Matter and Energy in Ecosystems Chapter 3

Front

What is matter?

Back

Matter is anything that has mass and takes up space. It can exist in different states, such as solid, liquid, and gas.

Front

What is energy?

Back

Energy is the ability to do work or cause change. It exists in various forms, including kinetic, potential, thermal, and chemical energy.

Front

What are ecosystems?

Back

Ecosystems are communities of living organisms interacting with their physical environment, including both biotic (living) and abiotic (non-living) components.

Front

What role do producers play in an ecosystem?

Back

Producers, such as plants, create their own food through photosynthesis and provide energy for consumers in the ecosystem.

Front

What are consumers in an ecosystem?

Back

Consumers are organisms that cannot produce their own food and rely on eating other organisms (plants or animals) for energy.

Front

What are decomposers?

Back

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

Front

What is the carbon cycle?

Back

The carbon cycle is the process by which carbon moves through the atmosphere, land, and oceans, involving processes like photosynthesis, respiration, and decomposition.

Front

How do fossil fuels form?

Back

Fossil fuels form from the remains of dead plants and animals that have been buried underground for millions of years, undergoing heat and pressure.

Front

What is photosynthesis?

Back

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

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.
