1. Warm Up and
Four friends visited an island. The island was far away from the mainland. No humans lived on the island. The friends talked about what would happen if all the plants disappeared on the island. This is what they said:
Juan: “I think all the animals on the island would eventually die.”
Stephanie: “I think the animals that eat plants would eventually die but the animals that eat both plants and animals would live.”
Carlos: “I think only the predators on the island would live.”
Christina: “I think eventually all the animals on the island will become meat eaters, and they will survive without plants.”
QUESTION: Which friend do you agree with the most? Explain why you agree.

2. Where have we been? Where are we going?
We have talked about so many different interactions and how they really keep ecosystems balanced…
Organisms with organisms
Organisms with environments
But why is this even important? Why do we care?
Can you think of any reasons why protecting and conserving as many plants AND animals is important? g
