Answer:
b. the new species must be unable to breed with the original species.
Explanation:
By definition, species are defined as groups of similar organisms that can live and breed freely. This means that individuals in that species can interbreed and produce viable, fertile offspring. However, two different species cannot interbreed to produce fertile offspring due to biological barriers known as mechanisms of reproduction isolation.
These barriers are broadly classified as pre and postzygotic. Prezygotic barriers include the following:
- Habitat isolation: Two species occupy entirely different and distant habitats.
- Temporal isolation: Two species procreate at different times of the year.
- Behavioral isolation: Two species exhibit different mating behaviors.
- Gametic isolation: The gametes of the two species cannot fertilize.
- Mechanical isolation
Speciation, the production of an entirely new species, requires a maintenance of genetic diversity. Therefore, the new and original species cannot interbreed as this would limit the gene pool and decrease genetic variations.
Answer: In addition to slowing the overall expansion, gravity causes local clumping of matter into stars and galaxies. ... Within the Local Group, the gravitational interactions have changed the inertial patterns of objects such that there is no cosmological expansion taking place.

THE ANSWER ISSSSSSSSS HOST
Explanation:
No. Producers and consumers make the some way 'the food chain' and if one of them dies the other one will be affected and then dies.
