FAQs on Introduction to Organisms & Populations Video Lecture - Biology Class 12 - NEET
| 1. What is the difference between an organism and a population? |  |
Ans. An organism refers to an individual living being, such as a plant, animal, or human, while a population refers to a group of organisms of the same species living in a particular area at a given time.
| 2. How do organisms interact within a population? | |
Ans. Organisms within a population interact in various ways. They compete for resources like food, water, and shelter. They also mate and reproduce, leading to the growth of the population. Additionally, they may exhibit social behaviors, such as cooperation or territoriality.
| 3. What factors influence the size of a population? | |
Ans. Several factors can influence the size of a population. These include the availability of resources, predation, disease, competition, environmental conditions (such as temperature and rainfall), and the presence of limiting factors like space or nutrients.
| 4. How is population growth determined? | |
Ans. Population growth is determined by the difference between birth rate and death rate within a population. If the birth rate exceeds the death rate, the population will increase. Conversely, if the death rate exceeds the birth rate, the population will decrease.
| 5. What are the different patterns of population distribution? | |
Ans. The patterns of population distribution include clumped, uniform, and random distribution. Clumped distribution occurs when individuals cluster together in groups, uniform distribution happens when individuals are evenly spaced, and random distribution occurs when individuals are dispersed randomly throughout an area. These patterns can be influenced by factors like resource availability, social behavior, and environmental conditions.
