Answer:
Animal migration is the relatively long-distance movement of individual animals, usually on a seasonal basis. It is the most common form of migration in ecology. It is found in all major animal groups, including birds, mammals, fish, reptiles, Many of these migrations are north-south, with species feeding and breeding in.
The five major attributes of populations that help ecologists predict population growth or decline are -
1. Population size- This describes the total population in the area. It helps to ascertain if there is any need for population protection or any need for breeding.
2. Population density- It determines that large organisms live in less populated density places whereas it is easy to find groups and mates in a high populated places.
3. Population distribution- A population may have a uniform, random, or clumped distribution pattern
4. Sex ratio- It depicts the number of males to number of females. This will determine if the population will increase or decrease in the near future.
5. Age structure- defines the relative numbers of organisms in each age group. This indicates whether population will grow or shrink overtime.
