There's an excess of Phosphorus in soil, the plants consume it, then the primary consumers consume multiple plants, and have a higher level of phosphorus concentration in them. Then secondary consumers consume multiple primary consumers and the phosphorus from all the things they ate are concentrated in them, and so on. Basically, even though as energy is passed along the food chain, it lessens with each trophic level, nutrients become more concentrated and the highest trophic level has the highest concentration because of how many organisms were consumed.

Which statements describe incomplete dominance?

irga5000 [103]

Ans.

Incomplete dominance is defined as a pattern of inheritance, in which both of the alleles for a specific trait get expressed in offspring (neither allele is dominant or recessive).

It result in appearance of an intermediate, third phenotype or physical trait that shows combination of traits of both alleles.

For example, a cross between red colored and white colored flower of 4' O clock plants results in offspring plants with pink colored flowers

Thus, the correct options are :-

-Traits are neither recessive nor dominant.

-Offspring show an intermediate trait of alleles from the parents.

-Both alleles, one from each parent, get expressed in offspring.

-Incomplete dominance involves the interaction of two alleles.
