Answer:
Unlike matter, as energy flows through an ecosystem in one direction, from photosynthetic organisms to herbivores to omnivores and carnivores and decomposers, less and less energy becomes available to support life.
Explanation:
Primary producers use energy from the sun to produce their own food in the form of glucose, and then primary producers are eaten by primary consumers who are in turn eaten by secondary consumers, and so on, so that energy flows from one trophic level, or level of the food chain, to the next.
Energy is acquired by living things in three ways: photosynthesis, chemosynthesis, and the consumption and digestion of other living or previously-living organisms by heterotrophs.
Living organisms would not be able to assemble macromolecules (proteins, lipids, nucleic acids, and complex carbohydrates) from their monomeric subunits without a constant energy input.
Answer:
DNA → mRNA → tRNA → Protein
DNA → mRNA → tRNA → Protein
Explanation:
This is because during protein synthesis, DNA is use to make RNA in the process called transcription. The DNA double strand is unwind by an enzyme called RNA polymerase to produce mRNA in the nucleus. The trans is produced in the nucleolus by RNA polymerase 1 and the site then binds aminoacyl tRNAs which is assembled in the RIBOSOMES. The tRNA are then translated into protein.
Answer:
plants For example, phototropism is the plant's response to stimulus, i.e. sunlight. A plant hormone “auxin” keeps the plant's direction towards the sun by activating the growth in a particular part of a stem. Similarly, gravitropism in plants responds to the stimulus, i.e. gravity
