs, near (but distinct from) the geographic north pole. The geomagnetic north pole, a related point, is the pole of an ideal dipole model of the Earth's magnetic field that most closely fits the Earth's actual magnetic field.
The Earth's magnetic pole is situated at west of the Ellesmere Island in northern Canada at the geographical location of 81°18′N 110°48′W.
What is the Earth's magnetic pole?The generation of the Earth's magnetic field occurs deep within the Earth's interior, in a layer which is known as the outer core to be more precise. Here, the convective energy from the slow-moving molten iron is converted to the electrical and magnetic energies.
The north magnetic pole of the Earth moves over time according to the magnetic changes and flux lobe elongation in the Earth's outer core. In the year 2001, it was determined by the Geological Survey of Canada to lie west of the Ellesmere Island in northern Canada at the geographical location of 81°18′N 110°48′W. It was situated at 83°06′N 117°48′W in 2005.

Outline what has to occur in the body for a reflex and a voluntary action to occur.
Answer:
For involuntary actions (reflexes) the information is first detected in the sensor and travels along sensory neurons to the spinal cord. Once the action potential reaches the spinal cord, the information is transmitted across the synapse to the motor neuron. for voluntary actions,
movements are commanded by the motor cortex, the zone of the cerebrum located behind the frontal lobe. The motor cortex sends a neural message that moves through the brain stem along the spinal cord and into the neural network to the muscle being commanded.
how is cytokinesis different in plant and animal cells

Temperature is vital for successful beer and wine making.why is it so important ?
Temperature is vital for successful beer and wine making is it so important because in this process bacteria are very helpful and important factor and for them temperature must be minimized.
What is the role of bacteria in the formation of beer?In the formation of beer bacteria plays a vital role as they totally perform a function and due to this there is a change in the taste and concentration of the beer.Temperature is vital for successful beer and wine making is it so important because in this process bacteria are very helpful and important factor and for them temperature must be minimized.
The process by which wine has been prepared is known as fermentation and ethanol has a colourless liquid which catches fire easily and it has been produced by the process of the natural fermentation of the sugars or alcohol. Ethanol has been also known as the alcohol which has colourless and slightly toxic chemical compound and the ethanol forms water as well as carbon dioxide.
Therefore, Temperature is vital for successful beer and wine making is it so important because in this process bacteria are very helpful and important factor and for them temperature must be minimized.

The term that would best define the fish added to the pond is INTRODUCED species. These species may be harmful to native species.
Introduced species are exotic species which has arrived there by human activity, which may be harmful to native species.
Introduced species may even be harmful to the entire ecosystem because they can break the delicate equilibrium of the ecosystem.

what was the key factor that allowed Hershey and Chase to show that DNA alone carried the genetic information of a bacteriophage?
Explanation:
DNA contains phosphorus, but protein does not. Protein contains sulfur, but DNA does not. This allowed radioactive phosphorus and radioactive sulfur to identity each molecule specifically.
[tex] \mathbb \fcolorbox{green}{red}{ STAY \: STRONG}[/tex]
[tex] \mathfrak \fcolorbox{green}{red}{BE \: BRAINLY }[/tex]
In the DNA structure there is phosphorus present while protein does not contain phosphorus but it contains sulfur while DNA does not which allowed radioactive phosphorus and radioactive sulfur to identity each molecule specifically.
What is Hershey and Chase experiment?Hershey-Chase experiment was the final experiment which is also called as the Waring Blender experiment. In this experiment, they showed that phages only injected their DNA into host bacteria, and that the DNA served as the replicating genetic element of phages.
They used this experiment to prove that DNA is the genetic material. [tex]T_2[/tex] Bacteriophage that was grown in isotopic medium radioactively labels a specific viral component. Two types of isotopic media were used.
Viruses that were grown in radioactive sulfur (35S) contained radiolabeled proteins.Viruses grown in radioactive phosphorus (32P) had radiolabeled DNANext, the virus was allowed to infect a bacterium (E. coli) and the virus and bacteria were then separated through centrifugation. After centrifugation, the larger bacteria formed a solid pellet, while the smaller viruses remained in the supernatant. The pellet of bacteria was found to be radioactive when infected with 32P-virus (DNA), but not with 35S-virus (protein).
This provided proof that DNA was the genetic material because DNA had been transcribed into bacteria, not proteins.
Thus, in the DNA structure there is phosphorus present while protein does not contain phosphorus but it contains sulfur while DNA does not which allowed radioactive phosphorus and radioactive sulfur to identity each molecule specifically.

Describe the path of a phosphorous atom through four parts of the phosphorous cycle. Be sure to explain the processes involved in the transfers. Note when a form of phosphorous is available to plants. (Will mark brainliest)
Answer: One of the ways the path of a phosphorous atom starts is in a rock containing phosphate. The rock weathers, so that a phosphate ion enters the soil. A plant takes up the phosphate ion and incorporates it into a DNA molecule in a pollen grain. The grain falls back to the ground and decomposes, converting the atom back into phosphate through mineralization. The phosphate ion then leaches into the groundwater, leaving the soil.
Explanation: Plato/ Edmentum
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. Plants take up inorganic phosphate from the soil.
How does phosphorus enter the phosphorus cycle?
Phosphorus enters the atmosphere from volcanic aerosols. As this aerosol precipitates on earth, it enters terrestrial food webs. Some of the phosphorus from terrestrial food webs dissolves in streams and lakes, and the remainder enters the soil. Another source of phosphorus is fertilizers.
