energy flow

ability to do work

PAR means

light with wavelengths between 400 and 700 nm that is used by plants for photosynthesis

plants and other organisms use this to convert light energy into chemical energy

crucial for climate processes because it absorbs carbon dioxide from the atmosphere and subsequently binds it in plants, soils, and harvested goods.

components of energy flow in ecosystem

provides the majority of the energy used by people. it is also the source of biomass, fossil fuels, and some renewable energies like wind and solar electricity

what percentage of sunlight reach the Earth’s atmosphere and reflected back

__% of sunlight is held by ozone layer, water vapor, and other atmospheric gases

__% reaches the Earth’s surface and out of that 2 of 10% is used by plants and the remaining is absorbed as heat by water

organisms that use sunlight to generate their own energy

they convert sunlight, water, and carbon dioxide into sugar, which is then used to make food

producers in terrestrial ecosystem

producers in aquatic system

animals that depends on plants for their food needs

consumers are also called

they are unable to manufacture their own food. they eat plants or other animals for energy

degrade dead organic matter or detritus

decomposers are also known as

they derive their energy, carbon, and nutrients from organic substrates for growth and development

it include energy transformation which occur within the ecosystem

study of energy flow within an ecological system from the time it enters the living system until it is degraded to heat and irreversibly lost from the system.

ecological energetics is also called

ecological energetics studies ….
