In 'Competition' ..the interaction is detrimental ( harmful) to both the species involved...whereas in case of 'Predation' - one is benifited (predator) and the other is harmed(prey)..in case of 'Commensalism' - one is benifited and the other has no effect...and in 'Ammensalism'- one is harmed and the other has no effect..Therefore the interaction is detrimental to both the species in case of "Competition"..option D

Competition is the interaction between two or more species or individuals that requires the same resources. It is detrimental to both species because they both suffer due to the limited availability of resources. Let us understand the concept in detail:

Definition of Competition:

Competition is an interaction between two or more species or individuals that requires the same resources, such as food, space, or mates.

Examples of Competition:

1. Plants competing for sunlight, water, and nutrients in a forest.

2. Animals competing for food, water, and shelter in an ecosystem.

3. Bacteria competing for nutrients in a petri dish.

Effects of Competition on Species:

1. Reduced growth and reproduction: Competition can lead to reduced growth and reproduction of both species involved, as they have to divide the available resources.

2. Increased mortality rate: Competition can also lead to an increase in the mortality rate of both species, as they may not be able to get sufficient resources to survive.

3. Changes in behavior and morphology: Some species may change their behavior and morphology to avoid or reduce competition.

4. Evolution: Competition can lead to the evolution of new traits and adaptations that allow species to better compete for resources.

Conclusion:

Competition is detrimental to both species involved, as it leads to reduced growth, reproduction, and increased mortality rate. It also leads to changes in behavior and morphology and can drive the evolution of new traits and adaptations.
