FAQ

How do I use this symbiosis and predators worksheet?

⌄

Use Analyze Organism Interactions first for general interactions, then Test Symbiosis Claims for the three types of symbiosis.

What does this worksheet teach?

⌄

Use survival data for acacias and ants to name mutualism, commensalism or parasitism and draw bars. The directions on the page read: Use the definitions and data to write each effect and name each relationship. An answer key is included.

Can I use this symbiosis and predators worksheet for homeschool or classroom?

⌄

Yes, both. We made it for 7th grade ecosystems, and it works the same at home or at school. At home, a student can work through it alone and then go over it with you, which shows quickly what is solid and what needs another look. In class it works as independent practice, homework or a warm-up, and you can print one copy or a full set.

What is mutualism?

⌄

Mutualism is a relationship in which both species are helped, so their numbers rise together.

How is commensalism different from parasitism?

⌄

In commensalism one species is helped and the other has no real change. In parasitism one species is helped and the other is harmed.

How do predator and prey graphs look?

⌄

Predator numbers rise and fall a little after prey numbers do.
