at the start of a food chain<br />

Consumer<br />
an organism<br />
that gains<br />
energy by<br />
consuming other<br />
organisms<br />
CONSUMER<br />
Herbivore<br />

OBTAINS ENERGY BY<br />
feeding on producers<br />
Omnivore<br />
feeding on producers and other<br />
consumers<br />
Carnivore<br />
feeding on other consumers<br />
Decomposer<br />
breaking down dead matter<br />
Some microorganisms<br />
are helpful in<br />
ecosystems, breaking<br />
down dead matter or<br />
acting as a food source.<br />
Other microorganisms<br />
are harmful, spreading<br />
disease or consuming<br />
resources needed by<br />
consumers.<br />
Human activities<br />
can damage the<br />
environment. Our<br />
actions can destroy<br />
ecosystems or reduce<br />
biodiversity.<br />
Human activities<br />
can also help the<br />
environment, such as<br />
using science to fight<br />
bushfires or changing<br />
the way we grow crops.<br />
