Bioaccumulation is accumulating a substance over time inside a single living organism. Biomagnification
is the process by which a compound becomes concentrated in the tissues of organisms as it makes its
way up the food chain.
each of several levels in an ecosystem. Each level consists of living creatures that share the same
function in the food chain and get their food from the same source
A food chain is a linear sequence of transfers of matter and energy in the form of food
from organism to organism12. It starts with producers (such as plants or algae) and
typically ends with apex predators, detritivores, or decomposers2. Food chains
intertwine locally into a food web because most organisms consume more than one
type of animal or plant1
A food web is a complex network of interconnecting and overlapping food chains
showing feeding relationships within a community123. A food web illustrates how
matter and energy from food are transferred from one organism to another in an
ecosystem13. A food web can include different kinds of consumer-resource interactions,
such as herbivory, carnivory, scavenging, and parasitism2
