Over long periods of time, species interacting within an ecosystem develop close

Question

Over long periods of time, species interacting within an ecosystem develop close interdependence. Occasionally. two species become so dependent upon each other that each directly affects the others evolution, a process called coevolution. Hummingbird pollinated plants have evolved long, red, tubular flowers that provide a lot of nectar in order to attract hummingbirds. What do the plants gain by doing this that they would not otherwise have without it? Along the Pacific Coast of North America, mussels abound on the shoreline rocks of the intertidal zone. In that ecosystem, the sea star (starfish) is a keystone species because: Sea stars keep other species away Sea stars eat all the mussels Sea stars eat some of the mussels, which provide room for other species to live on the rocks along with the mussels. The sea star is not a keystone species in that ecosystem

Explanation / Answer

15Q

Answer:

In the evolutionary processes, every organism tries to fit, survive and replicates to cope up with the harsh environmental conditions, like wise plants also do the same.

To attract the hummingbirds, such plants evolved long, red and tubular flowers, if there were no hummingbirds, plants would have evolved other mechanisms to pollinate themselves.
