U4: L1 The Flow of Energy Drives the Cycling of Matter

Front

What is the law of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

What are producers in an ecosystem?

Back

Organisms that produce their own food through photosynthesis, forming the base of the energy pyramid.

Front

What is an energy pyramid?

Back

A graphical representation showing the flow of energy through different trophic levels in an ecosystem.

Front

Where is energy the highest in a food chain?

Back

Energy is highest at the producer level, such as grass.

Front

What is photosynthesis?

Back

The process by which green plants use sunlight to convert water and carbon dioxide into glucose and oxygen.

Front

What role do consumers play in an ecosystem?

Back

Consumers are organisms that obtain energy by eating other organisms.

Front

What are the different types of consumers?

Back

Primary consumers (herbivores), secondary consumers (carnivores), and tertiary consumers (top predators).

Front

What is a food web?

Back

A complex network of feeding relationships among various organisms in an ecosystem.

Front

How does energy flow through an ecosystem?

Back

Energy flows from producers to consumers and then to decomposers in a one-way direction.

Front

What are decomposers?

Back

Organisms that break down dead organic material, returning nutrients to the soil.
