Answer:
takes substances captured from the external environment (air and carbon sources) and converts them into energy for building more cells and tissues and for carrying out life-sustaining activities. It also generates waste products and water.

Answer:
Option-C
Explanation:
The organisms of the Fungi form the symbiotic relationship with the plants by living in their roots. This symbiotic relationship is known as the mycorrhizal association which provide phosphorus to the plant.
The research on the correlation between the fungal species and plant diversity shows that the fungal species help increase diversity. The fungi form the hyphae structures which connect one plant with another plant and increases their communication level and distribute the phosphorus nutrients in the plants. This help increases the diversity of the plants.
Thus, Option-C is correct.
The meaning of the scarce is insufficient for demands.
The scarcity of the food is determined by the availability of the food in the market. In case, the food available in the refrigerator is easily available in the nearby stores, then it is not scarce. In case, the food available in the refrigerator is not readily available in the market, then it is scarce.
Answer:
The return of blood to the heart is assisted by the action of the skeletal- muscle pump. As muscles move, they squeeze the veins running through them. Veins contain a series of one-way valves, and they are squeezed, blood is pushed through the valves, which then close to prevent backflow.
I'm no sure but I think this a factor of evaluation, so an evolutionary explanation?
