How do adaptations help Ann organism to reduce competition for food and other resourses

Gre4nikov [31]

An organism adapting to its environment leads it to be more ‘equipped’ for survival.
Competition is when other species fight for the same resources that another species needs. Also, it would produce offspring with these adaptations.

An example (to help you better understand);

A blue jay has great eyesight, strong wings, and sharp beak. (Better adapted organism) Another blue jay has great eyesight, weak wings, and dull beak. (The competitor/unadapted)

Both birds find the same food source and are now competing for it. The first bird has sharp beams, which is better for breaking, and ‘chomping’ the seeds/food. The second bird would struggle to consume its food (seed) unless it’s worms.

So which one is better adapted? The first blue jay.

And i hope this helped show how competition can be reduced.

Explanation: In medicine, the practitioners divide the lower part of the body known as the 'abdomen' with imaginary lines ( one vertical and one horizontal) to form the 'Quadrants' and (two vertical and two horizontal) the 'Regions'. The Quadrants are divided into four main parts:

1) Left Upper Quadrant (LUQ)

2) Right Upper Quadrant (RUQ)

3) Left Lower Quadrant (LLQ)

4) Right Lower Quadrant (RLQ)

The regions are divided into nine parts:

1) Left Hypochondriac Region

2) Right Hypochondriac Region

3) Epigastric Region

4) Left Lumbar Region

5) Right Lumbar Region

6) Umbilical Region

7) Right Iliac/Inguinal Region

8) Left Iliac/Inguinal Region

9) Hypogastric Region.

The abdomen is divided into regions in order to help medical practitioners and students easily understand the abdominal area of the body as well as the human anatomy. It also helps them provide preliminary diagnosis and treatment based on pain emanating from each region or quadrant.
