food chains end with this, are usually bacteria or fungi that break down the remains of dead organisms and return this material to the soil decomposer
a method of illustrating the interrelationships between food chains in an ecosystem food web
used by ecologists to illustrate energy relationships in a food chain/it is divided into layers, each one represents a different type of organism in the food chain ecological pyramids
are organisms that eat plants herbivores
animals that eat other animals carnivores
is a very small organism, it obtains its energy and materials from the host (ex. fleas and ticks) parasite
