Species Competition and Resource Management

The video discusses competition in population interactions, focusing on inter-specific and intra-specific competition. It explains interference competition with examples like flamingos and fishes, and provides historical evidence from the Galapagos Islands. The concept of competitive release is illustrated through Cornell's experiment with barnacles. Gause's competitive exclusion principle is discussed, highlighting that closely related species cannot coexist indefinitely. Resource partitioning is explained as a mechanism for coexistence, with examples of different foraging times among species. The video concludes with a call to action to subscribe.

What is the primary factor that determines the winner in a competition between two species?

• The color of the species

• The size of the species

• The fitness of the species

• The speed of the species

Which type of competition occurs between individuals of the same species?

• Inter-specific competition

• Intra-specific competition

• Interference competition

• Competitive exclusion

What is an example of competition between unrelated species?

• Lions and tigers

• Flamingos and fishes

• Eagles and hawks

• Wolves and foxes

What is interference competition?

• Competition where species avoid each other

• Competition where species share resources

• Competition where one species interferes with another's habitat

• Competition where species cooperate

What happened to the tortoise population on the Galapagos Islands when goats were introduced?

• The tortoise population decreased

• The tortoise population remained stable

• The tortoise population increased

• The tortoise population migrated

What is competitive release?

• When a species is introduced to a new habitat

• When a superior competitor is removed, allowing an inferior species to thrive

• When two species share resources equally

• When a species evolves to become a superior competitor

In Cornell's experiment, what happened when the superior competitor was removed?

• The habitat was destroyed

• The superior species returned

• The inferior species flourished

• The inferior species declined

According to Gause's competitive exclusion principle, what happens to two closely related species competing for the same resource?

• They coexist peacefully

• They merge into one species

• They both thrive equally

• One is eventually eliminated

What is resource partitioning?

• Eliminating the inferior species

• Competing for the same resources

• Avoiding competition by using resources at different times

• Sharing resources equally

How do the five closely related species of warbler birds avoid competition?

• By eating different types of food

• By living in different trees

• By having different foraging activities

• By migrating to different areas
