Ecology at the organismic level is essentially:
1. Physiological ecology
2. Biochemical ecology
3. Anatomical ecology
4. Pathological ecology

The biome characterized by a mean annual temperature between 0$°$C and 25$°$C and mean annual precipitation between 25 cm and 100 cm is:
1. Desert
2. Arctic and alpine tundra
3. Temperate forest
4. Grassland

Identify the biome that is not correctly matched with the physical parameters given in corresponding Column II and Column III:

The most ecologically relevant environmental factor is:

The extent of geographical distribution for eurythermals and stenothermals is expected to be:
1. Equal for both
2. Larger for the former
3. Smaller for the former
4. Cannot be predicted

If global warming continues, how would the distributional range of some species be affected?
1. There will be a poleward shift
2. There will be an equatorial shift
3. No change is expected for any species
4. There will be shift from land to marine water

The salt concentration [measured as salinity in parts per thousand] for inland waters is:
1. Less than 5
2. Between 5 and 15
3. 30 – 35
4. More than 100

Organisms that are tolerant for a wide range of salinity are called:
