Food Webs and Energy Pyrmaids

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

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 top.

Producers are organisms, like plants, that create their own food through photosynthesis and form the base of the food web.

Consumers are organisms that cannot produce their own food and rely on eating other organisms for energy.

Herbivores are animals that primarily eat plants.

Carnivores are animals that primarily eat other animals.

Omnivores are animals that eat both plants and animals.

A trophic level is a position in a food chain or food web, representing the flow of energy from one level to the next.

Typically, only 10% of energy is passed from one trophic level to the next.

Decomposers are organisms, like fungi and bacteria, that break down dead organic matter, returning nutrients to the soil.
