What is an Ecosystem?
Many of the ecosystems are threatened due to pollution, global warming and anthropogenic causes.
Energy Flow in the Ecosystem
Energy flow in the ecosystem is the amount of energy that moves in a food chain. Energy entering is measured in calories, hence also called Calorific Flow.
Types of Ecosystem
There are basically two types of ecosystems- Terrestrial & Aquatic, all other ecosystems fall under one of the these types.
What is an Ecotone?
Ecotones are of great environmental importance, it’s a transition zone and contains a variety of flora and fauna influenced by both ecosystems.
What is an ecological succession?
It is a process by which communities of an ecosystem change in a defined and directional way over time.
Types of Terrestrial Ecosystems in India
Terrestrial Ecosystems provide many services including- providing habitat for flora and fauna , fibre, fuel, shelter, storing ,transforming and releasing carbon, water and nutrients.
Significance of Aquatic Ecosystem
Aquatic ecosystem perform many important environmental functions.For example- recycling nutrients, purify water, attenuate floods, recharge water and provide habitats for wildlife.
Types of Aquatic Zones
Life in aquatic zone is influenced by temperature, access to sunlight for photosynthesis, dissolved oxygen and availability of nutrients.
Types of Forests of India
Forests play an important role in the socio-economic development of a country like India.They are rich sources of energy, housing, firewood, timber and fodder and they provide employment to a large section of rural population.
Procedure of Assessing Environment Impact
Environment Impact Assessment is the assessment of the environmental consequences of a plan, policy program or actual projects prior to the decision to move forward with proposed action.
Process of Bio-Accumulation & Bio-magnification
Example of bio-magnification- a small fish eating plankton tainted with mercury.. the toxin amplifies as it moves up the food -chain
Significance of Mangroves
Mangroves protect shorelines from damaging by storms, hurricane winds, waves and floods.Mangroves help to prevent erosion ,maintain water quality and clarity by filtering sediments.
