How does carbon cycle through Earth's systems? A. As fossil fuels are burned, carbon dioxide is made available for
photosynthesis in animal cells. When the animals die, carbon is
released into the soil, and the animal remains form new fossil
fuels.
B. Animals absorb carbon dioxide through their skin. Dead animals
release carbon into the soil. Plants absorb the carbon from the soil
and release carbon dioxide during photosynthesis.
C. Plants absorb carbon dioxide through their leaves. Animals take in
the carbon when they eat the plants. Animals exhale carbon
dioxide. Dead plants and animals release carbon into the soil.
D. Photosynthesis releases carbon dioxide into the atmosphere.
Cellular respiration uses carbon dioxide.

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.
