The term Lentic ecosystems is given to standing water bodies or still water bodies. One of the interesting things about biodiversity is that it's never constant across one type of habitat. The ocean zones based on light penetration are the _____ and _____. Trophic level, step in a nutritive series, or food chain, of an ecosystem.The organisms of a chain are classified into these levels on the basis of their feeding behaviour.The first and lowest level contains the producers, green plants.The plants or their products are consumed by the second-level organisms—the herbivores, or plant eaters. Aquatic ecosystems are generally divided into two types --the marine ecosystem and the freshwater ecosystem. What role does algae play in the food chain? The well-lit upper layer of bodies of water where photosynthesis can take place is called the _____ zone. 2. Freshwater wetlands of the Moreton Bay Region and Bay islands are prominent landscape features of high biodiversity performing essential ecological functions and providing ecosystem services. •Salinity = the amount of dissolved salts contained in the water. Obviously we need freshwater to live, most of the aquatic ecosystems are marine, are not involved freshwater. •Freshwater usually has a salinity less than 7ppt. Like if you are in the upper-Amazon, that is freshwater that is flowing. C. There are four major types of organisms in aquatic systems: 1. Plankton are free-floating, weakly swimming, generally one-celled organisms. You can see most of the water we use came from surface-water sources, such as rivers and lakes.About 26 percent of water used came from groundwater. answer! The plants, animals, microbes, rocks, soil, sunlight, and water found in and around this valuable resource are all part of what is called a freshwater ecosystem. These wetlands are protected and managed under Queensland and federal legislation, international obligations and a range of laws, policies and programs administere… -flowing water. Freshwater ecosystems belong in two categories depending on the difference in water residence time and how fast the water flows.

The prominent horizontal banding of organisms that live in a particular habitat is called _____. Mutualism, commensalism, parasitism. Oceans, estuaries, coral reefs and coastal ecosystems are the various kinds of marine ecosystems.

If two organisms occupy the same niche in the same habitat at the same time, what must be true about them? A group of ecosystems that have the same climate and similar dominant communities. What type of wetland forms when a freshwater source meets the ocean? Many ecosystems blur into each other and there are not usually clear boundaries between them. Lakes and ponds are divided into three different “z… Most freshwater species of bryozoans belong to the Phylactolaemata class, while several species that tolerate brackish water belong to the Gymnolaemata class.
