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.
More pesticide-resistant insects. just like bacteria and viruses, insects are growing immunity's to pesticides thus stronger pesticides are needed. <span />
Answer:
DNA polymerase is an enzyme that synthesizes DNA molecules from deoxyribonucleotides, the building blocks of DNA. These enzymes are essential for DNA replication and usually work in pairs to create two identical DNA strands from a single original DNA molecule.
Explanation:
Answer:
a. Lower
b. Stimulates
In negative geotropism of shoots, auxin is redistributed to the lower side of the cell, where the amyloplasts have accumulated, where it stimulates cell elongation.
Explanation:
Geotropism can be defined as the direction the various parts of a plant grows toward due to the stimulus which in this case is the force of gravity. Geotropism in plants can be negative or positive.
Negative geotropism occurs when the shoots of a plant grows upwards against the force of gravity.
