Understanding how energy moves through nature is key to managing ecosystems. Environmental science basics show how living things in their homes are linked through food chains and webs.

Our world is like a big network where every living thing is important. Energy moves up levels, showing how survival and help depend on each other⁹.

What is a Food Chain?

A food chain is a line of energy flow between living things. It begins with plants and goes through different levels of consumers⁹:

Producers (Plants): First trophic level
Primary Consumers (Herbivores): Second trophic level
Secondary Consumers (Carnivores): Third trophic level
Tertiary Consumers: Fourth trophic level

Understanding Food Webs

Food webs are more complex than chains, showing many connections between species. They show how energy moves in many ways⁹.

Trophic Levels Explained

Energy gets less efficient as it goes up the levels. Only about 10% of energy is passed on from one level to the next⁹. This is why there are fewer animals at higher levels.

Trophic Level	Energy Transfer Efficiency
Producers	100%
Primary Consumers	10%
Secondary Consumers	1%
Tertiary Consumers	0.1%

Knowing how ecosystems work helps us protect and manage them better¹⁰.

The Role of Energy in Ecosystems
