A population is the number of a species living in a particular area
For food, water and space
Predators will eat prey and reduce the population (including the number of offspring)
Members of the population may leave the area
A disease could kill some of the population
Drought, fire, floods, volcanic eruptions etc could alter the habitat and affect the population
Wars can result in the death of many members of a population
How well are individuals adapted?
This will affect their survival in a habitat.
What else lives there? This may mean competition for food.
There may be predators.
Adaptation describes how a plant of animal is able to survive in various environments
Well adapted organisms can cope with the different aspects of their environment, for example, the temperature
ANIMALS STRUGGLE :
For protection against weather
Against being eaten by predators
For minerals in the soil
Against being eaten
Well adapted organisms are better at coping with extremes of weather
They are better at competing for food
They are better at escaping from predators
They are more likely to survive in their habitat and produce offspring
This sort of habitat can have extremely low temperatures
The ground is covered with white snow for most of the year
