I believe the answer is Offspring that fail to develop. Post-fertilization barriers is where fertilization occurs but hybrid cannot reproduce. There two types of post fertilization barriers; Hybrid in-viability where the Zygote cannot complete development b/c genetic instructions are incomplete. The other one is Hybrid sterility where the hybrid organism cannot produce offspring b/c chromosome number is odd.

Explain why increased ecosystem diversity contributes to increased biodiversity in the biosphere answer
Alisiya [41]
A diverse set of ecosystems means that there will be a wide variety of selection pressures exerted on the organisms. Therefore, natural selection will act to bring out the best suited traits for that particular ecosystem. The more the ecosystems are diverse, the more will be the difference between the traits between the organisms that will survive. This means that the biodiversity will increase.
