Lichens are ecologically important because

  1. They are associated with mycorrhizal roots.

  2. They are association of algae and fungi.

  3. They are pioneers (earliest settlers on barren rocks) and pass xeric conditions successfully.

  4. They can grow in greatly polluted area.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Lichens are known as pioneer species, these can survive in places where higher plants finds it difficult to grow. Irrespective of the type of region, extremes in environmental conditions, mountainous terrains and high latitudes, lichens are good survivors. Besides these, the major ecological importance of the lichens are that these are poikilohydric. With little control over the status of hydration, these are able to tolerate irregular and even severe dessication. Thus, the correct answer is option C.

Suggest some approaches towards the conservation of forests.

  1. Conversion of forests into national parks, sanctuaries

  2. To take help of local people in conserving forest

  3. Both A and B

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Forests and wildlife are the natural resources which maintain ecological balance and biodiversity in the ecosystem. The forest provides shelter and food to the different species and thus need to be conserved because if the forests are not conserved, then it may affect these habitats with the extinction of species. Without proper management of forest and wildlife, the quality of soil, the water sources, and even the amount of rainfall may be affected. Without forest and wildlife, life would become impossible for human beings.

Some approaches towards the conservation of forests are:
→ Conversion of forests into national parks, sanctuaries. 
→ To take help of local people in the conserving forest. 
→ Not to allow the destruction of forests for making roads, dams and hotels etc. 
→ Planting of trees should be increased.

  3. Sympatric species

  4. Endemic species
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Endemic species are ecological populations that are restricted to a specific, defined geographical location and found nowhere else on Earth. Ecospecies, allopatric species, and sympatric species refer to different evolutionary or taxonomic categories rather than restricted distribution alone.

What is Red Data Book?

  1. Red coloured book

  2. Book that maintains an international list of all endangered animal and plant species

  3. Book that maintains an international list of all endangered animal species

  4. All of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The Red Data Book is a list of endangered species. It is released by ICUN (The International Union for Conservation of Nature). It was first released in 1963.

A Red Data Book contains lists of species whose continued existence is threatened. Species are classified into different categories of perceived risk. Each Red Data Book usually deals with a specific group of animals or plants (reptiles, insects, mosses). They are now being published in many different countries and provide useful information on the threat status of the species. 
The red-listing assessment is a simple logical process to determine the status of the threat to a species based on available information.
