What is Competition?

Competition is a type of population interaction between individuals or species where both entities strive for the same limited resources, such as food, shelter, or mates. It is a critical force driving natural selection and shaping the structure of communities and ecosystems. The struggle for survival and access to essential resources has profound implications for the distribution and abundance of species....

Examples of Competition

A few examples of Ecological Competition are as follows:...

Types of Competition in an Ecosystem

The various types of ecological competition are given below:...

Competitive Exclusion Principle

The Gauss Exclusion Principle was proposed by G. Evelyn Hutchinson and it specifies one of the major effects of competition. The Competitive Exclusion Principle, also known as Gause’s Law, states that two species competing for the same limited resources cannot coexist indefinitely in the same ecological niche. This means, if two species have identical ecological requirements and directly compete for the same resources, one of the species will eventually outcompete and exclude the other species from that particular niche....

How to Avoid Competition?

Organisms have evolved various strategies to avoid competition and ensure their survival. Let’s understand these strategies in detail....

Conclusion – Competition Notes Class-12

In conclusion, competition interaction is due to limited resources like food, water, and space. It plays a crucial role in shaping ecosystems and influencing natural selection. Through competition, organisms develop strategies for resource acquisition and survival, leading to adaptations that enhance their competitive abilities. Understanding the various types of competition and the Competitive Exclusion Principle helps learn species diversity and distribution in natural ecosystems. Moreover, organisms have evolved strategies such as niche specialization, spatial and temporal segregation, adaptive behaviors, and resource partitioning to avoid direct competition and ensure their survival, further highlighting the complex interplay of species interactions in ecological systems....
