Factores bióticos en los ecosistemas

Ecosystems are vulnerable to changes, whether abiotic or biotic. A small change can destabilize the entire system, affecting food sources and habitats. The introduction of new species, like rabbits in Australia, can lead to habitat destruction and species loss. Similarly, introducing parasites and diseases can be catastrophic. Removing predators allows prey populations to grow uncontrollably, further disrupting ecosystems. Even minor changes can have significant impacts over time.

What can happen if a species at the base of the food chain disappears?

• The food chain becomes stronger.

• Other species may also disappear.

• The ecosystem becomes more stable.

• New species are introduced automatically.

Why did the rabbit population in Australia grow so rapidly?

• They faced no predators and had ideal conditions.

• The climate was too harsh for them.

• They were controlled by human intervention.

• They had many natural predators.

What is a potential consequence of introducing a new species to an ecosystem?

• It only affects the abiotic factors.

• It always benefits the native species.

• It has no impact on the ecosystem.

• It can lead to the extinction of native species.

What can result from the removal of a predator in an ecosystem?

• The prey population decreases.

• The ecosystem becomes more balanced.

• New predators are introduced immediately.

• The prey population grows uncontrollably.

How long can it take for biotic changes to manifest in an ecosystem?

• They can take many years.

• They are always immediate.

• They never manifest.

• They only manifest in a few days.
