Which is an abiotic factor that affects a freshwater ecosystem apex?

My guess is that fat-soluble toxins that may occur in freshwater ecosystems would most affect apex species in these ecosystems. This is because fat-soluble toxins are stored in the fat reserves of animals, and then bioaccumulate up the food chain. So in this case, most of the toxin is not secreted, but stored within the food chain, and bioaccumulates, with the concentration becoming higher the further up the food chain.

Sonbull [250]

Answer:

In mammals, oxygen is carried through the red blood cells called hemoglobin. The reason is that the oxygen is very important for the cell for releasing energy. This energy is used by the cell in different processes.

2) These adaptations are adapted by the organisms in order to perform different functions. In slow twitch skeletal muscles having high number of mitochondria because it requires more energy while fast twitch skeletal muscles contains less amount of mitochondria due to low requirements of energy. These characteristics are adapted according to the performance of the body parts.
