2. Group Work Get into groups of 4 Within your groups you are to look at your homework from last night (Read pg 3 “A First or Last Chance to See”) Your group will determine from the 20 different “key pieces” of information, the FIVE MOST IMPORTANT Work together to write a paragraph of five sentences that incorporates that information You MUST write this in your own words, copying of any textbook work is an example of PLAGIARISM

3. How are we able to classify millions of different species? What role have humans played in affecting biodiversity?

4. “The variety and number of life forms on Earth (biological diversity)” -measure of ecosystem health Climate Temperature!

5. += “A group whose members are able to freely breed among themselves under natural conditions” + = INFERTILE

6. Morphology animals vs. plants asexual reproduction (fungi, plants, micro-organisms) MORPHOLOGY “the physical appearance and characteristics of an organism” Genes

7. Individual Variability - individuals found within the same species can show differences in their morphology 1. Over Time and Space Evolutionary change: a change that occurs in an entire population (over LONG period of time) physical and behavioural what causes? 2. Biodiversity Genetic diversity: the genetic variability among organisms (same species) sexual reproduction unique offspring

8. Species DiversityandHabitat Diversity Combination of different species and physical environment they inhabit Heterotrophs and autotrophs takes into account the quantity of each species as well as the variety of species present The larger and more diverse, the healthier/stable the ecosystem species interactions? monoculture vs. polyculture

9. Species Interactions Complete the chart in your notes using Tbl 1: Species Interactions on pg. 11 InteractionDefinitionExample

10. Species DiversityandHabitat Diversity Combination of different species and physical environment they inhabit Heterotrophs and autotrophs takes into account the quantity of each species as well as the variety of species present The larger and more diverse, the healthier/stable the ecosystem species interactions? Structural diversity: the range of physical shapes and sizes within a habitat of ecosystem monoculture vs. polyculture

11. Greater structural diversity  greater species diversity  greater biodiversity

12. List the four bullet points regarding the effect loss of biodiversity will have on humans (pg. 12) Effects of extinctions? Natural Human
