Plants who eat

• Not common

• Examples include Venus Fly Trap, Sundew and Pitcher plant

• Use ENZYMES :chemicals that break big molecules into small molecules (digest)

Mineral poor soil• Soil that lacks phosphorous, potassium and

nitrogen• NORMAL soil : (ex. garden): bugs, bacteria

and mold (decomposers) turn big molecules into small molecules of potassium, nitrogen and phosphorus

• Plants use those minerals to make cell walls, chloroplast, mitochondria

• Because of the water, few decomposers in a bog, so little minerals.

Life on a bog

• Water covered with thick, woody moss

• Moss can be cut, dried and used for fuel

• Bog can have deep water

• Soil is made of plants…no dirt

Bog

•

BOG• Notice open water

Exmoor, England

• Notice drainage ditches, and harvesting paths for the peat moss

Therefore….

• Plants eat! Lots of nitrogen (N), Phosphorus (PO4), and Potassium (K) in a bug

How do they break down bug molecules?

• Enzymes found in glands• Gland is a bunch of cells in one place that

make enzymes• In us… salivary glands in mouth, pancreas

has glands that make insulin and other enzymes

Bog mummies; bodies do not decompose• "Yde Girl“ 16-year

old child• Netherlands. • first century A.D., • along with remnants

of woollen clothing.• The remains of the

woollen cord with which she was strangled can still be seen around her neck.
