If the age distribution (percent individuals of a given age or age group) is plotted for population, the resulting structure is called:
(1) Survivorship curve
(2) Life table
(3) Age pyramid
(4) Logistic model
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
Calculate the birth rate of a population which has 20 individuals at time t, after one year 8 individuals have also counted along with those 20.
1. .3
2. 0.2
3. 0.4
4. 0.8

Find the odd one out about levels of biological
organization:-
1. Biome
2. Community
3. Species
4. Population
What is true for individuals of same species?
1. Live in same niche
2. Live in same habitat
3. Interbreeding
4. Live in different 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 |
1. | 10 | 2. | 9 |
3. | 25 | 4. | 15 |
The country with the given population pyramid is likely to have:
1. Low birth rate
2. High death rate
3. Declining population in future
4. More females than males
