| Biology | Ecosystem | NEET exams |
| Ecosystem | A functional unit of nature, where biotic and abiotic factors interact
Terrestrial- forest, grassland Aquatic- ponds, lake, sea |
| Primary Productivity | Biomass production rate by primary producers
Gross primary productivity (GPP)- the rate of biomass production by photosynthesis Net primary productivity (NPP)- available biomass for consumption by herbivores, it is obtained by subtracting respiratory loss from GPP |
| Decomposition | Breaking down of complex organic matter of dead and decaying remains and excreta of plant and animals into inorganic substances
Example of decomposers- bacteria, fungi |
| Photosynthetically active radiation (PAR) | The spectrum of light utilised by plants for photosynthesis
400-700 nm Accounts for ~50% of solar radiation, out of which only 2-10% is captured by plants |
| Pyramid of energy | Always upright
Only 10 percent of energy is transferred from each trophic level to the next trophic level |
| Pyramid of biomass | Mostly upright
Inverted in the sea ecosystem as the biomass of large fish is more than phytoplanktons |
| Climax community | A community, which is in equilibrium with its environment |
| Ecological succession | Gradual changes in the composition of species in a given area |
| Seral communities | Transitional communities during successive changes |
| Hydrarch succession | The succession of plants in wet areas from hydric to mesic conditions |
| Xerarch succession | The succession of plants in dry areas from xeric to mesic conditions |
| Pioneer species | Species that grow on the bare area
E.g. lichens on a rock, phytoplanktons in water |
| Standing state | Amount of nutrients present in the soil at a given time
Depends on seasons and types of ecosystems |
