Cycles of Matter

Front

What are cycles of matter?

Back

Cycles of matter refer to the natural processes through which essential elements and compounds are recycled in ecosystems, including the water cycle, carbon cycle, nitrogen cycle, and phosphorus cycle.

Front

What is the carbon cycle?

Back

The carbon cycle is the process by which carbon is exchanged among the atmosphere, land, water, and living organisms, involving processes like photosynthesis, respiration, decomposition, and combustion.

Front

What are producers in an ecosystem?

Back

Producers are organisms, such as plants and algae, that can make their own food through photosynthesis, using sunlight, carbon dioxide, and water.

Front

What are primary consumers?

Back

Primary consumers are organisms that eat producers; they are typically herbivores that obtain energy by consuming plants.

Front

What are secondary consumers?

Back

Secondary consumers are organisms that eat primary consumers; they can be carnivores or omnivores.

Front

What is the role of decomposers in the cycles of matter?

Back

Decomposers break down dead organic matter, returning nutrients to the soil and making them available for producers, thus playing a crucial role in nutrient cycling.

Front

How do oceans contribute to the carbon cycle?

Back

Oceans act as carbon reservoirs, absorbing carbon dioxide from the atmosphere and storing it in water, which helps regulate global climate.

Front

What is the nitrogen cycle?

Back

The nitrogen cycle is the process through which nitrogen is converted between its various chemical forms, including fixation, nitrification, denitrification, and ammonification.

Front

What is an example of carbon accumulation in the geosphere?

Back

Formation of fossil fuels from the remains of dead organisms is an example of carbon accumulating in the geosphere.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which producers convert light energy from the sun into chemical energy in the form of glucose, using carbon dioxide and water.
