Answer:
The process shown in the model requires energy from the cell.
Explanation:
Active transport refers to the movement of materials across the cell membrane against concentration gradient.
The cell membrane remains intact. However, energy is required from within the cell to move materials into the cell against concentration gradient, hence the answer.
<span>The amount of energy at each trophic level decreases as itmoves through an ecosystem. ... An energy pyramid is a model that shows the flow of energy from one trophic, or feeding, levelto the next in an ecosystem. The model is a diagram that compares the energy used by organisms at each trophic level.</span>
Answer:The nitrogen present in the soil is not directly used by the bacteria. It can be used only when the nitrogen is converted into usable form. These bacteria convert atmospheric nitrogen into ammonia, then nitrite which is then converted into nitrate. This nitrate is used by the roots of the plants like soybeans and peas. This is the role of bacteria present in the roots of the plant to convert atmospheric nitrogen into usable form that can be used by plants.
