Alocal area contains a stable desert biome. the
residents often use hiking trails through the dessert for
exercise. many of the residents complain about the
numerous cacti in the area, stating that their pets
often get too close they get cactus needles stuck on
their face causing injury. the residents have
suggested removing all the cacti from the area. the
city council is considering this and has consulted a
local ecologist who has constructed the food web
shown. which of the following statements correctly
identifies a concern the ecologist may have about the
proposed plan?
a. grasshoppers will no longer have a food source.
b. more of the available energy in the food web will
be lost metabolism.
c. the removal of producers will affect all other
trophic levels.
d. more grass will grow eliminating the desert
environment.

Option(C)

The removal of producers will affect all other trophic levels

Explanation:

Consider a food web where Cactus (producer) --> grasshoppers (primary consumer) --> frogs (secondary consumers). If the ecologists have decided to cut off all the cactus in the area, it would result in collapse of the entire food web.

The primary consumer i.e., the grasshoppers which feed on producers, i.e., the cactus would die off. The next to be affected would be the secondary consumer, i.e., the frog. In this way, the whole trophic level would be disturbed.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
