HELP PLS! A biomass pyramid for a typical grasstand ecosystem is shown here. What explains the changes in mass seen in the pyramid from
the producer level to the next level?
A
The solar energy available to each trophic level in the pyramid decreases,
therefore the biomass of the organisms in each level continues to
decrease
B
The recycling of nutrients decreases at each level of the ecological
pyramid, decreasing the availability of matter and nutrients to each
successive level in the pyramid.
C
The decomposers digest the majority of the biomass of the primary
producers, leaving fewer components to be consumed by the herbivores.
This limits the growth of the herbivores to always be less than that of the
primary producers.
D)
The primary producer level has more biomass than the primary consumers.
Primary consumers cannot consume all parts of the grasses, such as the
roots and dead leaf litter. Therefore, the biomass of the primary consumers
will always be less than the biomass of the primary producers.

Nhumans, abo blood types refer to glycoproteins in the membranes of red blood cells. there are three alleles for this autosomal gene: ia, ib, and i. the ia allele codes for the a glycoprotein, the ib allele codes for the b glycoprotein, and the i allele doesn't code for any membrane glycoprotein. ia and ib are codominant, and i is recessive to both ia and ib. people with type a blood have the genotypes iaia or iai, people with type b blood are ibib or ibi, people with type ab blood are iaib, and people with type o blood are ii. if a woman with type ab blood marries a man with type o blood, which of the following blood types could their children possibly have? in humans, abo blood types refer to glycoproteins in the membranes of red blood cells. there are three alleles for this autosomal gene: ia, ib, and i. the ia allele codes for the a glycoprotein, the ib allele codes for the b glycoprotein, and the i allele doesn't code for any membrane glycoprotein. ia and ib are codominant, and i is recessive to both ia and ib. people with type a blood have the genotypes iaia or iai, people with type b blood are ibib or ibi, people with type ab blood are iaib, and people with type o blood are ii. if a woman with type ab blood marries a man with type o blood, which of the following blood types could their children possibly have? a, b, ab, and o ab and o a, b, and o a and b
