A plant is eaten by an insect, and a bird eats the insect. Where did the bird’s food energy ultimately come from?

Worked method: The Sun supplied energy captured by the plant in photosynthesis. Energy then moved through the insect to the bird; matter cycles, but energy flows through the system.

A neutral atom has 6 protons. How many electrons does it have?

Worked method: It has 6 electrons because a neutral atom has equal numbers of positively charged protons and negatively charged electrons.

A 3 V source is connected across a 6 Ω resistor. What is the current in this idealized circuit?

Worked method: Use I = V/R = 3 V ÷ 6 Ω = 0.5 A. This is a model calculation, not an instruction to build a circuit.

If 1 cm on a model represents 10 million km, about how far apart are two objects separated by 150 million km?

Worked method: 150 million ÷ 10 million = 15, so the model separation is 15 cm. Keep the scale and the real distance distinct.

What is one difference between matter cycling and energy flow in an ecosystem?

An atom has 8 protons. What identifies its element?

At the same voltage, what happens to current if resistance increases?

Why use astronomical units rather than kilometres for distances within the solar system?
