Question

biodiversity check-in
which food web shows greater biodiversity?
image of two food webs, a and b
options:

• food web a because there are more herbivores.
• food web b because there are a large variety of biotic factors shown.
• food web b because there are fewer food chains represented.
• food web a because it has a large amount of grasses.

Explanation:

Biodiversity in a food web is related to the variety of biotic (living) factors (species, their interactions). Food Web B has more different organisms (producers, consumers) and more complex interactions, showing a larger variety of biotic factors. Other options: "more herbivores" (A doesn't have more), "fewer chains" (less diversity), "large grass" (grasses are one producer, not diversity of biotic factors). So the correct reasoning is about biotic factor variety in Food Web B.

Answer:

Food Web B because there are a large variety of biotic factors shown.
