What advantage do organisms in a food web have over those in a food chain?
a. organisms in a food web have alternative foods to eat if one of their food sources diminishes or disappears.
b. organisms in a food web are on the highest trophic level of feeding stages.
c. organisms in a food web have equivalent survival rates to those in a food chain because they are herbivores.
d. organisms in a food web have one primary food source, which ensures their health.

A.Organisms in a food web have alternative foods to eat if one of their food sources diminishes or disappears.

Food chain refers to a process cycle from producer to consumer to decomposer.
Example:
Plants – herbivores – omnivores – carnivores Start -> Plants -> herbivore insect -> spiders -> small bird -> Snake -> hawk -> fox -> lion -> when died the body will be eaten by hyena-> when hyena died -> body get decompose and be eaten  by worms and the rest will be plant’s fertilizer.

The process of the food chain will then again takes place over and over again.
