The reason why Long Day Plants grow in Temperate regions is because Long Day plants flower only when the Day Length is near or greater than their Critical Photoperiod. The duration of sunshine is the stimulus that helps these plants flower only in summer/spring thereby playing a crucial role in reproduction and the continued existence of angiosperms.
Therefore Long Day Plants are an important evolutionary feature in Northern Hemisphere Temperate regions where length of day markedly varies across seasons.

u r very good in prelims…if u provide explanation and the way u guesss answers ( if any:P) everyday along with ur score would be beneficial to many upsc aspirant….humble request!

Exactly, temperate=less sunshine duration per day=short day

Then what about Eutrophication? vs Eutrophic lake? vs Oligo…?

ohhkkk ,sorry – I understand

There is a difference between Eutrophication and Eutrophic lake

For question 5 :
List of activities in ESZ[edit]
Activities which can be allowed, prohibited or regulated are broadly classified as:[7]Prohibited : Commercial mining, setting of saw mills and industries causing pollution, commercial use of firewood and major hydro-power projects, tourism activities like flying over protected areas in an aircraft or hot air balloon, and discharge of effluents and solid waste in natural water bodies or terrestrial areas.
Regulated : Felling of trees, drastic change in agriculture systems and commercial use of natural water resources including groundwater harvesting, use of polythene bags by shopkeepers, widening of roads, movement of vehicular traffic at night, introduction of exotic species and setting up of hotels and resorts are the activities regulated in the areas.
Permitted : Activities permitted in the areas include ongoing agriculture and horticulture practices by local communities, rainwater harvesting, organic farming, adoption of green technology and use of renewable energy sources.Hence..all activities given are not prohibited.
Can anyone please explain the answer??

#1. Trophic” means nutrition or growth. A eutrophic (“well-nourished”) lake has high nutrients and high plant growth. An oligotrophic lake has low nutrient concentrations and low plant growth. Mesotrophic lakes fall somewhere in between eutrophic and oligotrophic lakes.
#2. A plant that flowers only after being exposed to light periods longer than a certain critical length, as in summer. Spinach, lettuce, and some varieties of wheat are long-day plants.(In hurry I assumed this is something to do with height..got wrong) -

Long day plants—1)These bloom only when they receive more than 12 hours of light.i.e require only a short night to flower.
2)These all bloom when the days are long, during our temperate summers. Eg–California poppies, lettuce, spinach and potatoes.Short day plants—1)A plant that requires a long period of darkness, is termed a “short day” (long night) plant. Short-day plants form flowers only when day length is less than about 12 hours. If these are exposed to more than 12 hours of light per day, bloom formation does not occur. Eg–Christmas cactus.

An oligotrophic lake is a lake with low primary productivity, the result of low nutrient content. These lakes have low algal production, and consequently, often have very clear waters, with high drinking-water quality. Which means everything low
Is it not that plants requiring long day i.e short night cannot grow in temperate areas since nights are long in that region.
And hence Q5 ans becomes d
Please clarify.
-
Eutrophic lakes are having abundant supply of minerals and organic matter which lead to excessive growth of plant cover, leading to blocking of sunlight and other nutrients for other living organisms, wiping out many of the organisms and thus are poor in biodiversity.
