<span>The 4 categories of macromolecules include carbohydrates, proteins, lipids, and nucleic acids. Carbohydrates (grains and vegetables) are the largest group at the base of the pyramid, proteins (milk, poultry, eggs, nuts) follow up the pyramid while lipids (fats and oils) are the least amount at the summit of the pyramid. </span>

</span><span>The aim of the pyramid is to recommend ideal rations for a healthy diet. Carbohydrates provide most of the energy needs for the days’ activities hence taking the largest portion. Proteins are used in building muscles, f0r nutrition, and body’s immunity hence required in lesser amounts compared to carbohydrates. Lipids help the body store energy since they have thrice as much energy as carbohydrates.They also a constituent of cell membranes and also help deliver vitamins. They are required in the least amount to avoid obesity and related illnesses such as cardiovascular <span>diseases</span></span>

Answer:
Dandelions may appear <u>quicker after harsh conditions and reproduce at a faster rate.</u> However, both dandelions and shrubs are considered <u>fast-growing plant species</u> that can be categorized as <u>pioneer species.</u>
Explanation:
Secondary succession refers to the changes that take place in a disturbed habitat. Pioneer plant species are those that <u>colonize new habitats after harsh climate conditions and that tend to reproduce at a fast rate.</u>
According to researcher J.W. Darlling (2008), pioneer herbs and shrubs are species that tend to grow faster in comparison to other species, making them excellent pioneer species.
This occurs thanks to plants that are <u>wind-pollinated</u>, such as dandelions, have a higher chance to appear because, as it is a disturbed environment, there are no insects or other fauna present. In addition, shrubs are <u>persistent species that are able to reproduce fast with limited soil availability</u> but a bit <em>slower</em> in comparison to dandelions.
