Q. No.Identify the biome that is not correctly matched with the physical parameters given in corresponding Column II and Column III:
| Biome | Mean annual temperature | Mean annual precipitation [cm] | |
| 1. | Tropical forest | 20-25 | 130 - 430 |
| 2. | Arctic and alpine tundra | -12 - 2 | 10 -125 |
| 3. | Coniferous forest | -5 - 5 | 100 -200 |
| 4. | Temperate forest | 8-22 | 50 - 225 |
The four levels of biological organization to which Ecology is basically concerned are:
1. Macromolecules-tissues-populations-biome
2. Macromolecules-organisms-population-biome
3. Tissues-organs-community-biome
4. Organisms-Populations-Community-Biome
Physiological ecology
| 1. | works at the organismic level |
| 2. | Tries to understand the adaptation with respect to survival only |
| 3. | Tries to understand the adaptation with respect to reproduction only |
| 4. | None of these |
A wide variety of habitats within a biome can be a result of
1. Regional variation of temperature and precipitation.
2. Local variation of temperature and precipitation
3. Both 1 and 2
4. Natural selection
Find the odd one out about levels of biological
organization:-
1. Biome
2. Community
3. Species
4. Population
Regional and local variations within each biome lead to the formation of a wide variety of:-
1. Niche
2. Population
3. Microclimate
4. Habitat
Ecology explains us:-
| 1. | How organisms, while remaining as an individual interact with other organisms |
| 2. | How organisms, interact with physical habitats as a group |
| 3. | As a group how organisms behave like organised wholes that is population community, ecosystem or even as the whole biosphere |
| 4. | All of these |
ln the given figure, identify Coniferous forest, Arctic and Alpine Tundra and tropical forest, respectively:-
1. l, Vl and lll
2. V, Vl and lll
3. lV, lll and l
4. l, ll and lll
If '+' sign is assigned to beneficial interaction, '-' sign to detrimental and '0' sign to neutral interaction, then the population interaction represented by '+' '-' refers to
1.Mutualism
2. Amensalism
3. Commensalism
4. Parasitism
