Answer:
The relationships include symbiosis, predation and competition.
Explanation:
Organisms relate with each other in different ways in the environment. Such relationships include:
Competition: This deals with the struggle between organisms for food and other available resources. The strongest and fittest usually have a higher chance of survival.
Predation: This is the process by which bigger animals prey on smaller animals for food. This helps in movement of energy in the trophic levels and also the balancing of the eco system.
Symbiosis: This is a mutual relationship in which two organisms form a type of partnership and benefit positively from each other.
