COMPETITION Competition is the process by which living organisms in the habitat struggle with one another for limited essential needs in the environment. Such scarce resources in plants include; light, space, nutrient and water while animals complete for food, space or mate. Competition finally results in survival of the fittest and elimination of the unfit.   Types of competition Intraspecies competition: competition between organisms of the same species. e.g. many maize seedlings grown in a small area. Interspecies competition: that between different species of organisms. e.g. many maize and pepper seedlings growing in a small area.   Relationship between competition and succession Succession is the change in a population caused by the replacement of the old members with new ones as a result of competition. The newly formed habitat is gradually colonized by different species of plants in a stepwise manner until a relatively stable community is established and later… Read More »ADAPTATION FOR SURVIVAL
