FACTORS AFFECTING A POPULATION
In ecology, the interaction between plant and animals in an environment produces a stable and a balance system. A population is referred to as stable if the population size remains relatively constant.
There are many factors that contribute to the balance in nature; these factors are either abiotic or biotic
1. Abiotic factors these factors are:
(a) Availability of space
(b) Light
(c) Heat
(d) Oxygen (air)
(e) Water
(f) Food
2. Biotic factors: these factors are
(a) Predation
(b) Competition
(c) Parasitism
(d) Diseases
(e) Natality
(f) Mortality
(g) Territorial behaviour
(h) Dispersal
EVALUATION
- List five factors (abiotic ) that contribute to the balance in nature.
- List five factors (biotic) that contribute to the balance in nature.
DYNAMIC EQUILIBRIUM
The biotic community in each ecosystem is composed of population of many species.
