Dear student 
Struggle for Existence. There is an inevitable competition between the organisms for space, food, shelter, nesting sites, water, etc. This struggle takes place in three ways-
 
a) Intraspecific struggle
 
b) Interspecific struggle and
 
c) Environment struggle
 
a) Intraspecific struggle takes place between the individuals of the same species. This is often most severe and fatal, as the needs of the individuals of the same species are similar.
 
b) Interspecific struggle takes place between the individuals of different species. In a community, some organisms feed on others. Both animals and plants are affected by this kind of struggle.
 
c) Environmental struggle is the struggle of organisms against the physical environment. Organisms struggle against excess of moisture, drought, extreme heat or cold, lightning, volcanic eruptions, etc.
