Tryptophan self-controls its synthesis. If we have a large amount of tryptophan in the sense that it exceeds, tryptophan would act as a co-repressor which prevents synthesis of more enzymes for its production. Hope this answers the question.
background info:
Digestive system in animals is an important system in the context of digestion of ingested food into simpler forms that could be easily absorbed by the body cells.
This provides all the essential compounds needed by the body for the existence and development of the living organism. Different digestive systems have evolved according to different species, their feeding patterns, and their habitats.
answer:
Ruminant species survive only on plant matter. They are herbivorous animals.
Therefore, the digestive system of ruminants is evolved with the presence of a rumen which is a complex stomach with four different compartments.
Humans are omnivorous who depend on plant and animal matter both thus, their digestive system composes of one stomach.
This is the key difference between digestion of humans and ruminants.
hope this helped
Answer:
Biodervasity.
Explanation:
The term refers to the variety of life on earth.It demonstrates the extent of variation at different levels of species,genetic and ecosystem in a community of organisms.
It not equal in its distribution on earth;but rather varies with the type of ecosystem available and the distribution of biotic and abiotic factors in the ecosystem. For example;
It is highest in the Tropics,due to the species richness and diversity of the region. However, it varies in other ecosystem based on species diversity peculiar to parts of the region .e.g it is highest in the marine ecosystem along the coast of abundant temperature for primary producers.
