galben [10]

The scientific law of one organism feeding off other where energy is transferred from one form to another is known as the law of conservation of energy.

<h3>How the sun is the primary source of energy for ecosystems?</h3>

Energy from the highest energy source that is sun is absorbed by plants to convert it into food (i.e a form of energy). plants are the only ones that can convert sunlight into another form of energy directly.

The animals and organisms that feed off of the plants take some part of this energy for their life cycles and then the animals that feed off of these animals again take some part of this energy and carry on with their life cycle, this is how energy from sun (highest source) is transferred to different organisms by Just changing form.

Thus, The scientific law of one organism feeding off other where energy is transferred.

What was Mendel's explanation for the fact that 0% of the offspring from this cross were green?
VMariaS [17]
So Mendel got roughly 75% yellow and 25% green in f2. This means that f1 contains all heterozygous genes, as shown below

Y y
Y YY Yy
y Yy yy
Summary: 75% YY or Yy, 25% yy

Which means that green (y) is a recessive phenotype, while yellow (Y) is a dominant phenotype, since plants with heterozygous genotype Yy express the yellow trait.
