Question

Why do plants grow in some places and not in others? Why does some land have so much growing on it, while other land has almost no plants growing on it at all? To grow, plants need several things. One is warmth. In very cold places almost nothing grows. That’s why dry deserts everywhere are almost not covered by trees or grass.

Plants must also have a place in which to put down their roots and grow. They find it difficult to grow on hard land. The town is built on hard land. The paints here have only the soil found between thecracksof the stones to grow in.

Another thing plants must have before they can grow is food.

What will happen if we try to make things grow on the sandy beach? A few plants, such as beach grass, will grow in sand, but most plants won’t. Even if the weather is warm enough and we water the plants each day, many of them will die because the sand on this beach has almost no food for plants.
