Cycle of Matter and Flow of Energy

Front

What is the cycle of matter?

Back

The cycle of matter refers to the continuous movement of elements and compounds through the biotic (living) and abiotic (non-living) components of an ecosystem.

What is the flow of energy in an ecosystem?

Back

The flow of energy in an ecosystem is the transfer of energy from one organism to another, primarily from producers to consumers, in a one-way direction.

Front

What role do producers play in the flow of energy?

Back

Producers, such as plants, convert solar energy into chemical energy through photosynthesis, forming the base of the food chain.

Front

What is cellular respiration?

Back

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

How does volcanic eruption affect the carbon cycle?

Back

Volcanic eruptions release carbon dioxide into the atmosphere, contributing to the carbon cycle and affecting climate.

Front

What is biomagnification?

Back

Biomagnification is the process by which the concentration of toxic substances increases in organisms at each successive trophic level.

Front

What happens to energy as it moves up trophic levels?

Back

As energy moves up trophic levels, it is lost as heat and used for life processes, resulting in less energy available for higher trophic levels.

Front

What is a food chain?

Back

A food chain is a linear sequence that shows how energy and nutrients flow from one organism to another in an ecosystem.

Front

What do the arrows in a food chain represent?

Back

The arrows in a food chain indicate the direction of energy flow from one organism to another.

Front

What is a trophic level?

Back

A trophic level is a position in a food chain or food web, defined by how an organism obtains its energy.
