Keystone species are those that are a necessary component to the stability of the ecosystem, and without them, many other organisms would not survive and the ecosystem can collapse. Which of these is NOT an example of a keystone

species and the role it plays in Georgia's ecosystems?

-0)

A)

beaver; their dams create small ponds to help other species have a place to

Live and helps to stimulate the growth of plants

B)

kudzu; kudzu was introduced from Japan as an ornamental plant, and the

Civilian Conservation Corps used it to help reduce soil erosion

alligators; their tails dig holes that hold water during times of drought, and

this water is used as a source for drinking water by many species

D)

red cocaded woodpecker; they drill deep nests into Georgia's pine trees,

and when not in use by the woodpecker, many other organisms will use

them

The correct answer is - option C. alligators; their tails dig holes that hold water during times of drought, and  this water is used as a source for drinking water by many species.

Explanation:

Beavers are keystone species as they help other species to get habitat and also help plants to grow by the holes or dams they make. Kudzu is a keystone species of an ornamental plant which lowers the soil erosion in their abundance.

Red cocaded woodpecker is a keystone species as they create pits in the pine trees that are helpful for other species to live.

Alligators also keystone species but not for digging holes and hold water but the influencing the prey and maintaining the animals in the ecosystem.

so whats the answer

ans.

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.'
