Answer:
B. Competition for light and moisture
Explanation:
Plants grow towards sunlight which is necessary for photosynthesis, of which they utilize sunlight, carbondioxide, and moisture to manufacture their food. In the tropical rain forest, competition is intense among plants for sunlight and moisture.
The trees/plants that are able to get enough sunlight and moisture gain advantage over others as they grow bigger and taller, as the rest struggle to get some sunlight and moisture. The canopy of taller trees usually cut-off sunlight from teaching shorter trees, thereby making availability of sunlight to the shorter trees quite limited. As a result of this, we have variations of trees with different height in the tropical rainforest.

Saturated fatty acids are 'saturated' with hydrogen meaning they contain the maximum number of hydrogen. This causes them to be straight on the molecular level, allowing them to be packed close together other saturated fatty acids. Thus, they tend to be solids at room temperature. Examples of saturated fats are butter and the solid white fat you see on raw meat.
