2 Anne was investigating the animals that lived in a wood. She collected all the dead leaves in 0.5 m2 of the wood and put them in a Tullgren funnel. The light on the funnel
makes the animals move away from it, and they fall into the beaker.

4 Porous rocks can absorb water.
Joe tested some rocks to see how porous they were.
Joe found the mass of each rock, then put it into some water. He left the rocks in the water for ten minutes, then he took them out and wiped them with a paper towel before he found the mass again.
The table shows his results.
