Unit 3: Energy

A secondary consumer is an organism that eats primary consumers (herbivores) in a food chain. In the provided food chain, the fish is a secondary consumer as it feeds on the grasshopper.

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.

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

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

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

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

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

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

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

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