Mutualism- both species helped Commensalism- one species helped; one species not affected Parasitism- one species "parasite" helped; one species "host" harmed
Mutualism: It is the biological interaction between two organisms in which both the organism gets benefit from each other. For example- butterflies take nectar from the plant's flower and spread the pollen to the next flower. So both the individuals gets the benefit from each other.
Commensalism: It is the interaction between two organisms in which one individual is benefitted and other is not harmed not benefitted. For example, remora fish attaches to the body of big fishes to travel so it gets benefitted and big fishes are neither harmed not benefitted by this interaction.
Parasitism:In parasitism, one individual is harmed and another is benefitted. For example, tapeworm is a parasite that gets its nutrition from its host and host gets weaker because of lack of nutrients. So tapeworm is benefitted and the host is harmed.
the surrounding ecosystem is nearly or completely destroyed this changes the physical and biological components of the system by killing any biological life and reshaping all structures with magma. this will affect the population by killing anything living haunting life for centuries until new life can start to form such as lichens to break down the hardened rocks nutrients into soil for life
