much of the oxygen present in the Earth’s atmosphere – half of the total amount produced by all plant life.[3] Their cumulative energy fixation in carbon compounds (primary production) is the basis for the vast majority of oceanic and also many freshwater food webs (chemosynthesis is a notable exception). Since the 20th century‚ phytoplankton has declined by roughly 1% yearly‚ possibly linked to warming oceanic temperatures - as of 2010 this means a decline of 40% relative to

SOME BASIC TIPS ON HOW TO WRITE A LAB REPORT Just searching on line will give you hundreds of examples so I just want to keep this really simple and basic and if you want to or need more explanation‚ just search the specific heading like “ How to write a conclusion on a lab report” and you will get more info than you ever wanted!

The Science and Impacts of Climate Change on the Maldives Science of global warming and climate change Anthropogenicly produced greenhouse gases has exacerbated global warming. The burning of fossil fuels and deforestation have resulted in almost doubling the amount of CO2 in the atmosphere. The concentration of CO2 has increased at a rate of 2.0 ppm/yr.‚ which is much faster than in pre-industrial times (1). This greenhouse gas absorbs long wave radiation heat emanated away from the earth which

ecosystem. An aquatic ecosystem is an ecosystem located in a body of water. Communities of organisms that are dependent on each other and on their environment live in aquatic ecosystems. The two main types of aquatic ecosystems are marine ecosystems and freshwater ecosystems. What is an aquatic ecosystem? Aquatic systems are those that contain plants and animals that predominantly depend on a significant amount of water to be present for at least part of the year. But a perfect definition is tough to make

The Ganga Project Introduction “Throwing her head in a swirl of ice spray‚ in pride and defiance creeping round lovingly some favoured rock to rush down joyously over the boulders hurling herself with a mighty shout over some great precipice…smiling and dancing in the morning sunlight and dark and gloomy and full of mysteries in the evening shadow‚ a narrow‚ slow and graceful stream in the winter‚ vast and roaring during the monsoon.”- Jawaharlal Nehru.

less than 1mm in size and because of that‚ they can’t be removed from the ocean. In recent studies‚ researchers discovered that Zooplankton are able to digest these (“Plankton”). Normally‚ when they defecate‚ without digesting the plastic‚ they travel to the bottom of the ocean floor and build up to strengthen the nutrients on the bottom floor. However‚ when Zooplankton digest plastic‚ since it’s less dense than what they normally eat‚ it takes longer time to travel so the feces will most likely

Chesapeake bay is having problems with recent algal blooms. This paper will discuss the roles of the organisms in the partial chesapeake bay food chain‚ The possible effects of a decrease in the algae population on the plant and animal populations‚ What the causes of this problem is‚ what is being done to fix it‚ and what else could be done. Algae is a floating plant on top of the water; that is at the bottom of the food chain. This plant has no roots‚ and floats freely about the water. According

impact on the interdependent biosphere because biodiversity is directly intertwined with the nonliving components of the Earth (Mittermeier et al. 2002). Aquatic ecosystems have a large biodiversity of species such as phytoplankton‚ cyanobacteria‚ zooplankton‚ insects‚ fish‚ birds‚ and mammals (Reece et al. 2010). Each species makes a unique contribution to the function of the ecosystem‚ and adding or removing species from an ecosystem can have a measurable impact unless lost contributions can be offset
