Consumer An organism that eats other organisms
Food Chain a diagram that shows a series of relationships between plants and animals that traces the path of energy and nutrients through an ecosystem
food web many food chains interconnected
energy pyramid a diagram that shows the amount of energy being lost in ecosystem
carnivore An animal that eats other animals/meat
omnivore An animal that eats both plants and animals
Primary Consumer (1st level consumer) Eats producers/ also called a herbivore
Secondary consumer (2nd level consumer) eats herbivores/also called a carnivore

decomposer an organism that gets energy by breaking down the remains of dead organisms or animal wastes and consuming or absorbing the nutrients
herbivore a consumer that eats primarily plants
10% rule Only 10% of the total energy produced at each trophic level is available to the next level. The amount of energy passed up to the levels of food pyramid reduces as you go up
abiotic factors Nonliving components of ecosystem
biotic factors living parts of an ecosystem
ecological pyramid diagram that shows the relative amounts of energy or matter within each trophic level in a food chain or food web
trophic level Each step in a food chain or food web
