Unit 2

Question 1

What are the three types of biodiversity?

Answer 1

1. Ecosystem Diversity: The diversity of habitats an ecosystem has
2. Species Diversity: The amount of different species that exist in an ecosystem.
3. Gene Diversity: For a given population (group of the same species), how diverse the genepool is.

Question 2

What are the two types of species diversity?

Answer 2

• Species Richness: How many species
• Species eveness: How even the populations of the species are spread out

Question 3

Why is biodiversity important?

Answer 3

The amount of diversity in an exosystem allows it to be more resilient to population-disrupting events.

Question 4

Define:

Bottleneck Event

Answer 4

An event that disrupts an ecosystem by eliminating a large amount of the population

Question 5

Why are bottleneck events important?

Answer 5

When a population dereases by a lot, so does the biodiversity. Even though the population will increase, the biodiversity is still lower which does makes the environment less resistent.

Question 6

Define:

Inbreeding Depression

Answer 6

When organisms are reproducing with organisms that are very closely related to each other leading to genetic defects

Question 7

Phylogenetics

Answer 7

Phylogenetics is the study of the evolutionary relationships between organisms, based on their genetic material revealed through DNA and RNA sequencing.
