Ecosystem is a community or group of living organisms that live in and interact with each other in a specific environment.
An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system. These biotic and abiotic components are linked together through nutrient cycles and energy flows.
Fahrenholz's rule is supported when: comparison of phylogenies for host and parasite show a correlated pattern of evolution
<h3>What is Fahrenholz's rule ?</h3>
The close correspondence is observed between the taxonomy of parasites and their hosts and this has led to Fahrenholz's rule. This rule postulates that parasites and the hosts speciate in synchrony.
This leads to a prediction that phylogenetic trees of parasites and their hosts are topologically identical.
when the only events in the process of reciprocal natural selection in the host and parasite lineages were those of contemporaneous speciation in both the lineages then host and parasite phylogenies are fully congruent, hence supporting Fahrenholz'srule.

Not sure but b or c but lmk
The organism underwent an insertion mutation because the C was inserted into the codon which will throw off the balance of the other codon and make it code for something completely different
Generation-to-generation change in the allele frequencies in a population is _____.
a. genetic drift b. natural selection c. macroevolution d. mutation e. Microevolution
Answer:
e. Microevolution
Explanation:
Microevolution refers to the small changes in the allele frequencies and the genotype frequencies of the populations. These changes occur over a few generations and deviate the populations from the genetic equilibrium.
The processes responsible for microevolution are mutations, genetic drift, gene flow, etc. Similarly, sexual selection and nonrandom mating also change the allele frequencies of the populations. Likewise, natural selection brings about microevolution by increasing the frequencies of the alleles that impart the beneficial traits to the organisms.
