Biodiversity and Conservation Concepts

The video explains biodiversity, focusing on species richness and evenness, and how these concepts apply to different ecosystems. It highlights the importance of biodiversity for human well-being, providing ecosystem services like flood control and pollination. The video also discusses the need for conservation efforts to protect habitats and prevent species extinction.

Which forest is considered more diverse based on species evenness?

• Both are equally diverse

• Forest B

• Neither is diverse

• Forest A

What does species richness refer to?

• The genetic variation within a species

• The number of ecosystems in an area

• The abundance of a single species

• The number of different species

How is species evenness determined?

• By counting the total number of species

• By evaluating the number of ecosystems

• By assessing the relative abundance of each species

• By measuring the genetic diversity

What is genetic diversity?

• The number of different species in an area

• The variety of genes within a population

• The number of ecosystems in a region

• The abundance of a single species

Why is ecosystem diversity important?

• It increases the number of species in an area

• It provides more resources for human and wildlife use

• It limits the spread of invasive species

• It reduces the need for conservation efforts

How does biodiversity contribute to human well-being?

• By providing medicines and building supplies

• By reducing the number of species

• By decreasing ecosystem services

• By limiting genetic diversity

What role does biodiversity play in economic activities?

• It limits the availability of natural materials

• It increases the cost of production

• It has no impact on the economy

• It provides essential resources for industries

What is the leading cause of species extinction today?

• Habitat loss

• Overpopulation

• Genetic diversity

• Ecosystem diversity

Why is it important to protect habitats?

• To reduce the number of ecosystems

• To ensure the survival of wildlife

• To limit genetic diversity

• To increase the number of invasive species

What is a key conservation effort to maintain biodiversity?

• Limiting genetic diversity

• Protecting intact wild ecosystems

• Increasing urban development

• Reducing the number of species
