Lauren and her classmates created a terrarium ecosystem. They wore gloves to handle the soil, water, and plants. Then their teacher added populations of mealworms, pill bugs, and toads. The toads are carnivores, while the pill bugs and mealworms are herbivores. The students observed the terrarium each day and made notes about how the plants and animals looked and how many of each they could see. If their teacher removed the toads, what interaction would the students be likely to see between the remaining animals and their environment?
There will be more mealworms and pill bugs.
There will be fewer mealworms and pill bugs.
There will be more plants and fewer mealworms.
There will be more pill bugs, mealworms, and plants.

layers of limestone rock.
the deepest rock layers.

The fish fossil is older than the plant fossil.
The plant fossil is older than the fish fossil.
When they were alive, the plant was larger than the fish.
