Which biotic and abiotic factors are different between a lion and a deer?
nevsk [136]
They are both biotic factors because they affect living organisms. The abiotic factor a lion and deer needs is water because they need to stay hydrated but water is not living . Deers eat plants, plants are known as biotic factors too. And lions eat their prey which are living animals and once they are preyed upon they are still considered biotic because they were once living before getting consumed by the lion.

Diffusion is a passive process that accounts for the movement of respiratory gases across the capillary membranes of alveoli.
strojnjashka [21]

Answer:

True

Explanation:

Diffusion is a passive process (no energy required) in which the substance such as liquid and gases moves from an area of high concentration to an area of low concentration.

During respiration, carbon dioxide diffuses from the blood into the alveoli and oxygen diffuses from alveoli to blood across the respiratory membrane. The partial pressure of oxygen is low in the blood of the pulmonary capillaries and high in the alveoli. so diffusion allow movement of oxygen across the respiratory membrane from the alveoli into the blood.

Hence, the given statement is true.
