d. most producers are inedible.
ANSWER:
Step 1 of 2
We'll be exploring the reasons behind the varying lengths of food chains. Four potential explanations have been proposed:
Answer A postulates that the brevity of a food chain may be due to a singular herbivore species consuming each plant species. However, this doesn't often limit the food chain's length, as many ecosystems have herbivores with varied diets that encompass several plant species, even if they have favored plants.
