ECOLOGY Ecology is concerned with the study of organisms and their habitats. This includes the interdependence of various populations‚ their impact on each other and their surroundings‚ the effect of the surroundings on their behaviour‚ as well as the ways in which the organisms and the environment change in response to each other. A pond and its inhabitants provide a good example of these interrelationships. A pond contains: a. soil consisting of rock‚ minerals and dead remains of organisms b. water

Aquatic Biome! ! The aquatic biome makes up the largest part of the biosphere‚ covering nearly 75% of the Earth’s surface and consists of the freshwater biome and the marine biome. Freshwater regions consist of ponds‚ lakes‚ streams‚ rivers‚ wetlands and marine regions include oceans‚ coral reefs and estuaries. Marine biomes generally have salt concentrations that average 3%‚ whereas freshwater biomes are usually characterised by a salt concentration of less than 0.1%. The aquatic biome is probably

Lakes: standing bodies of water range from ponds a few square meters in area to lakes covering thousands of square kilometers. Temperature lakes may have a seasonal thermocline; tropical lowland lakes have a thermocline year-round. Salinity‚ oxygen concentration‚ and nutrient content differ greatly among lakes and can vary with season. Wetlands: habitat that is inundates by water at least some of the time and that supports plants adapted to water-saturated soil. Some wetlands are inundated at all

They exists in two forms namely microphytes and macrophytes. Microphytes include

Aquatic Biomes An aquatic biome is an ecological community dominated by water. This biome can be broken down into two categories: o Freshwater‚ which includes rivers‚ streams‚ ponds‚ lakes and freshwater wetland. o Marine or saltwater‚ which includes oceans‚ seas‚ estuaries‚ coral reefs and saltwater wetland. Each of these aquatic ecosystems can be defined by variables such as temperature‚ the presence or absence of light‚ and the availability of nutrients. Aquatic biomes cover almost all the

Aquatic ecosystem An estuary mouth and coastal waters‚ part of an aquatic 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

There are many different types of invertebrates such as crayfish‚ clams‚ snails‚ leeches and other aquatic insect that play a key role in keep the aquatic ecosystems healthy. Throughout time aquatic invertebrates have morphologically adapted the different environments to benefit their everyday survival
