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.

Ice caps form because high-latitude regions receive less energy in the form of solar radiation from the Sun than equatorial regions, resulting in lower surface temperatures.

Why does DNA need to replicate before cells divide?
gizmo_the_mogwai [7]
DNA needs to replicate before cells divide to give the complete set of genetic instructions to its daughter cells, (or ensures that each new cell inherits all of the genetic traits of the parent cell). 

Hope this helps! :D
