Question

How can extinctions and expansions occur in the same habitat? Explain your answer.

Answer 1

When a habitat is destroyed, the carrying capacity for indigenous plants, animals, and other organisms is reduced so that populations decline, sometimes up to the level of extinction. Habitat loss is perhaps the greatest threat to organisms and biodiversity.Extinction happens when environmental factors or evolutionary problems cause a species to die out. The disappearance of species from Earth is ongoing, and rates have varied over time.

Answer 2

Extinctions are associated with biodiversity changes, thereby affecting species expansion.

What is extinction?

Extinction refers to the disappearance of a given taxonomic group (e.g. species-level extinction).

• This process of disappearance (extinction) modifies the trophic relationships in the ecosystem.

• The modification may lead to the expansion of a given species (e.g., prey in the case of predator extinction).

In conclusion, extinctions are associated with biodiversity changes, thereby affecting species expansion.
