3. In the two-kingdom classification following are drawbacks:-
- The plants comprised of photosynthetic and non-photosynthetic species.
- Fungi, that feed on dead organic matter, were placed under photosynthetic plants.
- There was another class of classification needed were the organisms with the same characteristics were clubbed into one kingdom.

Answer:
Some factors that may cause a decrease in population size:
- a high mortality rate due to an infectious disease
- a low birth rate
- a high mortality rate due to interspecific competence
- a high emigration rate
Explanation:
In biology, population size (N) refers to the total number of individuals in a given population. The four main factors that affect population size are birthrate (natality), death rate, immigration rate (i.e., the number of individuals of a given species that move into a population), and emigration rate (i.e., the number of individuals of a given species that move out of a population). Both birthrate and immigration are known to increase N, while death rate and emigration are rates known to decrease this value.
