If the population of rabbits in this ecosystem decreased dramatically because of certain environmental changes, which organisms' food supply would decrease? a. owl and snake b. jackal and wildcat c. green plant and mouse d. goat and wildcat

B. Jackal and wildcat

Explanation:

In a food chain the food and energy are distributed among the ecosystem when one organism is consumed by the other.  The rabbits are the primary consumers which consumes plants and their products. These can be consumed by the secondary and tertiary consumers. The jackal and wildcat are the secondary consumers. These have bigger jaw and appetite that they can consume the entire rabbit and also they may hunt for the number of rabbits in the population. But the owl and snake cannot consume the entire rabbit instead they can just feed upon their remaining parts as they have small jaw and small appetite.

not sure if this what   you'r looking for would be percent composition

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
