Which of the following organisms is most likely to survive?
a. the producers in a food web
b. the top carnivore in a food chain
c. a herbivore in a food chain
d. the top carnivore in a food web

The producers in a food web. Following the 10% rule, not only does the top carnivore get the least amount of calories from the food web, but is subject to dying based on one animal dying out, affecting the rest of the food chain. However, because the producers are autotrophic, they only rely on the sun, and therefore, are more likely to survive since they don't rely on any other living organism.

Yes yes yes very good
