B. Heart, because the heart circulates blood throughout your body.
It’s gases. Gas particles are always moving around. They have no fixed position and so they have high energies. Density depends on how many particles are present, so if the gas particles move around freely there will be very less density, but if you compress them their particles will increase in number thereby increasing the density
American prairie, bison and badgers don't live in any of the other options naturally.
The right option is; A. Solar
Solar energy is sustainable.
Solar energy is considered as a renewable energy resource. Solar energy is sustainable because it occurs naturally and it is derived from a source that is inexhaustible (sun). It can be depended on for the long term. All renewable energy sources such as geothermal, wind, biomass and hydro are sustainable.
Answer
The correct order to describe the carbon cycle would be;
• The carrot plant takes in carbon dioxide from the air during photosynthesis(3)
• The rabbit eats the carrot plant(2)
• The rabbit decomposes(1)
• The carbon compounds are returned to the soil (4)
Explanation
Carbon is captured in the food web through autotrophs (carrot plant) which undergo the process of photosynthesis. The captured carbon will utilized in making organic compounds (glucose). Heterotrophs (the rabbit) will feed on the carrot to allow the organic carbon to proceed into the food chain. Decomposers (acting on dead rabbit) release organic compounds and carbon iv oxide during breaking down of the decomposing matter. Biologically carbon is returned to the environment and soil after this stage.
