The day-neutral plants will undergo flowering at any length of the day, given that there is the availability of minimum amount of light, which is essential for usual growth. For example, beans, tropical plants, cotton, and others.
On the other hand, the intermediate-day plants will not flower if the days are too long or too short, like different varieties of grasses.
I picked Ecological diversity. This refers to the different kinds of ecosystems in a biome or other localized area, like species diversity refers to the number of species in an area. Ecological diversity<span> is also the largest scale of biodiversity, and within each </span>ecosystem<span>, there is a great deal of both species and genetic </span>diversity<span>.</span>
Answer:
