A healthy ecosystem is self-sustaining and resilient. It is balanced, stable and maintains the organisation and function over time. Further... View Article
An ecosystem is influenced by both biotic and abiotic factors. Human intervention also influences ecosystems. Biotic factors include plants, animals,... View Article
A micro-ecosystem is a small-scale ecosystem, which is a subset of the biotic community and environmental factors of a larger... View Article
There are various factors that cause a change in the ecosystem. These include changes in climate, habitat, invasive species, pollution,... View Article
The term ‘ecosystem’ was coined by Arthur Tansley in 1935. An ecosystem is the functional unit of the biosphere, which... View Article
Overpopulation has many negative effects on an ecosystem. It increases the demand for food and habitat which leads to deforestation,... View Article
In an ecosystem, primary productivity refers to the accumulation of energy in terms of biomass. In aquatic ecosystems, coral reefs... View Article
Yes, energy is conserved in an ecosystem. Energy flows in the ecosystem from one trophic level to another. Photosynthetic plants... View Article
Human interventions influence the cycling of matter in an ecosystem. E.g. burning of fossil fuels and deforestation have caused disruption... View Article
