According to the principles of ecosystem dynamics, what is the most direct consequence when an external factor, like a sudden storm, disrupts a stable system?

The ecosystem immediately and permanently collapses.

The rates of birth and death become unequal.

All organisms in the ecosystem evolve new traits instantly.

The birth rate and death rate both increase at the same pace.

A severe drought significantly reduces the amount of grass available in a savanna ecosystem. What is the most likely initial impact on the population of herbivores, like zebras, that feed on this grass?

The birth rate will dramatically increase as zebras reproduce more to ensure survival.

The population size will remain exactly the same, as the ecosystem is too strong to be affected.

The death rate will likely increase due to starvation, causing the population to decrease.

The zebras will instantly evolve the ability to eat other types of plants or animals.

The ecosystem has returned to its exact pre-fire state.

A new equilibrium has been reached under the new conditions.

The ecosystem is now permanently unstable and will soon collapse.

All the original species have been replaced by new ones.

An imbalance between the number of births and the number of deaths.

The organisms consciously decide to migrate to a new, more stable area.

A sudden increase in the availability of all resources for every species.

The genetic makeup of all the organisms in the population spontaneously changes.

Fish populations are not affected by floods.

The ecosystem will likely find a new balance over time.

The decrease in fish is a sign of a healthier ecosystem.

The fish will quickly adapt to live on land.
