Interactions in an ecosystem occur between organisms and themselves, and organisms and the environment. These interactions are important for the health of the ecosystem. Ecosystems are a collection of all the living things, called biotic factors, and nonliving things, called abiotic factors in an are...
Organisms accumulate heavy metals and metalloids from their surroundings to a greater or lesser extent (Bowen 1966) and may acquire undesirably high levels of such elements as a result of pollution or other conditions conducive to bio-accumulation (Hg in aquatic ecosystems being a particularly ...
* Energy Flow Through Ecosystems An ecosystem must have a continuous input of energy(sunlight) to retain its stability. The energy stored in the molecules of producers is transferred to other organisms when the producers are eaten. Each step in the flow of energy through an ecosystem is known ...

components from which functioning ecosystems are composed (cf. ref.28). Diverse interactions occur not only between species but indirectly through the effects that species have on the abiotic environment29,30,31. Elephants root out large saplings and small trees, enabling the formation and ...
The allelopathy (mutual interactions between the organisms through the excretion of matters in to the environment) plays an important role in forest ecosystems. We have observed various tree-tree allelopathic interactions in middle European Forests during the different development phases of trees. We hav...
Actions and Interactions of Soil Invertebrates and Arbuscular Mycorrhizal Fungi in Affecting the Structure of Plant Communities Soil invertebrates and arbuscular mycorrhizal (AM) fungi co-occur in all ecosystems of the world. However, the interactions between these organisms are rar... AC Gange,VK Bro...
