Answer: this are no options on this question.Here are some facts about the carbon cycle-
It involves the circulation of the element carbon
It ensures that the element is constantly being reused.
Explanation:in nature, nutrients move through the biosphere.it involves movement from the environment eg the air,soil etc, to the organism in a cyclic matter.this cyclic movement ensures that the nutrients are not exhausted and are continually reused.examples of nutrients that undergoes such cycles are carbon, nitrogen etc.
Water too had it's cycle in nature.
In The carbon cycle, carbon dioxide is taken up by autotrophs to produce carbonhydrate. Then heterotrophs takes up the carbonhydrate found in plant .then carbon dioxide is given off and the plants takes up this carbon dioxide for photosynthesis and the process continues.
Carbon can be also returned to the atmosphere by combustion of wood and coal .
b. 4y = 12x
c. 3y = 4x
d. 3y= 12x
-the least informative property of a mineral
-measured using the Mohs scale
-the way a mineral splits when stressed
Answer: measured using the Mohs scale
Explanation:
Hardness is defined as ability of the surface to undergo resist deformation.
The degree of hardness is determined by observing the comparative ease or difficulty which which one mineral is scratched by another.
Color is the least informative property of a mineral.
Mohs scale of hardness gives a rating of 1 to talc which is categorized as most soft and rating of 10 to diamond which is categorized as most hard.
Hardness is the physical property of mineral measured using the Mohs scale. Hardness is property of mineral to resist scratch. On Mohs scale minerals are classified according to their hardness. Hardest mineral on the scale is Diamond. While the softest mineral is Talc. Different test are done to test the hardness of minerals. These includes, test of scratch from finger nail, test of scratch from knife/blade and test of mineral by a piece of glass. On Mohs scale minerals are classified according to their hardness:
10. Diamond
9. Corundum
8. Topaz
7. Quartz
6. Orthoclase
5. Apatite
4. Fluorite
3. Calcite
2. Gypsum
1. Talc
Answer:
An ecological pyramid is a graphical representation of the distribution of the biomass to different organisms in successive trophic levels. The energy is being lost by 10% in every higher trophic level, when one organism is consumed by another organism in a food chain. Therefore, the number of trophic levels in a pyramid will be limited.

O 50%
O 63%
A dry soil sample has a volume of 500 mL. After 400 mL of water are added to the soil, the soil becomes saturated with 150 mL of surface water left on top. The porosity of the soil is 50%. Thus, option C is correct.
Forest soil has more moisture than sandy soil therefore the types of plants that are grown in soil of forests are more qualitative and more superior than the sandy plants which are facing certain limitations and facing certain situations.
Forest soil supports plant life, but sandy soil does not support any plants. Forest soil produces more superior life and the plants life are found in the forest area and the sandy plants are lesser found in the sandy areas.
The reason for vegetation in forests is because of the supportive factors that are involved in the good plants life. The soil type that is the richest in organic material would be a dark-colored soil. Decaying matter turns brownish-black which makes this type of soil having a dark color even almost black.
Therefore, A dry soil sample has a volume of 500 mL. After 400 mL of water are added to the soil, the soil becomes saturated with 150 mL of surface water left on top. The porosity of the soil is 50%. Thus, option C is correct.
