This area mainly comprises of grasses with very little amount of shrubs and trees. These have very few number of trees but ferns and mosses make up fro them. It comprises aquatic fauna, flora and the properties of water too. The area between high and low tides. A closed system refers to a system where the inputs and outputs are negligible compared to the internal changes.
Figure 2 portrays a simple food chain, in which energy from the sun, captured by plant photosynthesis, flows from trophic level to trophic level via the food chain. Conifers dominate boreal forests, where their evergreen needles can photosynthesize even in winter.
Ecosystem scientists use several different tools, which can be described generally under the term "biogeochemistry". Stillwater Ecosystems Various aquatic ecosystems can be found in stagnant or very slowly flowing waters.
Lakes, ponds, bogs, freshwater and saltwater marshes, swamps and lagoons are examples of ecosystems found in stationary or nearly-stationary waters.
It was lack of this understanding in early days that led to exploitation of the natural habitats and extinction of many rare species along with destruction of some beautiful landscapes. They are broadly classified into: Usually when we think of food chains we visualize green plants, herbivores, and so on.
Sizes of ecosystems vary; they could entail a small puddle or an enormous swath of desert. The water in Marine ecosystems has salts and minerals dissolved in them in high amounts. The next question is how do we determine what the important processes or linkages are in food webs or ecosystems?
Tropical Rainforest Ecosystems Located in tropical regions, rainforests possess a greater diversity of plant and animal life than any other type of ecosystem.
These materials are transformed biochemically within the bodies of organisms, but sooner or later, due to excretion or decomposition, they are returned to an inorganic state that is, inorganic material such as carbon, nitrogen, and phosphorus, instead of those elements being bound up in organic matter.
In addition to corals and brightly-colored fish, sponges, sea anemones, sea urchins and clams make their homes in coral reefs. Element Cycling Element cycling describes where and how fast elements move in a system.
The relatively shallow part of the ocean that lies over the continental shelf. Wet, warm tropical rainforests boast the greatest diversity of plants and some of the largest trees in the world, all of them competing intensely for light in the lush forest.
The best known desert plants are the succulents like spiny leaved cacti. Processes of Ecosystems This figure with the plants, zebra, lion, and so forth, illustrates the two main ideas about how ecosystems function: Mountain ecosystems vary depending on their altitude, which influences average temperatures and precipitation; but many mountain plants and animals are adapted to withstand high winds, colder weather and steep terrain.
Arctic plants tend to be coated with hair and wax and grow low to the ground to resist wind chill. There are several main principles and tools that biogeochemists use to study earth systems.
National Geographic calls it "a bubble of life.
In a desert, succulent plants, often with thorns or other predator-discouraging adaptations, grow sparsely in the sandy soil; thorns in place of leaves also minimizes surface-area-to-volume ratios and thus minimizes water loss. Prairies can be categorized as tall grass, mixed grass and short grass prairie.
Algae, plankton, underwater and floating plants, such as lily pads, may inhabit the calm waters. Thus biogeochemistry encompasses many aspects of the abiotic and biotic world that we live in.
Likewise, natural ecosystems can look quite different from one another. Many diverse ecosystems exist on Earth -- deserts, forests, grasslands, lakes, mountains, oceans and many subcategories within those types -- and they can be identified through some basic features.
Winters and summers are well defined and with trees shedding their leaves during winter. These two processes are linked, but they are not quite the same see Figure 1. All other sub-ecosystems fall under these two.
This leads to major problems in the ecosystems as links of cycles get detached and stability of the system is lost.In ecosystem transition zones, which can be abrupt or gradual or include intermediary habitats, you will see a noticeable change in the types of plant and animal communities. Mountain ecosystems, for example, might exhibit a gradual change from tall conifers to stubby, wind-blown shrubs to a line above which trees cannot grow.
• Discuss one management practice for sustainability and conservation of natural resources in that ecosystem. • Identify the risks and benefits of extracting or using one type of nonrenewable and one type of renewable energy resource from that ecosystem, or in areas near that ecosystem.

An ecosystem is comprised of all the non-living elements and living species in a specific local environment. Components of most ecosystems include water, air, sunlight, soil, plants, microorganisms, insects and animals.Download
