Describe in detail how the different niches occupied by three organisms in a habitat mean that organisms can co-exist.

sergey [27]

A niche is like a role in the environment. All the niches work together to create a diverse ecosystem. So if there is 3 organisms occupying 3 different niches in their ecosystem, they will have different roles to keep their ecosystem flourishing. These 3 organisms will also not compete with each other, which means that they will co-exist.

The absorption of this mineral is decreased when the diet is high in fiber and phytates.

Gekata [30.6K]

The absorption of iron is reduced when you have a diet high in fiber and phytates. Even though an excess of fiber can have an effect in the body’s ability to absorb some minerals, fiber is very safe and even necessary in reasonable amounts. phytatic acids on the other hand are responsible of binding metallic cations reducing the capacity of the body of absorbing iron, calcium and zinc and should be consumed with moderation.

This holds an organism's hereditary information. All cells contain the same genetic information before differentiation.

umka2103 [35]

DNA or deoxyribonucleic acid is macromolecule composed of nucleotides (nitrogen nucleobase, deoxyribose sugar and phosphate group) which carries genetic information (instructions). Instructions within DNA are for development, growth, reproduction and many other functional roles of an organism.

All of the cells within an organism contain the same genome (full set of DNA-chromosomes). When cells begin the process of differentiation (cells become specified) their genome stays the same, but the gene expression is different (different genes are on or off).
