Design a food web with the Barn Owl as the top consumer.
- Your web should have at least 4 trophic levels.
- Arrows must show the transfer of energy from prey to predator.
- Use the following list of common owl prey and their eating habits*:
- Mouse - It eats a wide variety of plant and animal matter depending on what is available, including insects and other invertebrates, seeds, fruits, flowers, nuts, and other plant products. Deer mice sometimes eat their own feces (this is called coprophagy).
- Mole - A mole's diet is mostly insects and other invertebrates, including earthworms, centipedes, millipedes, snails, slugs, grubs, ants, sowbugs, termites, beetles, and crickets.
- Shrew - Food habit studies have revealed that shrews eat beetles, grasshoppers, butterfly and moth larvae, ichneumonid wasps, crickets, spiders, snails, earthworms, slugs, centipedes, and millipedes. Shrews also eat small birds, mice, small snakes, and even other shrews when the opportunity presents itself.
- Rat - The rat's diet typically includes seeds, nuts, grains, vegetables, fruits, meats and invertebrates. They consume about one-third of their weight in food every 24 hours. Because of their inability to vomit, rats are very hesitant to try new foods that may be poisonous. They will take a small nibble and wait to see if they feel sick and, if so, will avoid that food in the future.
- Bird - Birds eat insects; terrestrial non-insect arthropods, seeds, grains, and nuts; fruit.
