Which statement describes a situation that leads to stability within an ecosystem?

Carbon dioxide and water are released only by abiotic sources in the ecosystem.

Interactions between biotic and abiotic components regulate carbon dioxide and water levels.

Animals provide the oxygen used by plants, and plants provide the nitrogen needed by animals.

Organisms provide all the necessary energy for the maintenance of this ecosystem.

Interactions between biotic and abiotic components regulate carbon dioxide and water levels.

Explanation:

Abiotic factors include temperature, water, humidity, etc; while biotic factors include all the forms of life. These factors interact in the ecosystem to maintain its homeostasis. For example, during the photosynthesis, plants use the energy of the sun water and carbon dioxide to produce food (carbohydrates) and this process converts carbon dioxide (CO2) to oxygen, which is critical for maintaining the homeostasis of the ecosystem.

answer: land bridge theory. land bridge theory held that shifting portions of dry land explained the finding of identical species on different continents. plate tectonic theory eventually eliminated the land bridge theory.
