Answer: when a nature or human caused disturbance disrupts the nature balance of an ecosystem. if a species disappears or a new species is introduced it can become a threat to ecological balance..
What is a balance ecosystem?
Ecological balance is a term describing how ecosystems are organized in a state of stability where species coexist with other species and with their environment. Ecosystems are not without change, however. Disturbances can occur, although an ecosystem typically recovers back to a state of ecological balance.
What maintains the balance of the ecosystem?
A balanced ecosystem works via energy and material cycling. The chief energy source of ecosystems is sunlight. Photosynthesis of sunlight by plants creates oxygen as a waste product, which in turn is used in respiration by animals. Animals, in turn, create carbon dioxide as waste, and that is used by plants.
What are the factors affecting ecological balance?
Degradation of Land and Soil Erosion 2. Deforestation 3. Faulty Utilisation of Water Resources 4. Environmental Problems from Faulty Mining Practices 5.
What is the biggest threat to ecosystems?
Climate change was ranked as a 6% risk to Earth’s biodiversity. WWF’s Living Planet Report 2020 has ranked the biggest threats to Earth’s biodiversity. The list includes climate change, changes in land and sea use and pollution. The WWF used data from over 4,000 different species.

What is the effect of pollution on ecological balance?
Air pollution affects ecosystems in a number of ways, altering basic ecosystem functions such as primary production (plant growth) and biogeochemical cycling which in turn affect the ecosystem services and therefore the benefits that humans get from the environment such as timber, clean drinking water and an …
How ecological balance is disturbed by natural disaster?
Earthquakes, landslides, volcanic eruptions and natural bush fires all affect the many different ecosystems on our planet. Initially, these disasters negatively affect the biodiversity of wetlands, forests and coastal systems by causing the spread of invasive species, mass species mortality and loss of habitat.
How man is disturbing the ecological balance?
Ecological balance is disturbed by humans in several ways. Cutting of trees, hunting of animals, wastage of water and pollution are the major ways in which humans disturb the ecological balance. EXPLANATION: Ecological balance refers to a stable balance in the number of every species in the ecosystem.
