Why are some plants able to survive and grow in the nutrient-poor soils of the Brazilian rainforest?

• Some plants have adapted to absorb nutrients efficiently from limited resources in the soil.

• The rainforest has fewer animals, so plants face less competition for space.

• The soil in the rainforest is always wet, which provides all the nutrients plants need.

• Plants in the rainforest do not need sunlight to grow well.

While hiking through the Brazilian rainforest, Mia observes that the soil is very poor in nutrients. What adaptation allows some plants to flourish in the nutrient-poor soils of the Brazilian rainforest?

• They have developed specialized roots to maximize nutrient uptake from the soil.

• They rely on animals to bring them nutrients directly.

• The soil is rich in minerals, so no adaptation is needed.

• They do not require water to survive.

The diagram shows the natural changes to a pond over time. Match each description to the correct stage.

• Stage 3

• Pond is deep with many aquatic plants and animals.

• Stage 1

• Pond continues to fill in, grasses and shrubs begin to grow.

• Stage 2

• Pond becomes filled with soil, trees grow and the pond changes into a forest.

• Stage 4

• Sediments build up, pond becomes shallower, more plants grow around the edges.
