level consumer, or decomposer.
• Tomatoes = producer
• Aphids = 1st level consumer, Primary consumer
• Lacewings / lady beetles = 2nd level consumer,
secondary consumer
• Spiders = 3rd level consumer, tertiary consumer
4. Draw/Write SNAKE in the food web
where it would belong.
5. Draw arrows in the food web to
