Answer:
If the grasshoppers are removed from this ecosystem the bird will suffer the most.
Explanation:
On the presented food web we can see a food web that is complex and typical for the African savanna. As in all food webs, one organism is important for the survival of another organism or for the survival of numerous organisms. In this case, we have the grasshopper and its importance in the ecosystem, and which animal will be the most affected if it suddenly was not in this ecosystem anymore.
The bird and the baboon both feed on grasshoppers, but there is one big difference, and that is that the grasshoppers are the primary food source of the bird, while the baboon has other food sources as well. This means that with the grasshoppers being out of this ecosystem, the bird will have a very hard time surviving, and if it doesn't adapt quickly enough to feed on something else it will probably go extinct. The baboon, on the other hand, will be affected but not so dramatically as it will continue feeding on the other food sources, though it might suffer some smaller losses in its population.

The Pacific white-sided dolphins are well adapted to live in their environment. Two adaptations of the dolphins are:
1. Perfect Swimmers: The Pacific white-sided dolphins are perfect swimmers and they swim extremely well. they are very fast swimmers.
2. Sleeping with half a mind: Dolphins do not sleep completely. Half of their minds are always awake and they are attentive even when sleeping. This helps them from drowning in water.
