Question

Which one of the following animals is most likely to be a keystone species, based on the food web provided? Frog? Dear? Grasshopper? Mouse? The food web shows a tree and grass at the bottom. There are arrows pointing from the tree and grass, these arrows point to a mouse, a. Grasshopper, a. Squirrel, and a deer. There is arrows pointing from the grasshopper. They are as pointing from the grasshopper point to a mouse, a whip tail, and a frog. There are arrows pointing from the deer, the arrows pointed from the deer point two a mountain lion and a wolf. There is arrows coming from the squirrel. The air is coming from the squirrel point too a pine marten, an eagle, and a ringtail. There are lines coming from the frog. The lines from the frog point too, a eagle, a. Ringtail, and a pine martin. There are arrows coming from the mouse, they point to a ringtail, an eagle, and a pine Martin. There are arrows coming from the whip tail, the arrows point two and eagle. That's it. There are arrest pointing from the ringtail, those arrows point to a wolf, a mountain lion, and a bobcat, there are arrows coming from the pine Martin, those arrows point two a bobcat, a mountain lion, and that's it. There are arrows coming from the bobcat those arrows point two a wolf and that's it. The Wolf mountain Lion bobcat and eagle have no arrows pointing at them meaning they have no predators

Answer 1

The frog is most likely to be a keystone species in this food web. Keystone species are those that have a disproportionately large impact on the ecosystem in relation to their abundance. In this case, the frog is connected to multiple other species in the food web, including the eagle, ringtail, pine marten, and mouse. If the frog were to be removed from the ecosystem, it could have significant cascading effects on the populations of these other species. This indicates that the frog plays a crucial role in maintaining the balance of the ecosystem and is therefore a keystone species.
