Answer:
According to the law of conservation of matter, matter is never created or destroyed but it can change from one form to another. Most of the biomass in a food web gets converted at each trophic level and it no longer remains apart of the food web. Most of the biomass is released into the atmosphere in the form of heat and hence cannot be transferred to the other trophic level. Also, matter is used up by the organism itself and converted into different forms. Most of the matter might get accumulated in the soil when the organisms of a trophic level die.
It's G, since plants need carbon dioxide to perform photosynthesis
Answer:
When the terminal (third) phosphate is cut loose, ATP becomes ADP (Adenosine diphosphate; di= two), and the stored energy is released for some biological process to utilize.
I think this is because peptide hormones are made in advance and stored in secretory vesicles while steroid hormones are synthesized on demand on precursors, thus the response of peptide hormones will be more rapid. Additionally the receptors for peptides are on the cell membrane while those for steroid hormones are located on cytoplasm or nucleus, some have receptors on the membrane also.
