Answer:
Animals gain energy from the food they eat. Some animals eat plants while others eat other animals. This is passing of energy from the sun to plants to animal to other animals is called a food chain
Hey day is the method of harvesting tress.
Answer : The age of the artifact is, 
Explanation :
Half-life = 5715 years
First we have to calculate the rate constant, we use the formula :


Now we have to calculate the time taken to decay.
Expression for rate law for first order kinetics is given by:

where,
k = rate constant
t = time taken by sample = ?
a = initial activity of the reactant = 58.2 counts per minute
a - x = activity left after decay process = 42.8 counts per minute
Now put all the given values in above equation, we get


Therefore, the age of the artifact is,
