Regrowth of grasses, ferns, wildflowers, and saplings after a forest fire is an example of secondary succession.
Secondary succession is one of the two main forms of ecological succession of plant life that is initiated by an occurrence such as harvesting, or forest fire, that has a negative impact or diminishes an already established ecosystem such as a forest or a wheat field to a lower number of species. Several factors such as initial composition, trophic interaction, and competition-colonization trade-offs can influence secondary succession.
Answer:
In the initial stages of digestion of food, the stomach performs an essential role. Apart from doing churning and squeezing the food bolus, it also discharges an amalgamation of compounds, together called gastric juice. It comprises mucus, water, pepsin, HCl, and intrinsic factor. Of these five constituents, the principal enzyme that takes part in the digestion of protein is pepsin.
It dissociates proteins into amino acids and smaller peptides, which can easily get captivated within the small intestine. This pepsin is released in its sedentary form, or zymogen form called pepsinogen by the chief cells present within the gastric lining. It is released in its sedentary form by the stomach, by this the stomach inhibits the auto-digestion of defensive proteins in the digestive tract's lining.
Answer:
A. longer pregnancies & periods of infant dependency
Explanation:
Primates are known to mature slowly compared to other mammals, they have a longer gestation period and longer period of infant dependency. Therefore the period between birth and adulthood is usually longer compared to other mammals, which then result to late age in their first reproduction.
For example humans have a gestation period of 365 days while baboons is 187 days compared to rabbits with a gestation period of about 33 days or mice with a gestation period of about 20 days
Of any primate, humans exhibit the longest period of infant dependency, Chimpanzee is about 5 years compared to other mammals.
