Biodiversity and Ecosystem Health Concepts

The video discusses biodiversity, which is the variety of life in an area, determined by the number of species. It explains how biodiversity contributes to the health of ecosystems, using a business analogy to illustrate adaptability. The video breaks down biodiversity into three types: genetic, species, and ecosystem diversity. Genetic diversity involves the variety of genes within a species, enhancing survival chances. Species diversity refers to the number and abundance of species in a community, while ecosystem diversity is the variation of ecosystems in a region. The video concludes by emphasizing the importance of these diversities for ecosystem health.

What is biodiversity primarily concerned with?

• The number of ecosystems in a region

• The temperature variations in an area

• The variety of life in an area

• The amount of rainfall in a region

How does biodiversity relate to the health of an ecosystem?

• It only affects the health of marine ecosystems

• It increases the health of an ecosystem

• It has no effect on ecosystem health

• It decreases the health of an ecosystem

In the business analogy, what does having a variety of shirts represent?

• Focusing on a niche market

• Having a single product line

• Adapting to market changes

• Ignoring customer preferences

What is genetic diversity?

• The number of ecosystems in a region

• The number of species in a community

• The variety of genes in a population

• The amount of rainfall in an area

Why is genetic diversity important for species survival?

• It only affects plant species

• It has no impact on survival

• It decreases the chance of survival

• It increases the chance of survival

What does species diversity refer to?

• The number of genes in a species

• The amount of sunlight in an area

• The number of species and their abundance

• The number of ecosystems in a region

How does species diversity affect ecosystem health?

• It decreases ecosystem health

• It only affects aquatic ecosystems

• It has no effect on ecosystem health

• It increases ecosystem health

What is ecosystem diversity?

• The number of genes in a population

• The variation in ecosystems in a region

• The variety of species in a community

• The amount of rainfall in an area

Which regions typically have high ecosystem diversity?

• Deserts

• Polar regions

• Rainforests

• Urban areas

What is the relationship between biodiversity and ecosystem health?

• As biodiversity increases, ecosystem health increases

• Biodiversity has no impact on ecosystem health

• Biodiversity only affects terrestrial ecosystems

• As biodiversity increases, ecosystem health decreases
