Ecological Interactions and Competition

The video explains ecological interactions within a community, focusing on intraspecific and interspecific interactions. Intraspecific interactions occur within the same species, such as competition for resources. Interspecific interactions occur between different species, including competition and predator-prey relationships. The video also discusses the nature of these interactions, which can be positive, negative, or neutral, providing examples like mutualism and competition.

What is a biological community composed of?

• Only animals and fungi

• Various species in a common location

• A single species in a location

• Only plants and trees

How are ecological interactions classified?

• Into positive and negative

• Into specific and non-specific

• Into intraspecific and interspecific

• Into mutual and competitive

Which of the following is an example of intraspecific competition?

• Foxes and rabbits in a predator-prey relationship

• Lions and leopards competing for prey

• Fish cleaning parasites off sharks

• Plants competing for sunlight

What is an example of interspecific competition?

• Hummingbirds competing for nectar

• Male deer competing for mates

• Different species of trees competing for light

• Rabbits and deer living in the same area

What is a characteristic of predator-prey relationships?

• They are a type of mutualism

• They are always neutral

• They cause population fluctuations

• They only occur in rainforests

How can you remember the difference between interspecific and intraspecific interactions?

• Intraspecific is between different species

• Interspecific is like international, between different species

• Intraspecific is like international, between different species

• Interspecific is within the same species

What is mutualism?

• A positive interaction where both species benefit

• A neutral interaction

• A negative interaction

• An interaction where one species is harmed

Which interaction is considered negative?

• Predator-prey relationship

• Mutualism

• Competition for resources

• Neutral coexistence

What is an example of a neutral interaction?

• Plants competing for sunlight

• Rabbits and deer living in the same woodland

• Fish cleaning parasites off sharks

• Lions and leopards competing for prey

What should you understand from the video about interactions?

• Intraspecific interactions are always positive

• Interspecific interactions are always negative

• Interactions can be positive, negative, or neutral

• Only positive interactions exist
