Explanation:

• Inter - specific competition (b):
• The prefix "inter - " means between. When different species compete for the same resource, it is called inter - specific competition. For example, lions and hyenas competing for the same prey (a resource) in a savanna ecosystem.
• Intra - specific competition (a):
• The prefix "intra - " means within. When organisms of the same species compete for the same resource, it is intra - specific competition. For instance, male deer competing for mates (a resource) during the mating season.
• Predation (c):
• Predation is defined as the act of one organism killing another organism for food. A classic example is a wolf killing a rabbit for food.
• Predator (e):
• A predator is an organism that obtains food by killing other organisms. In the example of a fox killing a chicken, the fox is the predator.
• Prey (d):
• Prey is the organism that is killed by the predator. In the fox - chicken example, the chicken is the prey.
