Ecological Interactions Unveiled in Ecosystems

The video tutorial by Teacher Fyng introduces the concept of ecological relationships within ecosystems. It covers five main types: mutualism, commensalism, parasitism, predation, and competition, providing examples for each. The lesson aims to help learners understand how organisms interact with each other and their environment. It concludes with a summary, review questions, and an application task for students to identify ecological relationships in their community.

What is the main purpose of organisms interacting with each other in an ecosystem?

• To avoid predators

• To establish territories

• To obtain food and energy

• To migrate to new areas

Which of the following is an example of mutualism?

• A bee pollinating a flower

• A shark and a remora

• A lion hunting a zebra

• A mosquito biting a human

In commensalism, how is the second organism affected?

• It is unaffected

• It is killed

• It benefits

• It is harmed

What type of relationship exists when one organism benefits and the other is harmed?

• Competition

• Mutualism

• Commensalism

• Parasitism

Which relationship involves a predator and its prey?

• Predation

• Mutualism

• Commensalism

• Parasitism

What happens in a competitive relationship?

• Organisms share resources

• Both organisms are harmed

• Organisms compete for the same resources

• One organism benefits, the other is unaffected

Which ecological relationship is characterized by one organism being killed?

• Mutualism

• Commensalism

• Predation

• Parasitism

What is the outcome when two species try to occupy the same niche?

• Commensalism

• Mutualism

• Parasitism

• Competition

What might happen if organisms do not interact with their environment?

• They will become predators

• They will migrate

• Some may die of hunger

• They will have plenty of food

How can you apply your understanding of ecological relationships in your community?

• By feeding all animals

• By ignoring local wildlife

• By identifying and describing local ecological relationships

• By avoiding all interactions with nature
