Here is your essay on Amensalism !Contrasting with commensalism is amensalism, a situation in which one population definitely inhibits the other while remaining unaffected itself. By so modifying the environment, the organism improves its own chance of survival.Ammensalism commonly involves some type of chemical interaction, by which the organisms of one species affects the well-being and growth of individuals or the population biology of other, is called allelochemic (see, Whittaker, 1970, smith. 1974, Kendeigh, 1974). Thus, chemicals released by one species, which act on the growth, health, and behaviour of another species, are called ailelochemicals. Allelo- chemical effects are of three general sorts: allomones, kairomones and depressants. image source: upload.wikimedia.org ADVERTISEMENTS: Allomones are chemicals which give adaptive advantage to the organism that produces the chemical. Examples include repellents, which provide…

There exists a specific relationship between marginal cost curve and average total cost curve. Irrespective of any influence, marginal cost curve intersects the average total cost from below at the lowest point of the average total cost curve.Average total cost falls when marginal cost is less than the prevailing average total cost, and average total cost rises when marginal cost is greater than the prevailing average total cost. ADVERTISEMENTS: To the left side of Q, marginal costs are smaller than average total costs causing average to decline (figure 9.6). Likewise, to the right side of Q, marginal costs are higher than average total costs causing average to increase.The relationship between marginal cost and average cost can be easily established with the help of simple arithmetic. Suppose, a student obtains 60…
