Some student made a terratium out ot the bottom of 2-liter soda bottle.They placeed a layer of gravel on the botton of the bottom of the and the added soil.they sprinkled 1/2 teaspoon of grass seed on top of the soil and added two small plants.Finally they waterd the plant and covered the top of the bottle with plastic wrap.At the end of a month, they notice that the grass had grown 2 cm and the plant werw thriving.This is most likely because-

Answer 1

This controlled environment had sufficient quantities of light, water, and nutrients to grow these plants.

Answer 2

don't plants need moisture, soil nutrients, and light?

Answer 3

This is most likely because the terrarium provides an ideal environment for the plants to grow and thrive. Let's break down the factors that contribute to this:

1. Enclosed Space: The 2-liter soda bottle, with the top covered by plastic wrap, creates a closed environment. This enclosure helps to trap moisture and create a greenhouse effect, which promotes plant growth.

2. Gravel Layer: By placing a layer of gravel at the bottom of the bottle, it serves as a drainage system. This helps prevent water from stagnating at the bottom, ensuring that the roots of the plants don't become too saturated and develop root rot.

3. Soil: Adding soil on top of the gravel layer provides necessary nutrients and a medium for the plants to anchor their roots. The soil acts as a support system for the plants, allowing them to establish themselves and grow.

4. Grass Seed: Sprinkling grass seeds on top of the soil provides an opportunity for new grass to grow. Grass seeds require proper moisture, warmth, and sunlight to germinate and develop into grass shoots. The enclosed and controlled environment of the terrarium helps maintain these optimal conditions.

5. Watering and Moisture: Watering the plants ensures that they receive the necessary moisture to grow. The enclosed environment minimizes water loss through evaporation, allowing the plants to retain moisture for a longer period. This constant supply of water helps the plants thrive.

Overall, the combination of an enclosed space, proper drainage, suitable soil, seeds, and watering contribute to the growth and success of the grass and other plants in the terrarium.
