Name the three types of population distribution, describe each, and explain the conditions that govern each.

tankabanditka [31]

Answer: Population distributions may be described as random, uniform or clustered.

Explanation:

In a specified region, a population comprises any number of members of the same species. Populations are described by sizes- the number of individuals; densities- individuals in a set space (per unit area); and distribution- the dispersal or non dispersal of individuals (spread out or clumped). Population distributions may be described in three ways:

Random: the distribution pattern is haphazard, with no regular spacing; individuals grow independently of each other without competing and resources are consistent. E.g. dandelion seed dispersal by wind

Uniform: individuals are evenly spaced in a predictable pattern; there may be some interaction and ideally, spaces between them are maximized in order to ensure access to limited nutrients and resources. E.g. human farming- cornfields, orchards; allelopathy in plants like purple sage, which secretes chemicals to prevent the growth of other plants nearby

Clumped: there is less distance between neighboring organisms and these individuals cluster together. This pattern is most common in environments where resources are scarce, or the species is dependent on social interactions. E.g. lions are highly social and hunt in prides in the wild

Which of these statements is not correct regarding our limbic system? which of these statements is not correct regarding our lim

givi [52]

I believe the answer is Sights often create strong emotional responses. This is not true since the sense of smell is more directly attached to the limbic system and is therefore more likely to cause emotional response. The limbic system is a set of brain structures located on both sides of the thalamus, beneath the cerebrum. it supports functions such as emotion. behavior, motivation, long term memory and olfaction.
