The movement of nutrients into the vascular stele requires energy, unlike the movement of water that does not require energy. This energy is provided by the phloem. Sugars are produced in the leafs, as part of the photosynthesis process, so whenever a new root is growing, or a fruit needs to grow, the phloem gets in action. With the help of the water the sugars get in the phloem, which can most simply be seen as an elevator inside the plant, that is moving nutrients up and down, on the places in which they are most needed.
Answer:
The cow uses all but stores ten percent of what they eat.
Explanation:
For example, a plant produces 100 percent energy. The plant needs to use the energy for survival.
When a cow eats the plant, it only gains 10 percent of the energy.
Then, say a wolf eats the cow.
The wolf only gets 1 percent of the energy that is produced by the plant.
Algae clogs the mouths of the fish, preventing them from eating, The algae use up the oxygen in the water as they photosynthesize When the algae die, their decomposers use up the oxygen in the water.
Nucleus controls the cell, it tells the cell what to do, similar to a brain. Rough ER or Ribosome ER creates the proteins in the cell. Golgi Apparatus packages macromolecules like lipids and proteins for transport.
All of these components are reservoirs of carbon. The cycle is usually discussed as four main reservoirs of carbon interconnected by pathways of exchange. The reservoirs are the atmosphere, terrestrial biosphere (usually includes freshwater systems), oceans, and sediments (includes fossil fuels).
