The correct answer is A) The forest ecosystem, because most of the animals can eat other organisms.
Explanation:
The web food of the forest ecosystem shows only crickets and mice need exclusively grass, while in the grassland ecosystem there are four different animals that feed exclusively on grass. Also, in the grassland ecosystem, these four organisms are the food for other animals. This means if there was no grass all organisms in the web will be negatively affected.
This phenomenon would not occur in the forest ecosystem because even if crickets and mice cannot feed on grass and they disappear in the ecosystem, their predators such as raccoons or skunks can eat other organisms such as ducks or squirrels that do not depend on the grass. Moreover, organisms such as butterflies or mosses that depend on grass and other types of vegetation can survive. According to this, the ecosystem that would most likely survive is the forest because most animals can eat other organisms (Option A.)
