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.Continue Reading
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 about Biology
Eukarya is a classification of living things that includes organisms such as the protists, fungi, plants and animals. Organisms are divided into three domains: Archaea, Bacteria and Eukarya. Domain Eukarya consists of eukaryotic organisms, which are organisms that have cells containing membrane-bound structures called organelles.Full Answer >
In the trophic structure, classification of organisms in an ecosystem occurs through the energy source and consumption of food by an organism. The trophic structure represents the relationship between species and food sources.Full Answer >
Biotic factors of a pond include all living organisms that make up the pond ecosystem. The biotic factors can be split into different trophic levels, such as autotrophs, heterotrophs, and saprotrophs, depending on their function in the ecosystem.Full Answer >
Biotic factors are living organisms affecting a particular ecosystem and their relationships. Fish, frogs, water plants, bacteria and insects are biotic factors in a river habitat.Full Answer >
