Answer:
B) aposematic coloration
Explanation:
The species constantly compete between each other, some because they occupy the same niche int he food chain, others even though they are in different niches tend to destroy each other, and some just avoid each other and partition the resources. This often results in partitioning of the resources between different species, when usually they are active in different parts of the day and avoid each other. Also, it is common that some of the species is more competitive, so that will result in a decline of the other species, or if the species are on the same level of competitiveness, then usually both species have declines in numbers to some optimal level. The aposematic coloration though is not part of the competition between the species. It is a type of coloration that warns the other species that the species that possesses it is either not good for eating, or it has a weapon that can harm them, thus they should avoid it and leave it alone.

When hydrogen combine with oxygen, water is formed. According to law of conservation of matter, matter cannot be created nor destroyed during a chemical reaction. So according to this law, the amount of reactants is equal to the amount of product produced after a chemical reaction and the number of oxygen atoms is the same before and after the reaction.
