The correct answers are:
B) Predation;
C) Decomposition;
The fungi are found in many different forms, and they practice numerous styles of life. The fungi can be considered as organisms that are decomposing. They are actually the main living organisms that take advantage of the decomposing organisms, but they too find themselves in a situation where they decompose once their life is over. Also, some fungi, around 150 species from what is known so far, are actually predators. They are feeding on nematode worms. They have developed ways to trap the worms, or just simply snag them with an adhesive that sticks to them.
The fungi though can not be considered as autotrophs. The reason for that is that they are not producers, but instead they use the producers as food source, thus making them heterotrophs.
Nitrogen Cycle steps:
N molecules breaking apart via nitrogen-fixing bacteria.
Animals ingest nitrogen in nitrate-containing food after plants use nitrogen-containing compounds.
The organic matter decays via decomposers
N2 is formed via denitrifying bacteria.
Explanation:
The nitrogen-fixing bacteria removes atmospheric nitrogen by fixing nitrogen through nitrification. The atmospheric nitrogen cannot be absorbed by plants and hence has to be converted into nitrates. This conversion takes place by nitrifying bacteria present in leguminous plants.
Animals (herbivores) consume the plants that have absorbed nitrogen/
When these animals die, decomposing bacteria acts on the dead organic matter, decomposition takes place through ammonification, converting the organic nitrates into ammonia
The nitrates are converted back again to nitrogen by the action of denitrifying bacteria.
The nitrogen thus formed is released to the atmosphere
Haploid cells join to form an organism that has a complete set of chromosomes
If a cat does not chase a laser, does that really qualify it as a broken cat
Answer: Only Options A, C and E are correct
A) Sympatric speciation is best described as a random event that disrupts the allele frequencies in a population
C) Sympatric speciation does not require geographic isolation.
E) Sympatric speciation can be due to sexual(mate) selection
Explanation:
Sympatric speciation is a random or naturally occurring event whereby organisms of the same species:
> live in the same territory or nearby territories ( i.e not living in isolation)
> DO NOT interbreed, but select a sexual mate from a much diverse territory which results in an uneven gene flow or disruption of alleles among the population of same species of the parents organisms.
