Cycling of Matter

Front

What is the cycling of matter?

Back

The cycling of matter refers to the continuous movement of elements and compounds through the environment, including the atmosphere, lithosphere, hydrosphere, and biosphere.

What are producers in an ecosystem?

Back

Producers are organisms, such as plants, that create their own food through photosynthesis and form the base of the energy pyramid.

Front

What are consumers in an ecosystem?

Back

Consumers are organisms that cannot produce their own food and rely on consuming other organisms for energy.

Front

What are decomposers?

Back

Decomposers are organisms, such as bacteria and fungi, that break down dead organic material, returning nutrients to the soil.

Front

What is the energy pyramid?

Back

The energy pyramid is a graphical representation of the energy flow in an ecosystem, showing the energy available at each trophic level.

Front

Why are decomposers important in an ecosystem?

Back

Decomposers are important because they recycle nutrients back into the soil, making them available for producers.

Front

What is nitrogen fixation?

Back

Nitrogen fixation is the process of converting atmospheric nitrogen into a form that organisms can use, such as ammonia.

Front

Why is nitrogen fixation necessary for life?

Back

Nitrogen fixation is necessary because most organisms cannot use atmospheric nitrogen directly and need it in a fixed form for growth.

Front

What role do herbivores play in the energy pyramid?

Back

Herbivores are primary consumers that eat producers and transfer energy from plants to higher trophic levels.

Front

Which organisms have the most energy in an ecosystem?

Back

Producers, such as plants, have the most energy in an ecosystem as they convert sunlight into chemical energy.
