The scientist first designed thee geologic time scale because.... the people who needed to understand the geological relationship of different rock units were miners. Mining had been of commercial interest since at least the days of the Romans, but it wasn't until the 1500s and 1600s that these efforts produced an interest in local rock relationship.
Answer:
Carbon enters the atmosphere as carbon dioxide from respiration and combustion. Carbon dioxide is absorbed by producers to make glucose in photosynthesis. ... Decomposers break down the dead organisms and return the carbon in their bodies to the atmosphere as carbon dioxide by respiration
Explanation:
Carbon enters the atmosphere as carbon dioxide from respiration and combustion.
Carbon dioxide is absorbed by producers to make glucose in photosynthesis.
Animals feed on the plant passing the carbon compounds along the food chain. Most of the carbon they consume is exhaled as carbon dioxide that was formed during aerobic respiration. The animals and plants eventually die.
Decomposers break down the dead organisms and return the carbon in their bodies to the atmosphere as carbon dioxide by respiration. In some conditions, decomposition is blocked. The plant and animal material may then be available as fossil fuel for combustion in the future.
An archaeologist studies the lives of early humans by examining artifacts. Archaeology is essentially the study of human life, as well as material culture and environmental data which can explain how people in history lived. This includes prehistory and history. Archaeologists use different ways to identify this through surveying, excavation and analysis of data collection.
