the arrows in a food chain represent how energy moves from organism to organism
option C is correct.
In a food chain, the arrows represent the flow of energy from one organism to another. The direction of the arrows shows the transfer of energy as one organism is consumed by another.
The food chain illustrates the feeding relationships between different organisms in an ecosystem, showing who eats whom and how energy is passed along the chain.
Grass (producer) → Rabbit (primary consumer) → Fox (secondary consumer)
In this example, the arrow from grass to rabbit indicates that the rabbit obtains energy by consuming the grass. Similarly, the arrow from the rabbit to the fox shows that the fox gets its energy by consuming the rabbit. The arrows represent the flow of energy through the ecosystem, as each organism transfers energy to the next link in the chain when it is consumed.

Permeability ratings for moisture in building materials. The material's resistance to moisture movement increases with decreasing perm numbers.
Building materials are said to be resistant to moisture migration through the material if their perm rating is less than 1. These function well as vapour barriers.
Building materials are thought to transmit moisture more readily from warm to cold surfaces if their perm rating is greater than 1. These are inadequate vapour barriers.
The first material type in this case is "tar paper," or wet Asphalt felt. It is employed as a sheathing wrap beneath siding and roofing. Its benefits include its moderate resistance to liquid water, ability to both absorb and store water, and high permeability when damp. Its drawbacks include its propensity for tearing and degradation when exposed to sunshine. It has a 5 perm rating. It is advised if at least 15 pounds of material is used, that it be utilised with a rain screen, and that it be an excellent alternative for all types of siding. Never rely on as an air barrier.
Plywood, the second material kind, is utilised for sheathing walls and roofs. Its structural substance, which depending on the coating absorbs and stores water, is a benefit. Its drawbacks include the possibility that it will act as a buffer by gradually absorbing and releasing moisture. It has a perm rating of 1 to 30.The majority of building does not use vapour barriers exclusively.The relative humidity of the surrounding air affects permeability.
