Matter Cycling in Ecosystems: 5th grade science NGSS 5.3

Front

What is matter cycling in ecosystems?

Back

Matter cycling in ecosystems refers to the movement and transformation of matter (like nutrients) through living organisms and the environment, ensuring that essential elements are reused and recycled.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which plants use energy from the sun to convert carbon dioxide and water into glucose (food) and oxygen.

Front

What do plants need to grow?

Back

Plants need sunlight, water, nutrients, and carbon dioxide to grow.

Front

What is decomposition?

Back

Decomposition is the process by which dead organic matter is broken down by microorganisms, returning nutrients to the soil.

Front

Why do plants need soil?

Back

Plants need soil primarily to obtain nutrients and water necessary for their growth.

Front

What role do bacteria play in decomposition?

Back

Bacteria help break down dead organic matter, releasing nutrients back into the soil.

Front

What happens to nutrients in decomposed matter?

Back

Nutrients from decomposed matter are returned to the soil, where they can be taken up by plants.

Front

Can plants grow in water?

Back

Yes, some plants can grow in water, but they need liquid nutrients added frequently.

Front

What is the role of sunlight in photosynthesis?

Back

Sunlight provides the energy needed for plants to convert carbon dioxide and water into glucose.

Front

What is the importance of oxygen for plants?

Back

Oxygen is essential for plants during respiration, which helps them convert glucose into energy.
