Which shows the most direct path that carbon can take through the carbon cycle? plant ® atmosphere ® animal animal ® plant ® atmosphere plant ® animal ® atmosphere atmosphere ® animal ® fossil fuel

One of the many paths a carbon molecule can take through the carbon cycle is by the carbon molecule taken by plants through the process of photosynthesis, then the plants carbon molecule can turn into oxygen. Then an animal or primary consumer can eat the plant.

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.
