Food Webs, Energy Pyramids

Front

What is a food web?

Back

A food web is a complex network of interconnected food chains in an ecosystem, showing how energy and nutrients flow between different organisms.

Front

What is an energy pyramid?

Back

An energy pyramid is a graphical representation that shows the flow of energy at different trophic levels in an ecosystem, with producers at the base and top predators at the apex.

What is a producer?

Back

A producer is an organism that can make its own food through photosynthesis or chemosynthesis, such as plants.

Front

What is a consumer?

Back

A consumer is an organism that cannot produce its own food and must eat other organisms for energy.

Front

What is a primary consumer?

Back

A primary consumer is an herbivore that eats producers (plants) for energy.

Front

What is a secondary consumer?

Back

A secondary consumer is a carnivore that eats primary consumers.

Front

What is a decomposer?

Back

A decomposer is an organism that breaks down dead organic material, returning nutrients to the soil, such as fungi and bacteria.

Front

What role do plants play in a food web?

Back

Plants are producers that form the base of the food web, providing energy for primary consumers.

Front

Where does energy in a food chain originate?

Back

Energy in a food chain originates from the sun, which is captured by producers through photosynthesis.

Front

What is the significance of the sun in an energy pyramid?

Back

The sun is the primary source of energy for all ecosystems, and its energy is transferred through the food web, starting with producers.
