Certainly! Let's analyze the food chain and calculate the amount of energy that the zooplankton received from the phytoplankton based on the given information.
The food chain provided is:
phytoplankton → zooplankton → bivalves → sea ducks → bald eagle
Given:
1. A bald eagle acquires 50 kg of energy.
Next, let's work our way backward through the food chain to determine the amount of energy at each level:
1. Bald eagle: The bald eagle receives 50 kg of energy.
2. Sea Ducks' Energy: Birds like sea ducks would provide this energy to the bald eagle.
- To find the sea ducks' energy, we multiply the bald eagle's energy by 10.
- Energy of sea ducks = 50 kg 10 = 500 kg.
3. Bivalves' Energy: Next, bivalves provide energy to the sea ducks.
- To find the bivalves' energy, we multiply the sea ducks' energy by 10.
- Energy of bivalves = 500 kg 10 = 5,000 kg.
4. Zooplankton's Energy: Zooplankton provide energy to the bivalves.
- To find the zooplankton’s energy, we multiply the bivalves' energy by 10.
- Energy of zooplankton = 5,000 kg * 10 = 50,000 kg.
Therefore, the zooplankton received 50,000 kg of energy from the phytoplankton.
