The main source of carbon dioxide in an ecosystem is the carbon dioxide gas present in the atmosphere. This carbon dioxide is used by the plants and animals in different ways.
The plants use this carbon dioxide to perform the process of photosynthesis.This is carried out by the help of green pigment called chlorophyll that absorbs light from the sun, water from soil and carbon dioxide from atmosphere.
The carbon in animals comes when they eat these plants.
Two diverse species naturally breed an offspring, and selective preserves raver new traits in a given environment, (they evolve).
I hope this helps.=^⊃
Genotype - RR - 25%, Rr - 50%, rr - 25% (1:2:1)
Phenotype - Round seeds - 75%, Wrinkled seeds - 25% (3:1)
<h3>How explain your answer?</h3>
Let the letter "r" stand for the alleles, where R is round seeds and r is wrinkled seeds. A genotype is an individual's genes represented through alleles. Phenotypes are how the genes express themselves. In other words, genotypes will be written using letters, the alleles, and phenotypes will be the possible outcomes of the alleles.
Both of the parent seeds have the genotypes Rr and the phenotype of round seeds.
If you create punnet square (which had four boxes in total) 1 will have RR, 2 will have Rr, and 1 will have rr. These are the ratios for the genotypes. Each box represents 25%, so the percentages will be 25, 50, and 25. Finally, 3 of these boxes (RR and Rr) will result in round seeds because those are dominant. Only the genotype rr will result in wrinkled phenotype. Therefore, the ratio is 3:1 or 75% to 25%.
Thus, this could be the answer.
