Biodiversity

Question 1

Why is maintaining biodiversity important for maintaining ecosystems?

Answer 1

species depend upon each other in the food chain

in regions of reduced biodiversity, connections may not be present which eventually harms all species

Question 2

What areas have the most biodiversity?

Answer 2

warm areas, highest near equator (generally)

Question 3

What is habitat biodiversity?

Answer 3

refers to the number of different habitats found within an area

each habitat can support a number of different species

in general, the greater the habitat biodiversity the greater the species biodiversity

Question 4

What are the two types of species biodiversity?

Answer 4

species richness - number of different species living in a particular area

species evenness - a comparison of individuals of each species living in a community, abundance of all species, how close the numbers of each species are

Question 5

What is genetic biodiversity?

Answer 5

refers to the variety of genes that make up a species

Question 6

Why is important to consider richness and eveness when assessing biodiversity?

Answer 6

reveal dominance of a species

high biodiversity is associated with high species richness and eveness
