Final answer:
Facilitation, inhibition, and tolerance are concepts that play a role in ecological succession. Facilitation promotes the establishment of other species, inhibition limits the growth of other species, and tolerance allows a species to persist in unfavorable conditions.
Step-by-step explanation:
Facilitation, inhibition, and tolerance are three concepts that play a role in ecological succession.
Facilitation refers to the process where one species creates conditions that make it easier for other species to establish and grow in an ecosystem. An example of facilitation in ecological succession is the presence of nitrogen-fixing bacteria on bare soil, which provide a nitrogen source for other plants.
Inhibition occurs when a species limits the establishment or growth of other species in an ecosystem. For example, some plant species release chemicals called allelochemicals that prevent the growth of other plants around them.
Tolerance is the ability of a species to withstand and persist in an environment with unfavorable conditions. Species with high tolerance can survive and reproduce in challenging conditions, such as extreme temperatures or low nutrient availability.
In summary, facilitation promotes the establishment of other species, inhibition limits the growth of other species, and tolerance allows a species to persist in unfavorable conditions during ecological succession.
