Amplify Matter & Energy in Ecosystems

Front

What is a biotic factor in an ecosystem?

Back

A biotic factor is a living component of an ecosystem, such as plants, animals, and microorganisms. For example, a tree is a biotic factor.

What is a key process that removes carbon from the atmosphere?

Back

Photosynthesis is the process that removes carbon from the atmosphere, as plants convert carbon dioxide into glucose using sunlight.

Front

How does carbon move in and out of living things?

Back

Carbon moves into and out of living things through processes like photosynthesis (carbon enters) and respiration (carbon exits).

Front

Which group of organisms should be studied to understand photosynthesis in a forest ecosystem?

Back

Plants should be studied to understand photosynthesis, as they are the primary producers that perform this process.

Front

Where does cellular respiration occur in a cell?

Back

Cellular respiration takes place in the mitochondria, which are known as the powerhouse of the cell.

Front

What is the role of decomposers in an ecosystem?

Back

Decomposers break down dead organic matter, returning nutrients to the soil and helping to recycle matter in the ecosystem.

Front

What is an example of an abiotic factor in an ecosystem?

Back

An abiotic factor is a non-living component of an ecosystem, such as sunlight, water, or rocks.

Front

What is the process by which plants make their own food?

Back

Photosynthesis is the process by which plants use sunlight, carbon dioxide, and water to produce glucose and oxygen.

Front

What is the significance of the mitochondria in cells?

Back

Mitochondria are important because they generate energy for the cell through the process of cellular respiration.

Front

How do animals contribute to the carbon cycle?

Back

Animals contribute to the carbon cycle through respiration, which releases carbon dioxide back into the atmosphere.
