Answer:
B. they cannot absorb carbon directly from the air.
Explanation:
Carbon cycle refers to the series of processes through which carbon is exchanged between living and non living components of the environment. During the carbon cycle, animal organisms feed on one another in order to obtain energy, a characteristics that makes them HETEROTROPHIC.
Unlike plants, animals cannot perform photosynthesis, which turns solar energy into biomass (carbon-based). Plants get their carbon source (CO2) directly from air via the stomata on their leaves. Animals, on the contrary, cannot get carbon this way, hence, they need to feed on other animals to get their carbon and energy source.
The coefficient of thermal expansion should be low. This is because when tyres roll they get heated up and transfer this heat to the medium contained by the tyre causing it to expand.
