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:-

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
