the role of plants in carbon cycle
Explanation:
the amount of CO2 found in the atmosphere varies over the course of a year. much of this variation happens because of the role of plants in carbon cycle...respiration occurs all the time, but domains during the colder months of the year, resulting in higher CO2 levels in the atmosphere during those months.
The last answer box: Can be depended on
Heterotrophs are organisms that depend on other organisms for food. For example, a bird would be a heterotroph. A bird eats other organisms like worms and beetles. A plant would be an example of an autotroph, which is an organism that makes it’s own food.
The correct answer would be D. gets food from outside itself.
C. The small rocks are mechanically weathering the larger rocks and erosion is morning the pieces downstream
There is no chemical change in this so it has to be mechanically. Than erosion is causing the rocks to be moving the pieces downstream. Deposition means another thing...
