Class Activity II-MW1230

What is the tolerance level of an organism?

• The maximum limit beyond which an organism cannot survive

• The environmental conditions within which an organism can survive and function

• The minimum limit below which an organism cannot survive

What are indicator species?

• Species that are not affected by changes in their environment.

• Species that are used as an indicator of an ecosystem's overall health or condition.

• Species that are selected based on their ability to adapt to new environments.

What is the ecological niche of a species?

• The role that the species plays in its environment

• The number of individuals in a species' population

• The size of a species' habitat

What is the main difference between generalist and specialist species?

• Generalist species are more vulnerable to predators or diseases.

• Specialist species have a broad ecological niche.

• Specialist species are adapted to specific environmental conditions or resources.

What are endemic species?

• Species that are found worldwide.

• Species that are found in specific geographic locations and nowhere else naturally.

• Species that are found in isolated mountain ranges only.

   

What is the Competitive Exclusion Principle?

• Two species that compete for the same limited resources can coexist indefinitely.

• Two species that occupy the same niche in a particular environment will eventually coexist without directly competing with each other.

• Two species that compete for the same limited resources cannot coexist indefinitely.

What is the process by which one species splits into two or more distinct species?

• Genetic drift

• Natural selection

• Speciation

Why is species diversity important?

• It provides benefits for human well-being such as food and medicine.

•   It can lead to greater stability and resilience of ecosystems.

•  Both a) and b).

Which species interaction is essential in regulating populations?

• Competition

• Predation

• Commensalism

What is mutualism in species interactions?

• When two or more species use the same resources in the same place at the same time.

• A positive interaction between two species that benefits each of them.

• An interaction between two species in which one species benefits while the other is neither helped nor harmed.
