What is a food web?

Back

A food web is a complex network of feeding relationships among various organisms in an ecosystem, showing how energy and nutrients flow through different trophic levels.

Front

What is a primary consumer?

Back

A primary consumer is an organism that eats producers (plants) to obtain energy. Examples include herbivores like rabbits and deer.

Front

What is a secondary consumer?

Back

A secondary consumer is an organism that eats primary consumers. They are typically carnivores or omnivores, such as foxes and raccoons.

Front

What is a carnivore?

Back

A carnivore is an animal that primarily eats other animals. They can be both predators and prey in their ecosystems.

Front

What is cellular respiration?

Back

Cellular respiration is a metabolic process in which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is the role of decomposers in an ecosystem?

Back

Decomposers break down dead organic matter, returning nutrients to the soil and helping to recycle energy within the ecosystem.

Front

What are lipids?

Back

Lipids are organic compounds that are insoluble in water, including fats and oils, and are important for energy storage and cell membrane structure.

Front

What are proteins?

Back

Proteins are large molecules made up of amino acids, essential for growth, repair, and functioning of cells and tissues.

Front

What is the significance of ATP in cellular processes?

Back

ATP (adenosine triphosphate) is the primary energy carrier in cells, providing energy for various biological processes.

Front

What happens to a food web if a primary consumer is removed?

Back

If a primary consumer is removed, it can lead to an increase in producer populations and a decrease in secondary consumer populations due to lack of food.
