Archaeologists have given at least five different explanations about why and how complex societies arose. Please briefly describe and name one of those explanations and provide a name of a culture or region from the lectures or your readings that fits the theory.

You scoop up a water sample from a local pond nearby, becauseyou are curious about the possible microbes that might live there.After looking at several slides that held drops of the sample, younoticed two different kinds of cells: One kind was very small andhad no separate internal structures; the other kind was muchlarger, and it contained several kinds of internal structures thatwere physically different from each other. Please name each celland briefly describe their overall similarities anddifferences.

DRAFT WRITING

Introduction and first body paragraph

I. Introduction

Possible ideas for the introduction

Climate change

Process of OA

Somehow lead to SO

Thesis Statement : All organisms living bathed in an acidic environment will incur a metabolic cost as a result of the energy expended to maintain functioning cell chemistry this results in reduced growth and reproductive outputs. As a consequence population numbers will drop with a flow on reduction in overall ecosystem biomass and diversity.

-

II. Body

-

Main Point: OA has a metabolic cost for all marine organisms and affects growth, reproduction and nutrient value as a food source.[CA2]

Examples/Details/Explanations (include references (author, date)) :

Most pronounced in small organisms but is variable and dependant on pH

e.g. krill, gill & haemolymph regulation issues (Flores et al, 2012) ;

e.g. phytoplankton, reduced nutritional value;

e.g. shell forming organisms dissolution of CaCO3 shells e.g. pteropods

-

Main Point: The metabolic cost on the individual results in lower numbers of individuals in a population.

Examples/Details/Explanations (include references (author, date)):

This cost results in reduced fertilisation, extended larval development time, deformities

e.g. seastar (Gonzalez-Bernat et al, 2014) detail effects at different pH levels;

e.g. urchin (Sewell et al 2014)

-

Main Point: A reduction in biomass of any one species has flow on effects up and down the food chain and could be especially pronounced in the unique Southern Ocean ecosystem.

Examples/Details/Explanations (include references (author, date)):

SO characterised by high nutrient low productivity, ‘wasp-waist’ structure and short food chains

e.g. phytoplankton as primary producers

e.g. krill as important food source

e.g. pteropods as nutrient cyclers

-

Main Point: Reduced food availability will likely alter interspecific interactions and may result in some species being driven to extinction.

Examples/Details/Explanations (include references (author, date)):

a. competition will increase as a result of less food e.g. between larger birds and mammals as a flow on from loss of krill

b. shell forming species will be at greater risk of predation due to weaker shells

c. e.g. seastars as keystone species maintaining diversity

-

III. Conclusion

Effects at organism level will impact on total biomass of that species and those that depend on it for food, therefore the overall productivity and biomass of the SO ecosystem will be reduced and loss of species diversity is expected.

-

Other Ideas to Conclude:

Effects growth and reproduction and is especially costly for shell forming organisms.

Will see changes as a result of effects on organisms with key functions within the SO ecosystem.

-

Ideas to leave the reader with (clincher):

Global significance of effects of OA on SO (something related to carbon sink and sequestering of Carbon) or perhaps reminding reader that OA is only one consequence of climate change and that organisms will also be at risk from rising sea temps, melting ice, and invasive species.
