(Ch. 12‚ Section “How Are Marine Organisms Classified?”) Plankton Plankton is a organism that float. Why is a copepod‚ which can swim and propel itself through the water‚ classified as plankton? (Ch. 12‚ Section “Plankton”) Because of its small size‚ it cannot swim very far or fast so its location

Chapter 27. BACTERIA & ARCHEA Overview: Prokaryotes thrive almost everywhere‚ including places too acidic‚ salty‚ cold‚ or hot for most other organisms Masters of Adaptation Most prokaryotes are microscopic‚ but what they lack in size they make up for in numbers There are more in a handful of fertile soil than the number of people who have ever lived They have an astonishing genetic diversity Prokaryotes are divided into two domains: bacteria and archaea Structural‚ functional‚ and genetic

Preliminary Biology Assessment task 2013 A Local Ecosystem Mangrove Swamp Cassandra Mandelik Introduction: A mangrove is a tree‚ shrub‚ palm or ground fern‚ generally exceeding the height of one and a half metres. They normally grow above mean (average) sea level in intertidal zones of marine coastal environments as well as estuarine margins. A mangrove also refers to the tidal habitat comprising of such trees and shrubs. Australian mangrove systems are highly effecting by human presence
