Assertion: Amount of organic matter synthesized by producers per unit time and per unit area during the process of photosynthesis referred to as net primary productivity. Reason: Primary productivity is usually high and sustained throughout the year in temperate areas due to abundance of sunlight.

The temperate regions show a lower value of primary productivity as compared to tropical regions.

The biomass available for consumption to heterotrophs and the rate formation of new organic matter by consumers are defined as (a) gross primary productivity and net primary productivity respectively (b) net primary productivity and gross primary productivity respectively (c) gross primary productivity and secondary productivity respectively (d) net primary productivity and secondary productivity respectively.

Which of the following is incorrect regarding biodiversity ? I. Species diversity is highest in poles and decreases towards tropics II. Stable community shown more productivity III. Sacred groves are a type of ex situ conservation IV. More solar energy available in tropics contributes to its higher productivity .

Which of the following is a reason for the greater biological diversity of tropical regions ? (a) Tropical latitudes have remained almost undisturbed for millions of years. (b) Tropical environments are less seasonal, relatively more constant and predictable. (c) More solar energy is available in the tropics, resulting in high productivity. (d) All of these

Assertion :- Vascular cambium activity is not uniform throughout the year in temperate regions Reason :- Vascular cambium activity is under the control of many physiological and environmental factors.

Combustion of sucrose is used by aerobic organisms for providing energy for the life sustaining process. If all the capturing of energy from the reaction is done through electrical process (non P-V work), then calculate, maximum available energy which can be captured by combustion of 34.2 g of sucrose : (Given : DeltaH_("combustion")("sucrose")=-6000kJmol^(-1) DeltaS_("combustion")=180j//K-mol and bodyntemperature is 300 K)

Assertion : Tropical regions have got a long evolutionary time for species diversification as compared to temperate regions. Reason : Temperate regions have undergone frequent glaciations in the past whereas tropical regions have remained relatively undisturbed for millions of years.

In a particular region, the same fruit is available in multiple varieties, colours, with different tastes and textures. The primary reason for this could be :
