But what if all primary consumers became extinct...?
If all primary consumers were to become extinct:
Entire food web would most probably collapse
To begin with, secondary consumers that fed off these primary consumers would increase intraspecific and interspecific competition and at some point run out of enough sources of food, which would lead to a rapid decrease in population, obligate them to search for other diet alternative and finally, and more drastically , extinction.
Tertiary consumers that fed off secondary consumers would then drastically be affected in the same way primary consumers did and finally become extinct.
Producers would increase population rapidly, changing he physical environment drastically and becoming it inhabitable for some species. Intraspecific and Interspecific competition would also become an issue between producers, and at some time this would lead to the ‘survival of the fittest’ among producers as overpopulation would leave no other alternative.
At some point, the entire food web would collapse due to this unbalanced growth in population and competition.
what would happen if all the decomposers became extinct?
If all decomposers became extinct...
Dead remains in nature would accumulate
Because dead material is not decomposed, soil fertility would not be possible
As a result of soil infertility plants would not be able to grow.
Hence, with no producers primary consumers would starve and become extinct.
Moreover, no primary consumers, no secondary consumer, no secondary consumers, no tertiary consumers etc. until the food web collapses.
If a non native species severely depleted the population of producers in this rainforest food web....
Primary consumers like spider monkeys, toucans, capibaras, and ants would have a great intraspecific and interspecific competition increase, as food (producers) is not abundant anymore, yet, still vital for their survival. At some point, the food source wont be able to sustain these primary consumers and will eventually cause them to decrease dramatically in population (may even lead to extinction in extreme cases), either out of starvation or migration in search of other diet alternatives. This would be the same for the rest of the food web (secondary consumers, tertiary consumers). However, the decay of matter from the increased dead material (dead consumers) would increase soil fertility and therefore increase producers population, balancing the food web and bringing balance to all population numbers.
Explain why food webs with many species are more resilient than those with few species.
food webs with many species are more resilient than those with few species because...
The more complex a system is, the more sustainable it is.
Food webs are a kind of systems in which:
less diversity of species means that the loss or fluctuation of one of the species will cause a tremendous impact on the rest of the food web.
less diversity means less options
Whereas if the food web contains a high diversity of species, fluctuations like changes in population numbers of one species is more likely to create a insignificant change for the rest of the food web.
Resilient food webs with higher diversity (options) are more flexible to changes and are more likely to go back to their initial sustainable state despite fluctuations in the system.
