Answer:
182,500 units.
Explanation:
<em>The answer would be </em><em>182,500 units of mercury.</em>
<u>Assuming there is an average of 365 days in a years, 10 years is therefore equal to:</u>
10 x 365 = 3650 days.
<u>The stingray eats 50 clams per day. Hence, the total number of clams that would have been eaten in 10 years equals:</u>
3650 x 50 = 182,500 clams
<u>Each clam accumulated 1 unit of mercury in its body from the water it lives in and there is no loss of mercury between the clam and the stingray. Hence, the total number of units of mercury the stingray would have accumulated in 10 years equals:</u>
182,500 clams x 1 unit = 182,500 units of mercury.
Because a caterpillar is a heterotroph and it cannot make its own food so it relies on the energy in plant sugars and by eating plants it gets energy from the sun in an indirect way. So to put it simply, the caterpillar uses light captured energy for energy.
