Complete the sentence. Carbon flows between ____________, environmental storage centers that absorb and store carbon for long periods of time.
plants and animals
humans and air
rocks and soil
carbon sinks
Carbon is transfered by plants and animals.
Carbon flows between plants and animals, environmental storage centers that absorb and store carbon for long periods of time. Thus, the correct option is A.
What is Carbon cycle?Carbon cycle is one of the main biogeochemical cycles which has four main steps. In this first, carbon enters into the atmosphere as CO₂. CO₂ is absorbed by the autotrophs such as green plants for photosynthesis. Then, the animals consume plants as food, thereby, incorporating the carbon into their system. Afterwards, animals and plants die, their bodies decompose and the carbon is reabsorbed back into the atmosphere.
In this, plants use carbon dioxide for photosynthesis. Through this, they remove the inorganic carbon from the atmosphere and incorporate it into the plant's tissues in the form of sugars such as glucose, sucrose and starch. Animals get carbon by eating the plants or by hunting other animals.
Therefore, the correct option is A.

Which statement accurately compares these flashlights?
O A. The smaller flashlight has less inertia than the larger flashlight, so
it takes less force to change the motion of the smaller flashlight.
O B. The smaller flashlight has more inertia than the larger flashlight,
so it takes more force to change the motion of the smaller
flashlight.
C. The smaller flashlight has less inertia than the larger flashlight, so
it takes more force to change the motion of the smaller flashlight.
O D. The smaller flashlight has more inertia than the larger flashlight,
so it takes less force to change the motion of the smaller
flashlight
The smaller flashlight has less inertia than the larger flashlight, so it takes
less force to change the motion of the smaller flashlight.
Inertia is defined as the property of an object to resist changes in its velocity
when in motion. A larger or bigger body has more mass and inertia as it
requires more force to change the direction of the object.
The smaller flashlight has less inertia than the larger flashlight and hence
requires less force to change its motion due to its smaller size.
