the effects of tsunamis‚ rebuild homes and physical infrastructure‚ and regain economic stability. Oftentimes disasters and subsequent recovery processes reveal complex inter-relationships and dependencies. For example‚ seawater over inland areas due to a tsunami increases salinity of soils and can render land unsuitable for cultivation. If arable land is reduced‚ food supply is diminished and farmers must seek other employment‚ which dramatically affects their livelihoods. Tsunami risks can be mitigated

rate in Daphnia magna increases when there is a progressive lack of oxygen present. (Baumer et.al 2002). When the salinity of water increases there are increases in Na+ ions as well as Cl- ions. This increase in ion concentration causes a change in osmotic alternation and a competition between all the ions. (de la Paz Gomez-Diaz and Martinez-Jeronimo 2008). Although increase in salinity has been known to be detrimental to the health of the Daphnia magna‚ if high enough can result in mortality‚ Daphnia

Chapter 7: Living in the Environment: environmental factors and their influence Questions Introduction 1. Why is a Polar bear found living in a cold icy place and a fish found living in water‚ but not in other environments? Because it is their habitat in which they are adapted to. It has certain adaptations to allow it to survive in that environment and resources are available in the environment. 2. Give the definitions for the following words (the glossary at the back of the book may help

in growing in salty coastlines‚ less than a meter above sea level. This is made possible because their leaves are covered by hairs that minimize water loss. Their environment contains steep gradients‚ that has fairly mild salinity around the terrestrial borders but the salinity becomes severe in salt pans and water logged areas (Richards‚ C‚ Pennings‚ S. & Donovan‚ L 2005). One of the benefits of Batis maritima is the role it plays in the regeneration of degraded mangrove forests. This plant
