Competition and Resource Management in Ecology

The video tutorial explores the concept of competition in ecology, highlighting its role as a negative interaction where species compete for resources. It discusses Darwin's theory of natural selection, emphasizing competition's role in evolution. The tutorial explains interference competition, where species presence affects others' feeding efficiency, and competitive exclusion, where superior species eliminate others. It also covers competitive release, where species expand when competitors are removed, and resource partitioning, allowing coexistence through different resource usage strategies.

What is the primary outcome of competition according to Charles Darwin's theory of natural selection?

• All species coexist peacefully.

• Both species benefit equally.

• The fittest organism survives.

• Resources become unlimited.

In the context of competition, what is interference competition?

• When unrelated species never compete.

• When resources are abundant and competition ceases.

• When one species' presence reduces another's feeding efficiency.

• When species share resources equally.

What is an example of unrelated species competing for the same resource?

• Birds and insects feeding on different plants.

• Lions and tigers sharing a habitat.

• Deer and rabbits grazing together.

• Flamingos and fishes competing for zooplankton.

What is an example of competitive exclusion in nature?

• A species expanding its range when a competitor is removed.

• Two species sharing the same habitat indefinitely.

• A species becoming extinct due to the introduction of a new species.

• All species coexisting without any competition.

What does the competitive exclusion principle state?

• Competition only occurs among herbivores.

• Two closely related species competing for the same resources cannot coexist indefinitely.

• All species can coexist if resources are abundant.

• Two unrelated species can coexist indefinitely.

What is competitive release?

• When a species' range is restricted due to a superior competitor.

• When a species expands its range after a competitor is removed.

• When competition leads to extinction.

• When two species share resources equally.

How do warblers avoid competition while living in the same tree?

• By migrating to different trees.

• By feeding on different types of food.

• By choosing different times for feeding.

• By eliminating other species.

What is resource partitioning?

• The sharing of resources equally by all species.

• The elimination of one species by another.

• The complete avoidance of competition.

• The division of resources among competing species.

Which group is more adversely affected by competition according to the transcript?

• Insects

• Carnivores

• Herbivores and plants

• Omnivores

What happens when resources are not limiting according to recent studies?

• Competition always leads to exclusion.

• Species may evolve mechanisms to promote coexistence.

• All species become extinct.

• Competition ceases entirely.
