Two species of a plant genus ipomea share a common niche and reproductive pattern but are still unable to hybridize because they have structurally different flowers. what kind of reproductive isolation is observed in these two species?

mechanical

temporal

behavioral

The answer is mechanical isolation

Explanation:

Isolation is defined as the ecological, anatomical, physical or functional barriers that prevent reproduction between individuals of different species. In the specific case, it refers to a mechanical isolation is defined as the lack of a correspondence between the structure of the genital organs, in the specific case, either the isolation because of having differences between the means of pollination.

humans can cause extinction of a species through overharvesting, pollution, habitat destruction, introduction of invasive species (such as new predators and food competitors), overhunting, and other influences. explosive, unsustainable human population growth is an essential cause of the extinction crisis.

glacial erosion, the picking up and movement of earth beneath a glacier, is also referred to as plucking. erosion and transportation of individual pieces of bedrock, especially large "joint block occur as a result of this glacial erosion. plucking is type of erosion in which rocks become frozen into the bottom and sides of the glacier.as the glacier moves downhill it 'plucks' the rocks frozen into the glacier from the ground.
