A primary consumer is an organism that feeds on primary producers. Organisms of this type make up the second trophic level and are consumed or predated by secondary consumers, tertiary consumers or apex predators.

A food chain is the sequence of who eats whom in a biological community (an ecosystem) to obtain nutrition. A food chain starts with the primary energy source, usually the sun or boiling-hot deep sea vents. The next link in the chain is an organism that make its own food from the primary energy source -- an example is photosynthetic plants that make their own food from sunlight (using a process called photosynthesis) and chemosynthetic bacteria that make their food energy from chemicals in hydrothermal vents. These are called autotrophs or primary producers.

Next come organisms that eat the autotrophs; these organisms are called herbivores or primary consumers -- an example is a rabbit that eats grass

3. There is a gene that affects pea pod color and has two alleles: G = yellow and g = green. There is another gene that affects
Lena [83]

A. Mendel in his experiments used two true breeding plants that only express one particular trait. He would chose plants with different versions of the trait and cross pollinate them. So, in this case, Mendel’ s P generation would be:

P: GGWW  x  ggww

B. The possible gametes produced by these first or original parent plants (GGWW and  ggww genotypes of the parents) are:

GW and gw. When an organism makes gametes, each gamete receives just one copy of the gene, which is selected randomly (Mendel’s law of segregation).

C. If the gametes GW and gw are joined, the genotype in the offspring would be GgWw. This is dihybrid organism because it is heterozygous (have two different allelss, one recessive, one dominant) at two different genetic loci, G and W. The offspring represents the F1 generation.

D. If the individuals with the genotype GgWw are crossed with the individuals with the same genotype (GgWw), the possible gametes are GW, Gw, gW, gw. The possible genotypes for the F2 generation are:  GGWW, GGWw, GgWW, GgWw, GGww, Ggww, ggWW, ggWw and ggww. There are nine different genorypes. The genotypic ratio is 1:2:2:1:4:1:2:2:1.

E. F2 generation of offspring of this dihybrid cross has a 9:3:3:1 phenotype ratio. Mendel did similar experiment with his plants and conluded that the pairs of traits in the parental generation (P generation) sorted independently from one another, from one generation to the next.
