The first and lowest level contains the producers, green plants. The plants or their products are consumed by the second-level organisms—the herbivores, or plant eaters. At the third level, primary carnivores, or meat eaters, eat the herbivores; and at the fourth level, secondary carnivores eat the primary carnivores.

Explanation:
There are dominant and recessive genes for both the hair color gene and the gait gene in horses, B, b, T and t respectively.
If a black trotter is heterozygous that means it's genotype is going to be Bb and Tt, therefore it will possess both dominant and recessive genes for the two traits.
The allele combinations in the gametes it produces can be BBTT, BBTt, BBtt, BbTT, BbTt, Bbtt, bbTT, bbTt and bbtt .

Answer:
The right answer is B. The offspring are genetically distinct ... by sexual reproduction.
Explanation:
Sexual reproduction, as opposed to asexual reproduction, indicates that the propagation of a species involves male and female gametes. It is the main method of reproduction of multicellular organisms.
In the first stage of sexual reproduction, meiosis, the number of chromosomes is reduced from a diploid number (2n) to a haploid number (n). During fertilization ("fertilization"), haploid gametes come together to form a diploid zygote and restore the initial number of chromosomes (2n).
