- water

- gold

- oxygen

- hydrogen

Which are limiting nutrients for plant growth?

- water and nitrogen

- nitrogen and carbon

- carbon and phosphorus

- phosphorus and nitrogen

The ocean and the atmosphere serve as long-term storage areas for carbon and other nutrients. What are these storage areas called?

- reservoirs

- fossil fuels

- biostorages

- compounds


Substance that is a compound: water

Limiting nutrients for plant growth: phosphorus and nitrogen

Long-term storage areas for carbon and nutrients: reservoirs


In the natural world, ecosystems rely on various substances and nutrients for growth and sustainability. Understanding the composition of these essential elements is crucial in managing ecological systems.

Water is a compound because it is composed of distinct elements, making it a vital resource for life on Earth. In terms of plant growth, phosphorus and nitrogen are considered limiting nutrients as they can significantly impact the development and health of plants.

When it comes to long-term storage of carbon and other nutrients, the ocean and the atmosphere act as reservoirs. These storage areas help regulate nutrient cycles and maintain balance within ecosystems.
