Ecological Relationships and Interactions

This video tutorial explores the various ecological relationships within ecosystems, including symbiotic relationships like mutualism, commensalism, and parasitism, as well as non-symbiotic relationships such as competition and predation. It highlights how these interactions affect population dynamics and ecosystem balance.

What do ecological relationships primarily describe?

• The chemical composition of soil

• The geological features of an ecosystem

• The interactions between organisms and their environment

• The weather patterns in an ecosystem

In mutualism, how do both species benefit?

• One species is unaffected

• Both species benefit from each other's actions

• Both species compete for resources

• One species is harmed while the other benefits

Which of the following is an example of commensalism?

• A bee pollinating a flower

• A tapeworm in a cow's intestine

• An orchid growing on a tree

• A lion hunting a zebra

In parasitism, what is the role of the host?

• To remain unaffected

• To provide resources to the parasite

• To benefit from the parasite

• To compete with the parasite

Which of the following is a characteristic of non-symbiotic relationships?

• Organisms live closely together

• Organisms live apart from each other

• Both organisms benefit equally

• One organism is always harmed

What is intra-specific competition?

• Competition between different species

• Competition for mates

• Competition within the same species

• Competition for sunlight

Which of the following is an example of predation?

• A tapeworm absorbing nutrients

• A tree providing shade to an orchid

• A snake eating a frog

• A bee collecting nectar

What role does the predator play in a predation relationship?

• It is consumed by the prey

• It provides nutrients to the prey

• It hunts and consumes the prey

• It remains unaffected by the prey

How do carnivorous animals obtain their nutrients?

• By consuming plants

• By decomposing organic matter

• By absorbing sunlight

• By eating other animals

What is the primary outcome of ecological interactions in an environment?

• To disrupt the ecosystem balance

• To maintain a balanced ecosystem

• To increase the number of predators

• To decrease the number of prey
