<u>Answer</u>: The carbon could go into the atmosphere through cellular respiration, it could become part of the acacia tree (biosynthesis), it could die and move to the soil, or an herbivore could eat the leaves of the acacia tree.
This answer contains <em>all </em>the possible routes for carbon.
Carbon originating from
will either return to the atmosphere due to cellular respiration or become part of the tree. The bio-synthesized carbon can either move into an herbivore through the eaten leaves, or into the soil after the tree dies.
Due to the large amounts of carbon used by for growth, trees are extremely important for the removal and fixation of atmospheric
.
Answer: It absorbs food from the outside environment.
<span>When you put the cells in a salt solution you are placing the cells into a hypertonic solution. That means the solute concentration outside the cell is higher than the solute concentration inside the cell. You should know from your own studies that water will move from areas of high water concentration to areas of low water concentration. A hight solute concentration means there is low water concentration. That means that the water will move from the onion cell and out into the hypertonic solution and the onion cell will shrivel up.</span>
Answer: True.
Explanation:
Humus are decayed dead plants and animals in the soil. They are decayed organic matter(plants and animals). They are formed by the incorporation of plants and animals matter in the soil by the action of microorganisms. Humus provide nutrients for the soil, increase soil porosity and create good soil tilth. The good soil with help microganisms to perform their actions in the soil and improve soil structure.
