Match each biodiversity restoration method to its description we have:
- reforestation: using plants to absorb harmful compounds
- biological augmentation: using plants to control a native plant population
- bioremediation:using plants to increase biodiversity and food resources
<h3>What are ecological restoration techniques?</h3>
Some examples of induced ecological restoration methodologies are the conduction of natural regeneration, nucleation techniques, enrichment or diversity planting, among others.
In this case, the ecological restoration techniques are:
- reforestation: using plants to absorb harmful compounds
- biological augmentation: using plants to control a native plant population
- bioremediation: using plants to increase biodiversity and food resources

The correct answer is a theory.
A theory is a rational and contemplative kind of generalizing or abstract thinking or the outcomes of such thinking. On the basis of the context, the outcomes might involve generalized illustrations of how nature functions.
A theory can be a source of knowledge that may or may not is related to the specific explanatory models. To theorize is to create the body of knowledge.
