In a study aquatic ecologists counted the number of species in equal volumes of water Where would you expect them to find the smallest number of species?
When comparing population sizes of similar sized species why are aquatic species more abundant than terrestrial?
There are two reasons why aquatic species can be more abundant than terrestrial species. First of all, the majority of the surface of the Earth is covered in water. There is more water than dry land. Secondly, aquatic species don't just live on the surface of the water, they have the volume of the water to live in, while terrestrial species mostly live on the surface (even though there is a certain amount of burrowing)…
All aquatic nuisance species are deliberate or accidentally introductions into Washington from what sources?
Minute rootless aquatic herbs having globular fronds floating on or near the water surface and bearing one flower per frond. Species of the genus Wolffia are the smallest flowering plants. Commonly called watermeal, these aquatic plants resemble specks of cornmeal floating on the water. Source: Answers.com
Ecologists are people who study how the organisms interact with each other and their environments. Now you may think how does math play a role in the environment...? BUT it does: To find out how many extinct, exotic, endangered species are in a given area ecologists have to calculate the biomass of food chains. Biomass includes numbers. Hence, math is used in ecology by ecologists! :P
