multidirectional
Explanation:
if it is a food chain it is unidirectional. But since it's Ina food web it's multidirectional because a food web is an interconnection of different food chains.
And different organisms feed on other different organisms. For example; a rat can eat a grasshopper then it is eaten by either a fox or a snake the fox and the snake can be in different food chains but in a food web they are two organisms that both feed on the rat

Answer:
Quorum sensing is triggered to begin when<u> a sufficient number of bacteria are present .</u>
Explanation:
Quorum sensing -
Quorum sensing is the ability to detect and to respond to the cell population density by the process of gene regulation . Quorum sensing bacteria releases some chemical signal molecules called the autoinducers , that increases the concentration as the function of the cell density .
The detection of the minimum threshold concentration of an autoinducer leads to the alteration in the gene expression .
