Which of the following best describes how the chemical energy travels up the food pyramid?
A. Chemical energy is used by each of the
organisms in the food pyramid, resulting in less
energy as it moves up the pyramid.
B. Chemical energy is made by each of the
organisms in the food pyramid, resulting in more
energy as it moves up the pyramid.
C. Chemical energy is not needed by the
organisms in the food pyramid, resulting in equal
amounts of energy throughout the food pyramid.
D. Chemical energy is used by producers but
created by consumers, resulting in fluctuations
in the amounts of energy throughout the food
pyramid.

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.  

correct answer: understand the different control methods available

integrated pest management is an strategy that is based on the ecosystem and try to prevent the pest and the damage caused by them by applying combination of technique like habitat manipulation, biological control and use of resistant varieties.

the main aim of the integrated pest management is not to completely eliminate the pest but to strengthen the ecosystem so that conditions are favorable for plants and unfavorable for pests.
