1.) kinetic (sun, thermal, battery, mechanical)
2.) chemical energy (nuclear, gravitational, magnetic)
different types of organisms:
- Producer → makes its own organic nutrients

organic materia

explain food web
has interconnected food chains, and shows a more complex idea of a who eats whom situation. it clearly shows the reltionships between different organisms.
what is trophic level
is the position of an organism in a food chain, food web or
ecological pyramid.
what is pyramids of numbers
