When a secondary consumer ingests a primary consumer, only some of that energy is stored in the secondary consumer. the rest is: a) Stored in the primary consumer b) If the organism is not completely consumed, then it can't all be stored, so some of the energy is left behind, c) Lost into space or d) Converted to heat and movement energy

because they are eaten by the frog and the frog getseaten by the snake and the snake by the eagle

i think it’s c but i might be wrong. if i am let me know! have a good rest of your day as well!

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
