An autotroph is an organism that produces its own food from sunlight or chemical energy. Trees are examples of autotrophs as they use photosynthesis to create energy.

Front

Where is the energy in ATP stored?

Back

The energy in ATP is stored in the bond between the second and third phosphate groups.

Front

Which organism receives energy from the snake in a food chain?

Back

The hawk receives energy from the snake as it is a tertiary consumer that preys on the snake.

Back

Energy starts from the sun, which provides the energy needed for plants (producers) to grow.

Front

What is a food chain?

Back

A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.

Front

What is the role of producers in an ecosystem?

Back

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

Front

What is a heterotroph?

Back

A heterotroph is an organism that cannot produce its own food and instead consumes other organisms for energy.

Front

What is the difference between a food chain and a food web?

Back

A food chain is a simple linear path of energy flow, while a food web is a complex network of interconnected food chains.

Front

What is the significance of decomposers in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the soil and supporting plant growth.
