redwood trees have more biomass than any other plant species in western redwood forests. they greatly impact the other plant and animal species that live in these forests. if removed, most understory plants and their associated herbivores could not survive. are redwood trees a keystone species? why or why not
a. Yes, redwood trees are a keystone species because they have a significant impact on the ecosystems in which they grow and their removal would lead to the decline of other plant and animal species.
b. No, redwood trees are not a keystone species because their biomass does not directly support a wide variety of other species in the ecosystem.
c. Yes, redwood trees are a keystone species because they are essential for the survival of many understory plants and herbivores in western redwood forests.
d. No, redwood trees are not a keystone species because they do not have a disproportionate effect on the ecosystem compared to other species present.
