Answer:
The model representing this relationship is : Prey-Predator Relationship.
Explanation:
- In a prey-predator relationship, the population size of each, prey and predator is affected by the population of the other.
- This is distinctly observed when the predator has a preference for a particular prey.
- In the given example, the rabbits are the prey and the foxes are the predators.
- Increase in the population of the rabbits will make them easily accessible to the foxes, that on hunt them for their food.
- On obtaining sufficient food the foxes can reproduce well and will produce more offspring, so the population size of the foxes would also increase.
- After some time, the continued hunting of the rabbits will cause its death rate to increase more than its birth rate. This will result in the decline in the rabbit population.
- The reduced rabbit population would reduce the chances of them being accessed and hunted by the foxes.
- Due to decrease in food availability, the foxes reduce their reproduction rate, as a result the fox population gradually decreases.
- This is followed by an increase in rabbit population.
- This cycle continues.
Answer:
Imagine what would happen if there were no decomposers. Wastes and the remains of dead organisms would pile up and the nutrients within the waste and dead organisms would not be released back into the ecosystem. Producers would not have enough nutrients.
Plant cells also have features that animal cells do not have: a cell wall, a large central vacuole<span>, and plastids such as </span>chloroplasts<span>.</span>
Answer: DNA replication
The polymerase chain reaction or PCR is a process similar to the DNA
replication but using the machinery of heat-resistant bacteria, resulting in millions of copies of a specific sequence of DNA. That sequence can later be seen through electrophoresis. Both the PCR and the DNA replication of the cell lead to copies of DNA template.
Based on the graph the region expected to have the least population growth will be Australia.
<h3>Graphical illustrations</h3>
Looking at the given graph the population size of each region starts at a lower point and ends at a higher point on the graph between the years 1950 and 2050.
The change in the population also varies depending on the scale on the y-axis. Australia has the lowest scale which lies between somewhere above 10 and 50.
