The energy pyramid is always upright because energy is lost as heat at each trophic level, making energy transfer inefficient.
Ref: NCERT Class 12 Biology Chapter 12: Ecosystem Ecosystem Services and Functions
Zooplankton are consumers that feed on phytoplankton, which are primary producers.
Ref: NCERT Class 12 Biology Chapter 12: Ecosystem Ecosystem Services and Functions
Higher biodiversity contributes to ecosystem stability by ensuring functional redundancy and resilience to disturbances.
Ref: NCERT Class 12 Biology Chapter 12: Ecosystem Ecosystem Services and Functions
Primary producers, such as plants and phytoplankton, convert inorganic substances into organic material through photosynthesis.
Ref: NCERT Class 12 Biology Chapter 12: Ecosystem Ecosystem Services and Functions
Denitrification is the microbial process that converts nitrates back into nitrogen gas, returning it to the atmosphere.
Ref: NCERT Class 12 Biology Chapter 12: Ecosystem Ecosystem Services and Functions
According to the 10% Law, only 10% of the energy from one trophic level is transferred to the next, while the rest is lost as heat.
Ref: NCERT Class 12 Biology Chapter 12: Ecosystem Ecosystem Services and Functions
Decomposers release nitrogen from dead organisms and organic matter into the soil, making it available for plants.
Ref: NCERT Class 12 Biology Chapter 12: Ecosystem Ecosystem Services and Functions
Phytoplankton are primary producers in aquatic ecosystems, performing photosynthesis to produce energy.
Ref: NCERT Class 12 Biology Chapter 12: Ecosystem Ecosystem Services and Functions
A frog is a secondary consumer as it feeds on primary consumers like insects.
Ref: NCERT Class 12 Biology Chapter 12: Ecosystem Ecosystem Services and Functions
Tertiary consumers occupy the highest trophic level and receive the least energy due to energy loss at each transfer.
Ref: NCERT Class 12 Biology Chapter 12: Ecosystem Ecosystem Services and Functions
Carnivores do not belong to the second trophic level; they are secondary or tertiary consumers.
Ref: NCERT Class 12 Biology Chapter 12: Ecosystem Ecosystem Services and Functions
Grasshoppers are herbivores, not detritivores. Detritivores, such as earthworms, fungi, and bacteria, decompose dead organic matter.
