Test: 3rd Grade Science

1.

Amazon Rainforest: In the Amazon Rainforest is rains almost every day. There are very tall trees that create a canopy, and the ground of the forest is covered in plants. The plants on the ground try to grow wide or tall to reach sunlight. The very tall trees can block much of the sunlight.

Bromeliads: Bromeliads grow on tree trunks and branches and wrap their roots around the trees. They need wet habitats to grow well. They have a center portion like a cup or bowl that collects water. Their leaves are waxy, and the water slides into the center. The leaves are long and curved to collect water.
 
Janine says that she believes bromeliads would do well in the Amazon Rainforest, while Natalie thinks they will not do well in that habitat. Who (if anyone) is correct and has an argument that supports their point of view?

Janine is correct. Bromeliads would do well in the rainforest because they are adapted to wet habitats, shaped to collect water, so they stay hydrated and grow on trees that are plentiful in the rainforest.

Natalie is correct. Bromeliads would not do well in the Amazon Rainforest habitat because they would receive too much water, not enough sunlight, and would not have an adequate place to live.

Neither Natalie and Janine are correct with their explanations of why bromeliads would or would not do well in the Amazon Rainforest habitat.

Both Natalie and Janine are partially correct. It depends on the plant and whether it feels like the Amazon Rainforest is where it wants to live.
