Mutualism, Competition, and Adaptation in Ecology

The video explores species interactions within ecosystems, focusing on competition, predation, and symbiosis. It explains how species compete for resources, the dynamics of predator-prey relationships, and the different forms of symbiosis, including parasitism, mutualism, and commensalism. These interactions are crucial for understanding resource use and population dynamics in ecosystems.

What is the primary reason for competition among species in a habitat?

• Predator presence

• Limited resources

• Symbiotic relationships

• Abundance of resources

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

• Predatory competition

• Symbiotic competition

• Intraspecific competition

• Interspecific competition

What does the competitive exclusion principle state?

• Two species can coexist indefinitely in the same niche.

• Predators will always exclude prey from a habitat.

• Species will always share resources equally.

• One species will outcompete another for the same resource.

How do certain warblers avoid competition for resources?

• By migrating to different areas

• By feeding at different times

• By using different parts of the same resource

• By changing their diet completely

In a predator-prey interaction, what typically happens to predator numbers when prey numbers increase?

• Predator numbers remain constant

• Predator numbers fluctuate randomly

• Predator numbers increase

• Predator numbers decrease

What adaptation might a prey species develop to avoid predators?

• Increased size

• Camouflage

• Loud noises

• Bright coloration

What is the defining characteristic of a parasitic relationship?

• Both species are harmed

• Both species benefit

• One species benefits, the other is unaffected

• One species benefits, the other is harmed

In mutualism, how do both species benefit?

• Both species are unaffected

• One species is harmed, the other benefits

• Both species compete for the same resource

• One species provides food, the other provides shelter

Which of the following is an example of commensalism?

• A tick feeding on a dog

• A bird cleaning a rhino

• A bromeliad growing on a tree

• A lion hunting a zebra

How does an egret benefit from following a buffalo?

• It uses the buffalo for transportation

• It gains warmth from the buffalo

• It finds food more easily

• It gets protection from predators
