from the short film some animals are more equal than others: trophic cascades and keystone species:
true/false: all members of a food web are equal in abundance and in their relative effects on one another.
true
false

Explanation:

In a food web, species have different abundances. For example, producers (like plants) are usually more abundant than top - level predators. Also, their effects on one another are not equal. Keystone species, like sea otters in a kelp forest ecosystem, have a disproportionately large effect on the community structure relative to their abundance. Removing a keystone species can cause major changes in the food web, while removing a less influential species may have a smaller impact.

Answer:

False
