Los aminoácidos químicamente son sustancias que estan formadas como su nombre lo indica, por un grupo amino y uno carboxilo, unidos ambos a un carbono central. Recordemos que el átomo de carbono tiene valencia 4, es decir, tiene cuatro lugares para sostener enlaces. Por lo tanto el resto los puede ocupar con átomos de hidrógeno u otras cadenas carbonadas a las que simbolizamos con la letra R. R puede ser un grupo metilo o un etilo o un gruo de más carbonos o también un anillo aromático, etc

In a rainforest food chain, caterpillars and butterflies eat orchid plants. Toucans eat the caterpillars and butterflies. Leopar
Tems11 [23]

Answer:

The caterpillars gain energy directly from the orchids

Explanation:

Earth maintains the flow of nutrients in the form of cycles and linear sequence in which the nutrients in the form of matter and energy flows from one organism to another and one sphere to another sphere.

One such flow of nutrients in the form of matter and energy can be observed in the organisms when one organism feed upon another and gain energy. This flow of matter and energy is called a food chain.  

The energy flows in this food chain through ten percent rule which states that only ten percent of energy can be transferred to next trophic level, therefore, the organism at the lowest level will have the highest amount of energy.

In the given question, the caterpillars can be considered as primary consumers which gain energy from the orchid plants directly and thus is the most appropriate answer.
