The definition of ecosystem is a system that is formed by a community of organisms interacting with their environment. Both living and nonliving things within a particular area make up the ecosystem.
In nature, ecosystems can range in size from small ponds or a tree to larger areas like a desert. Everything in that area, from water and soil to animals and plants, make up an ecosystem. Even climate, light and air play important roles. If there is not enough light or the right nutrients in the soil to support plant life, the plants can die. This can cause a chain reaction that kills animals and destroys the ecosystem.
Natural disasters, changes in climate and human interactions can cause problems in an ecosystem. Because of this, healthy ecosystems are home to many different species. This helps protect the ecosystem from significant damage in the event something bad happens.
Ecosystems are formed of producers, consumers and decomposers. Producers, like green plants, make their own food. This allows animals to eat the plants to get their energy and other animals to get energy from eating other consumers. Decomposers are the plants and animals that help break down other plants and animals when they die. This helps to put nutrients into the soil that help future generations of plants to grow and start the cycle over.Learn More
The five kingdoms of living things are Monera, Protista, Fungi (or Mycota), Plantae (or Metaphyta) and Animalia (or Metazoa). The kingdom is the third taxonomic rank in the biological classification system.Full Answer >
The phospholipid bilayer's function is to maintain a barrier between the cell and its external environment and to store and transport a variety of proteins that are essential to the cell's function. It controls what enters and exits the cell.Full Answer >
Fungi are structured in filaments called hyphae, which are made up strings of cells and separated from one another by septa or crosswalls. Many of these hyphae grouped together make up mycelium.Full Answer >
The process of breathing performs a number of important gas exchanges through inhalation and exhalation. When someone inhales, they contract and move their diaphragm, which allows the lungs to expand. This is a part of the process needed to psychically suck in the air. When a person exhales, the diaphragm relaxes and the movement is undone. This allows air to be gradually pushed out of the lungs.Full Answer >
