Species Interactions and Adaptations

The video explores how species interact within ecosystems, focusing on niches, competition, predation, parasitism, mutualism, commensalism, symbiosis, and coevolution. It explains how species adapt to share resources, the dynamics of predator-prey relationships, and the roles of parasitism and mutualism in ecosystems. The video also discusses how species evolve together through coevolution.

What is the primary difference between an organism's niche and its habitat?

• A niche encompasses the role and interactions of an organism within its environment.

• A habitat includes the interactions of an organism with other species.

• A habitat is the role of an organism within its ecosystem.

• A niche is the physical location where an organism lives.

Why is competition important for species survival?

• It allows species to establish territories and access resources.

• It reduces the need for species to interact with others.

• It helps species to avoid predators.

• It prevents species from adapting to their environment.

How do species adapt to minimize competition?

• By avoiding all interactions with other species.

• By sharing resources and territories to reduce direct competition.

• By eliminating other species from their environment.

• By migrating to new habitats frequently.

In a predator-prey relationship, what is a key characteristic of the predator?

• It is always larger than the prey.

• It only hunts during the day.

• It is never prey to another species.

• It feeds on another organism.

Which of the following is an example of parasitism?

• A bee pollinating a flower.

• A mistletoe extracting nutrients from a tree.

• A bird cleaning a crocodile's teeth.

• An orchid growing on a tree without harming it.

What is mutualism?

• A relationship where both species are harmed.

• A relationship where one species benefits and the other is harmed.

• A relationship where both species benefit from each other.

• A relationship where one species benefits and the other is unaffected.

Which of the following is an example of commensalism?

• A bird cleaning a crocodile's teeth.

• A lion hunting a zebra.

• A bee pollinating a flower.

• An orchid growing on a tree without affecting it.

What does the term 'coevolution' refer to?

• The process of one species evolving independently of others.

• The simultaneous evolution of two species in response to each other.

• The evolution of a species due to environmental changes.

• The evolution of a species without any interaction with others.

How does symbiosis differ from other types of species interactions?

• It only occurs between plants and animals.

• It includes interactions that are beneficial or neutral to the species involved.

• It is a temporary interaction between species.

• It always involves harm to one of the species.

Which of the following is NOT a way species interact with each other?

• Mutualism

• Isolation

• Competition

• Predation
