Answer:
The living organisms must not reach equilibrium in the concentration of oxygen and carbon dioxide so that the Exchange of gases continues . Otherwise respiration and photosynthesis will stop. 
Explanation:
- Gases move along the concentration gradient i.e. from their higher concentration to lower concetration.
- If living  organisms reach a equilibrium of carbon dioxide and oxygen concentration, then The gases will not move in and out of the cells.
- This is because at state of equilibrium the concentration of gases on both side become equal and the movement completely ceases.
- If gaseous exchange in the body stops the process of respiration and photosynthesis in Plants and respiration in animal will completely stop.

Explanation:
Fungi are belongs to multicellular eukaryotic organisms. Fungi are heterotrophs in nature they can not make their own food, and they are playing very important role in nutrient cycle in an ecosystem. They can reproduce from both method sexually and asexually. They are also symbiotic associated with plants and bacteria. 
Some statements describe about the body structures or functions of fungi are:
C) Some fungi secrete digestive enzymes into the environment and then absorb the digested nutrients.
D) Mycelia are made up of small-diameter hyphae that form an interwoven mass, providing more surface area for nutrient absorption.
E) Some fungi can grow as either filamentous or single-celled forms.
F) All fungi are heterotrophs; some species live as decomposers and others as symbionts.
