Multiple choice

Choose the mismatch

  1. limnology - study of fresh water ecosystem

  2. phenology - study of periodic changes in plants and animals in relation to season

  3. autoecology - study of interaction of individual organism or species with environment

  4. standing crop - amount of inorganic matters at any given time in an ecosystem

D Correct answer
Explanation

Standing crop refers to the total biomass of living organisms (plants and animals) present in an ecosystem at a given time - it's organic matter, not inorganic. Inorganic matter would refer to non-living components like minerals, water, or gases. The other definitions are correct: limnology studies freshwater, phenology studies seasonal periodic changes, and autoecology studies individual species' environmental interactions.

C Correct answer
Explanation

Hans Kelsen, founder of the Pure Theory of Law, viewed law as a 'normative science' - a system of valid norms (ought-statements) rather than descriptive facts (is-statements). Law commands behavior through hierarchical norms grounded in a basic norm (Grundnorm), distinguishing it from natural or physical sciences that describe empirical phenomena.
